A diverse superfamily of proteins that function as translocating proteins. They share the common characteristics of being able to bind ACTINS and hydrolyze MgATP. Myosins generally consist of heavy chains which are involved in locomotion, and light chains which are involved in regulation. Within the structure of myosin heavy chain are three domains: the head, the neck and the tail. The head region of the heavy chain contains the actin binding domain and MgATPase domain which provides energy for locomotion. The neck region is involved in binding the light-chains. The tail region provides the anchoring point that maintains the position of the heavy chain. The superfamily of myosins is organized into structural classes based upon the type and arrangement of the subunits they contain.

The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.

Evidence for F-actin-dependent and -independent mechanisms involved in assembly and stability of the medial actomyosin ring in fission yeast. (1/2643)

Cell division in a number of eukaryotes, including the fission yeast Schizosaccharomyces pombe, is achieved through a medially placed actomyosin-based contractile ring. Although several components of the actomyosin ring have been identified, the mechanisms regulating ring assembly are still not understood. Here, we show by biochemical and mutational studies that the S.pombe actomyosin ring component Cdc4p is a light chain associated with Myo2p, a myosin II heavy chain. Localization of Myo2p to the medial ring depended on Cdc4p function, whereas localization of Cdc4p at the division site was independent of Myo2p. Interestingly, the actin-binding and motor domains of Myo2p are not required for its accumulation at the division site although the motor activity of Myo2p is essential for assembly of a normal actomyosin ring. The initial assembly of Myo2p and Cdc4p at the division site requires a functional F-actin cytoskeleton. Once established, however, F-actin is not required for the maintenance of Cdc4p and Myo2p medial rings, suggesting that the attachment of Cdc4p and Myo2p to the division site involves proteins other than actin itself.  (+info)

Regulation of chamber-specific gene expression in the developing heart by Irx4. (2/2643)

The vertebrate heart consists of two types of chambers, the atria and the ventricles, which differ in their contractile and electrophysiological properties. Little is known of the molecular mechanisms by which these chambers are specified during embryogenesis. Here a chicken iroquois-related homeobox gene, Irx4, was identified that has a ventricle-restricted expression pattern at all stages of heart development. Irx4 protein was shown to regulate the chamber-specific expression of myosin isoforms by activating the expression of the ventricle myosin heavy chain-1 (VMHC1) and suppressing the expression of the atrial myosin heavy chain-1 (AMHC1) in the ventricles. Thus, Irx4 may play a critical role in establishing chamber-specific gene expression in the developing heart.  (+info)

Chlamydia infections and heart disease linked through antigenic mimicry. (3/2643)

Chlamydia infections are epidemiologically linked to human heart disease. A peptide from the murine heart muscle-specific alpha myosin heavy chain that has sequence homology to the 60-kilodalton cysteine-rich outer membrane proteins of Chlamydia pneumoniae, C. psittaci, and C. trachomatis was shown to induce autoimmune inflammatory heart disease in mice. Injection of the homologous Chlamydia peptides into mice also induced perivascular inflammation, fibrotic changes, and blood vessel occlusion in the heart, as well as triggering T and B cell reactivity to the homologous endogenous heart muscle-specific peptide. Chlamydia DNA functioned as an adjuvant in the triggering of peptide-induced inflammatory heart disease. Infection with C. trachomatis led to the production of autoantibodies to heart muscle-specific epitopes. Thus, Chlamydia-mediated heart disease is induced by antigenic mimicry of a heart muscle-specific protein.  (+info)

Processing of endogenous pre-mRNAs in association with SC-35 domains is gene specific. (4/2643)

Analysis of six endogenous pre-mRNAs demonstrates that localization at the periphery or within splicing factor-rich (SC-35) domains is not restricted to a few unusually abundant pre-mRNAs, but is apparently a more common paradigm of many protein-coding genes. Different genes are preferentially transcribed and their RNAs processed in different compartments relative to SC-35 domains. These differences do not simply correlate with the complexity, nuclear abundance, or position within overall nuclear space. The distribution of spliceosome assembly factor SC-35 did not simply mirror the distribution of individual pre-mRNAs, but rather suggested that individual domains contain both specific pre-mRNA(s) as well as excess splicing factors. This is consistent with a multifunctional compartment, to which some gene loci and their RNAs have access and others do not. Despite similar molar abundance in muscle fiber nuclei, nascent transcript "trees" of highly complex dystrophin RNA are cotranscriptionally spliced outside of SC-35 domains, whereas posttranscriptional "tracks" of more mature myosin heavy chain transcripts overlap domains. Further analyses supported that endogenous pre-mRNAs exhibit distinct structural organization that may reflect not only the expression and complexity of the gene, but also constraints of its chromosomal context and kinetics of its RNA metabolism.  (+info)

Myogenic signaling of phosphatidylinositol 3-kinase requires the serine-threonine kinase Akt/protein kinase B. (5/2643)

The oncogene p3k, coding for a constitutively active form of phosphatidylinositol 3-kinase (PI 3-kinase), strongly activates myogenic differentiation. Inhibition of endogenous PI 3-kinase activity with the specific inhibitor LY294002, or with dominant-negative mutants of PI 3-kinase, interferes with myotube formation and with the expression of muscle-specific proteins. Here we demonstrate that a downstream target of PI 3-kinase, serine-threonine kinase Akt, plays an important role in myogenic differentiation. Expression of constitutively active forms of Akt dramatically enhances myotube formation and expression of the muscle-specific proteins MyoD, creatine kinase, myosin heavy chain, and desmin. Transdominant negative forms of Akt inhibit myotube formation and the expression of muscle-specific proteins. The inhibition of myotube formation and the reduced expression of muscle-specific proteins caused by the PI 3-kinase inhibitor LY294002 are completely reversed by constitutively active forms of Akt. Wild-type cellular Akt effects a partial reversal of LY294002-induced inhibition of myogenic differentiation. This result suggests that Akt can substitute for PI 3-kinase in the stimulation of myogenesis; Akt may be an essential downstream component of PI 3-kinase-induced muscle differentiation.  (+info)

Coexistence of mitochondrial DNA and beta myosin heavy chain mutations in hypertrophic cardiomyopathy with late congestive heart failure. (6/2643)

OBJECTIVE: To investigate the possible coexistence of mitochondrial DNA (mtDNA) mutations in patients with beta myosin heavy chain (beta MHC) linked hypertrophic cardiomyopathy (HCM) who develop congestive heart failure. DESIGN: Molecular analysis of beta MHC and mtDNA gene defects in patients with HCM. SETTING: Cardiovascular molecular diagnostic and heart transplantation reference centre in north Italy. PATIENTS: Four patients with HCM who underwent heart transplantation for end stage heart failure, and after pedigree analysis of 60 relatives, eight additional affected patients and 27 unaffected relatives. A total of 111 unrelated healthy adult volunteers served as controls. Disease controls included an additional 27 patients with HCM and 102 with dilated cardiomyopathy. INTERVENTION: Molecular analysis of DNA from myocardial and skeletal muscle tissue and from peripheral blood specimens. MAIN OUTCOME MEASURES: Screening for mutations in beta MHC (exons 3-23) and mtDNA tRNA (n = 22) genes with denaturing gradient gel electrophoresis or single strand conformational polymorphism followed by automated DNA sequencing. RESULTS: One proband (kindred A) (plus seven affected relatives) had arginine 249 glutamine (Arg249Gln) beta MHC and heteroplasmic mtDNA tRNAIle A4300G mutations. Another unrelated patient (kindred B) with sporadic HCM had identical mutations. The remaining two patients (kindred C), a mother and son, had a novel beta MHC mutation (lysine 450 glutamic acid) (Lys450Glu) and a heteroplasmic missense (T9957C, phenylalanine (Phe)-->leucine (Leu)) mtDNA mutation in subunit III of the cytochrome C oxidase gene. The amount of mutant mtDNA was higher in the myocardium than in skeletal muscle or peripheral blood and in affected patients than in asymptomatic relatives. Mutations were absent in the controls. Pathological and biochemical characteristics of patients with mutations Arg249Gln plus A4300G (kindreds A and B) were identical, but different from those of the two patients with Lys450Glu plus T9957C(Phe-->Leu) mutations (kindred C). Cytochrome C oxidase activity and histoenzymatic staining were severely decreased in the two patients in kindreds A and B, but were unaffected in the two in kindred C. CONCLUSIONS: beta MHC gene and mtDNA mutations may coexist in patients with HCM and end stage congestive heart failure. Although beta MHC gene mutations seem to be the true determinants of HCM, both mtDNA mutations in these patients have known prerequisites for pathogenicity. Coexistence of other genetic abnormalities in beta MHC linked HCM, such as mtDNA mutations, may contribute to variable phenotypic expression and explain the heterogeneous behaviour of HCM.  (+info)

Altered crossbridge kinetics in the alphaMHC403/+ mouse model of familial hypertrophic cardiomyopathy. (7/2643)

A mutation in the cardiac beta-myosin heavy chain, Arg403Gln (R403Q), causes a severe form of familial hypertrophic cardiomyopathy (FHC) in humans. We used small-amplitude (0.25%) length-perturbation analysis to examine the mechanical properties of skinned left ventricular papillary muscle strips from mouse hearts bearing the R403Q mutation in the alpha-myosin heavy chain (alphaMHC403/+). Myofibrillar disarray with variable penetrance occurred in the left ventricular free wall of the alphaMHC403/+ hearts. In resting strips (pCa 8), dynamic stiffness was approximately 40% greater than in wild-type strips, consistent with elevated diastolic stiffness reported for murine hearts with FHC. At pCa 6 (submaximal activation), strip isometric tension was approximately 3 times higher than for wild-type strips, whereas at pCa 5 (maximal activation), tension was marginally lower. At submaximal calcium activation the characteristic frequencies of the work-producing (b) and work-absorbing (c) steps of the crossbridge were less in alphaMHC403/+ strips than in wild-type strips (b=11+/-1 versus 15+/-1 Hz; c= 58+/-3 versus 66+/-3 Hz; 27 degrees C). At maximal calcium activation, strip oscillatory power was reduced (0. 53+/-0.25 versus 1.03+/-0.18 mW/mm3; 27 degrees C), which is partly attributable to the reduced frequency b, at which crossbridge work is maximum. The results are consistent with the hypothesis that the R403Q mutation reduces the strong binding affinity of myosin for actin. Myosin heads may accumulate in a preforce state that promotes cooperative activation of the thin filament at submaximal calcium but blunts maximal tension and oscillatory power output at maximal calcium. The calcium-dependent effect of the mutation (whether facilitating or debilitating), together with a variable degree of fibrosis and myofibrillar disorder, may contribute to the diversity of clinical symptoms observed in murine FHC.  (+info)

Age-related changes in contractile properties of single skeletal fibers from the soleus muscle. (8/2643)

Peak absolute force, specific tension (peak absolute force per cross-sectional area), cross-sectional area, maximal unloaded shortening velocity (Vo; determined by the slack test), and myosin heavy chain (MHC) isoform compositions were determined in 124 single skeletal fibers from the soleus muscle of 12-, 24-, 30-, 36-, and 37-mo-old Fischer 344 Brown Norway F1 Hybrid rats. All fibers expressed the type I MHC isoform. The mean Vo remained unchanged from 12 to 24 mo but did decrease significantly from the 24- to 30-mo time period (from 1.71 +/- 0.13 to 0.85 +/- 0.09 fiber lengths/s). Fiber cross-sectional area remained constant until 36 mo of age, at which time there was a 20% decrease from the values at 12 mo of age (from 5,558 +/- 232 to 4,339 +/- 280 micrometer2). A significant decrease in peak absolute force of single fibers occurred between 12 and 24 mo of age (from 51 +/- 2 x 10(-5) to 35 +/- 2 x 10(-5) N) and then remained constant until 36 mo, when another 43% decrease occurred. Like peak absolute force, the specific tension decreased significantly between 12 and 24 mo by 20%, and another 32% decline was observed at 37 mo. Thus, by 24 mo, there was a dissociation between the loss of fiber cross-sectional area and force. The results suggest time-specific changes of the contractile properties with aging that are independent of each other. Underlying mechanisms responsible for the time-dependent and contractile property-specific changes are unknown. Age-related changes in the molecular dynamics of myosin may be the underlying mechanism for altered force production. The presence of more than one beta/slow MHC isoform may be the mechanism for the altered Vo with age.  (+info)

Postnatal myosin heavy chain isoform expression in normal mice and mice null for IIb or IId myosin heavy chains Journal Article ...
Purpose: Aging is associated with a decline in muscle volume, power output, and the velocity at which peak power (Vopt) occurs. The current study aimed to examine the relationship between lower-limb power output characteristics, muscle myosin heavy chain (MHC) composition, and lean limb volume. Methods: Lower-limb power output during repeated efforts on an inertial sprint cycle and single-leg thrusts on the modified Nottingham power rig was studied in seven young and seven old males in relation to muscle MHC isoform composition of the vastus lateralis. Results: Older subjects produced significantly lower power outputs and Vopt under all conditions (P , 0.01) and had lower proportions of fast MHC isoforms (P , 0.05). Peak power output during cycling was significantly related to lower-limb lean volume (r = 0.92, P , 0.05), whereas Vopt during sprint cycling was closely related to vastus lateralis MHC-II composition (r = 0.80, P , 0.05). Conclusions: These results provide further evidence of the ...
In the present study we aimed to determine the functional properties and the myosin heavy chain (MHC) isoform composition of single chemically skinned fibres from the vocal muscle of four adult men (age: 55-67 years). Single fibres, dissected from the bioptic samples, were chemically skinned and isometric tension (P0) and maximal shortening velocity (V0) were measured at pCa 4.6. MHC and myosin light chain (MLC) composition of fibre segments and MHC distribution of the biopsy samples were analysed by SDS-poly-acrylamide gel electrophoresis (SDS-PAGE) and densitometry. Four MHC isoforms (1, 2A, 2X and a fourth isoform, provisionally called L) and five MLC isoforms (MLC1s, MLC1f, MLC3f, MLC2f, MLC2s) were identified. The major findings of this study were: (1) fast MHC isoforms (in particular MHC-2A) and fast fibres were predominant, (2) one-third of the fibres were mixed or hybrid, i.e. expressed more than one MHC isoform, (3) V0 and P0 values were determined by the MHC isoform composition and ...

Y1 - 1996. N2 - The myosin heavy chain (MHC) is the site of ATP hydrolysis during crossbridge cycling; therefore, a correlation should exist between MHC isoform expression and actomyosin ATPase activity in human muscle fibers. Needle biopsies were obtained from the quadriceps femoris of 5 sedentary subjects (21-43 yr). Fibers were classified histochemicalîy and also on the basis of MHC isoform immunoreactivity. Calcium-activated actomyosin ATPase activity of muscle fibers (20 fibers per type) was determined in alternate serial sections using a quantitative histochemical procedure (Blanco & Sieck, Histochem J. 24: 431-444, 1992}. The mean actomyosin ATPase activity (mmol Pi/ liter tissue/min) of type I fibers (52.8±6.1) was two-fold lower (p,0.05) than that of type Ha (102.1 + 13.3) and type IIx ...

We report the cloning of cDNAs encoding two different human nonmuscle myosin heavy chains designated NMMHC-A and NMMHC-B. The mRNAs encoding NMMHC-A and NMMHC-B are both 7.5 kb in size but are shown to be the products of different genes, which are localized to chromosome 22q11.2 and chromosome 17q13, respectively. In aggreement with previously reported results using avian tissues, we show that the mRNAs encoding the two myosin heavy chain isoforms are differentially expressed in rat nonmuscle and muscle tissues as well as in a number of human cell lines. The cDNA sequence encoding the 5 portion of the NMMHC-A isoform completes the previously published 3 cDNA sequence encoding a human myosin heavy chain, thus providing the cDNA sequence encoding the entire NMMHC-A amino acid sequence. Comparison of this sequence to cDNA clones encoding the amino-terminal one third of the NMMHC-B sequence (amino acids 58-718) shows them to be 89% identical at the amino acid level and 74% identical at the ...

Introduction: We have reported previously that α-myosin heavy chain (α-MyHC) expressing myocytes (MCs), the predominant MC in adult mouse hearts, hypertrophy under pressure-overload without a proportionate increase in total MyHC protein (T-MyHC) content (Lopez et al, Circ. Res., 2011). It is not yet known if during normal physiological growth, these MCs increase their T-MyHC content in proportion to cell size.. Hypothesis: During normal post-natal growth, an increase in T-MyHC content is proportionate to changes in cardiac mass and MC size.. Methods: Individual cardiac cells were isolated by enzymatic digestion from male C57Bl/6 mice age in days 22+/-1 (young, n=4) and 88+/-6 (adult, n=4). Body and heart weights (wt), mean MC volumes by Coulter Multisizer (vol), and cell protein content-per-MC by BCA assay (TotProtMC) were used to measure cardiac growth. A new approach using large-particle fluorescent activated cell sorting (FACS, see Figure) was validated to isolate 15K Troponin-T expressing ...
We have investigated myosin isoform expression during progressive cardiac hypertrophy and the development of congestive heart failure in young male rats. Cardiac enlargement was produced by placing a constricting band (0.024-inch diameter) around the ascending aorta of 25-day-old animals, which resulted in progressively increased stenosis as the rat matured. A 57% and 77% cardiac hypertrophy was observed at 2 and 8 weeks, respectively, with signs of congestive failure at the latter time point. Myosin isoform expression was examined in the subendocardial and subepicardial myocardium of the left ventricle and the free wall of the right ventricle by use of native gel electrophoresis. The percentage of the V3 isoform increased dramatically in both ventricles. In the subendocardial myocardium of the left ventricle, expression of the V3 isoform increased (p less than or equal to 0.05) relative to the subepicardial myocardium at 2, 4, and 8 weeks (17.1% vs. 10.2%, 29.4% vs. 18%, and 46.6% vs. 36.2%). ...
A 25-year-old woman had childhood-onset muscle weakness and dilated cardiomyopathy. She exhibited predominantly distal weakness with early toe walking. Dilated cardiomyopathy required cardiac transplantation at age 15 years. We identified a de-novo, heterozygous, missense mutation, c.2348G>C (p. Arg783Pro), in exon 21 of the MYH7 gene, which encodes slow skeletal muscle fiber/β-cardiac myosin heavy chain protein, that replaces a highly conserved arginine with a proline. This novel mutation that results in the unusual combined cardiac and skeletal muscle phenotype localizes to the essential light chain binding area, a region only previously shown to be mutated in hypertrophic cardiomyopathy ...
Expression in the adult heart of a number of cardiac genes, including the two genes comprising the cardiac myosin heavy chain locus (Myh), is controlled by thyroid hormone (T3) levels, but there is minimal information concerning the epigenetic status of the genes when their expressions change. We fed mice normal chow or a propyl thio uracil (PTU, an inhibitor of T3 production) diet for 6 weeks, or the PTU diet for 6 weeks followed by normal chow for a further 2 weeks. Heart ventricles from these groups were then used for ChIP-seq analyses with an antibody to H3K4me3, a well-documented epigenetic marker of gene activation. The resulting data show that, at the Myh7 locus, H3K4me3 modifications are induced primarily at 5′ transcribed region in parallel with increased expression of beta myosin heavy chain (MHC). At the Myh6 locus, decreases in H3K4me3 modifications occurred at the promoter and 5′ transcribed region. Extensive H3K4me3 modifications also occurred at the intergenic region between ...

The myo2 gene product identified in this study showed similarity to the type II myosin heavy chain in a number of structural features. In addition, Myo2p colocalized with actin overlying mitotic nuclei and could be seen on a shrinking contractile ring. These results strongly suggest that Myo2p composes S. pombe type II myosin, which interacts with actin in the contractile ring and generates force for cytokinesis.. Type II myosin heavy chains known to date carry two IQ motifs, agreeing with the hexameric structure of myosin II. However, we found only one perfect IQ motif (IQXXXRGXXXR) at residues 765-775 in S. pombe Myo2p. A similar sequence to the IQ motif (LQANLQVYNEFR) exists at residues 791-802, but this sequence does not have the central arginine, which is believed to be critical for the binding to the myosin light chain. Thus, we suspect that the type II myosin heavy chain of S. pombe may interact with only one myosin light chain. Interestingly, McCollum et al. (27) observed in their ...
Introduction: The extraocular muscles (EOMs) are considered a separate class of skeletal muscle, allotype. Myosin is the major contractile protein in muscle. The myosin heavy chain (MyHC) isoforms are the best molecular markers of functional heterogeneity of muscle fibers. The relaxation rate, reflects the rate at which Ca2+ is transported back into the sarcoplasmic reticulum (SR) mostly by SR Ca2+ATPase (SERCA). Myosin binding protein C (MyBP-C), plays a physiological role in regulating contraction. The laminins (Ln) are the major non-collagenous components of the basement membrane (BM) surrounding muscle fibers and are important for muscle fiber integrity.. Methods: Adult human EOMs were studied with SDS-PAGE, immunoblots and immunocytochemistry, the latter with antibodies against six MyHC, 2 SERCA, 2 MyBP-C and 8 laminin chain isoforms. The capillary density was also determined.. Results: Most fibers contained a mixture of MyHC isoforms. Three major groups of fibers could be distinguished. ...
Colloidal gold-conjugated monoclonal antibodies were prepared to stage-specific fast myosin heavy chain (MHC) isoforms of developing chicken pectoralis major (PM). Native thick filaments from different stages of development were reacted with these antibodies and examined in the electron microscope to determine their myosin isoform composition. Filaments prepared from 12-d embryo, 10-d chick, and 1-yr chicken muscle specifically reacted with the embryonic (EB165), neonatal (2E9), and adult (AB8) antimyosin gold-conjugated monoclonal antibodies, respectively. The myosin isoform composition was more complex in thick filaments from stages of pectoral muscle where more than one isoform was simultaneously expressed. In 19-d embryo muscle where both embryonic and neonatal isoforms were present, three classes of filaments were found. One class of filaments reacted only with the embryonic antibody, a second class reacted only with the neonatal-specific antibody, and a third class of filaments were ...
The interaction between the calcium-binding protein S100A4 and the C-terminal fragments of nonmuscle myosin heavy chain IIA has been studied by equilibrium and kinetic methods. Using site-directed mutants, we conclude that Ca(2+) binds to the EF2 domain of S100A4 with micromolar affinity and that the K(d) value for Ca(2+) is reduced by several orders of magnitude in the presence of myosin target fragments. The reduction in K(d) results from a reduced dissociation rate constant (from 16 s(-1) to 0.3 s(-1) in the presence of coiled-coil fragments) and an increased association rate constant. Using peptide competition assays and NMR spectroscopy, we conclude that the minimal binding site on myosin heavy chain IIA corresponds to A1907-G1938; therefore, the site extends beyond the end of the coiled-coil region of myosin. Electron microscopy and turbidity assays were used to assess myosin fragment filament disassembly by S100A4. The latter assay demonstrated that S100A4 binds to the filaments and ...
MYH9-related disease (MYH9-RD) is a rare autosomal-dominant disorder caused by mutations in MYH9, the gene for the heavy chain of nonmuscle myosin IIA (NMMHC-IIA). All patients present from birth with macrothrombocytopenia, but in infancy or adult life, some of them develop sensorineural deafness, presenile cataracts, and/or progressive nephritis leading to end-stage renal failure. No consistent correlations have been identified between the 27 different MYH9 mutations identified so far and the variable clinical evolution of the disease. We have evaluated 108 consecutive MYH9-RD patients belonging to 50 unrelated pedigrees. The risk of noncongenital manifestations associated with different genotypes was estimated over time by event-free survival analysis. We demonstrated that all subjects with mutations in the motor domain of NMMHC-IIA present with severe thrombocytopenia and develop nephritis and deafness before the age of 40 years, while those with mutations in the tail domain have a much lower ...

AU - Zhan, Wen Zhi. AU - Sieck, Gary C.. PY - 2002. Y1 - 2002. N2 - We hypothesized that 1) hypothyroidism (Hyp) decreases myosin heavy chain (MHC) content per half-sarcomere in diaphragm muscle (Diam) fibers, 2) Hyp decreases the maximum specific force (Fmax) of Diam fibers because of the reduction in MHC content per half-sarcomere, and 3) Hyp affects MHC content per half-sarcomere and Fmax to a greater extent in fibers expressing MHC type 2X (MHC2X) and/or MHC type 2B (MHC2B). Studies were performed on single Triton X-permeabilized fibers activated at pCa 4.0. MHC content per half-sarcomere was determined by densitometric analysis of SDS-polyacrylamide gels and comparison with a standard curve of known MHC concentrations. After 3 wk of Hyp, MHC content per half-sarcomere was reduced in fibers expressing MHC2X ...

Y1 - 2004. N2 - The myocardial protective effects of trilinolein, isolated from the traditional Chinese herb Sanchi (Panax notoginseng),are thought to be related to its antioxidant activity. However, the intracellular mechanism underlying the protective effect of trilinolein in the heart remains unclear. In the present study, we investigated the effect of trilinolein on norepinephrine (NE)-induced protein synthesis in cardiomyocytes. Cultured neonatal rat cardiomyocytes were stimulated with NE, then protein content, [ 3H]-leucine incorporation, and β-myosin heavy ...
Mts1 protein (S100A4 according to a new classification) has been implicated in the formation of the metastatic phenotype via regulation of cell motility and invasiveness. Previously we have demonstrated that Mts1 protein interacted with the heavy chain of nonmuscle myosin in a calcium- dependent manner. To elucidate the role of the Mts1-myosin interaction, we mapped the Mts1-binding region on the myosin heavy chain molecule. We prepared proteolytically digested platelet myosin and a series of overlapped myosin heavy chain protein fragments and used them in a blot overlay with Mts1 protein. Here we report that the Mts1-binding site is located within a 29-amino acid region, at the C-terminal end of the myosin heavy chain (between 1909-1937 amino acids). Two-dimensional phosphopeptide analysis showed that Mts1 protein inhibits protein kinase C phosphorylation of the platelet myosin heavy chain at Ser-1917. We hypothesize that Mts1 protein regulates cytoskeletal dynamics of the metastatic cells ...
Slovenščina (Slovenian). In the present research we tried to prove, that specific myosin heavy chain is relat-ed to a prevalent metabolic type and that activ-ities of succinate-dehydrogenase and a glycerophosphate dehydrogenase in the same fibre types can be different in different muscles. We defined the muscle fibre types (I, IIA and IIB) on transversal sections of frozen muscles accord-ing to their myofibrillar ATPase activity in alka-line and acidic media. We excised extensor digitorum longus, tibialis anterior and diaphragm muscles of five Wistar rats. In the same fibres we immunohistochemically demonstrated myosin heavy chains (MHC) I, IIA, IIB and IIX and histochemically and histophotometrically deter-mined the activities of succinate-dehydrogenase and glycerophosphate dehydrogenase. On the basis of the measured values we differ-entiated fibres in oxydative, glycolytic and oxydative-glycolytic. We found out, that MHC I are present in type I fibres (in extensor digitorum longus muscle ...

Background: Reversible lysine-acetylation of proteins is regulated by histone acetyl transferases and deacetylases (HDACs). Previous studies from this laboratory have shown that a class-II HDAC, HDAC4 is associated with cardiac sarcomeres, and that HDAC-inhibitors enhance the contractile activity of myofilaments. Since, HDAC4 has little or no deacetylase activity of its own, this study was undertaken to examine the presence of other HDACs on cardiac sarcomeres.. Methods and Results: We prepared skinned papillary muscle fibers of the mouse heart and subjected them to western analysis. Results showed that a class-I HDAC, HDAC3 was localized to cardiac sarcomeres. By immuno-histochemical and electron microscopic analyses we found that HDAC3 was localized to the A-band of cardiac sarcomeres. We therefore examined the reversible acetylation of the A-band protein, myosin heavy chains (MHCs). MHC isoforms were prepared from control and PTU-treated mice, and examined for acetylation by western analysis ...
Three embryonic class II myosin heavy chains (MYHs) were cloned from the common carp (Cyprinus carpio L.), MYHemb1,MYHemb2 and MYHemb3. MYH DNA clones were also isolated from the slow muscle of adult carp acclimated to 10°C (MYHS10)and 30°C (MYHS30). Phylogenetic analysis demonstrated that MYHemb1 and MYHemb2 belonged to the fast skeletal muscle MYH clade. By contrast, the sequence of MYHemb3 was similar to the adult slow muscle isoforms, MYHS10 and MYHS30. MYHemb1 and MYHemb2 transcripts were first detected by northern blot analysis in embryos 61 h post-fertilization (h.p.f.) at the heartbeat stage, with peak expression occurring in 1-month-old juveniles. MYHemb1 continued to be expressed at low levels in 7-month-old juveniles when MYHemb2 was not detectable. MYHemb3transcripts appeared at almost the same stage as MYHemb1transcripts did (61 h.p.f.), and these genes showed a similar pattern of expression. Whole mount in situ hybridization analysis revealed that the transcripts of MYHemb1 and ...
The purpose of this investigation was to examine the effects of Multiple Sclerosis (MS) on the structural and functional characteristics of skeletal muscle. More specifically, we analyzed the myosin heavy chain (MHC) and fiber type distribution of the vastus lateralis, measured single fiber cross sectional area (CSA), and determined the isokinetic and isotonic strength of the knee extensor muscles. Six sedentary subjects with MS (age: 44 ± 2 yrs) and six sedentary gender-matched controls (age: 46 ± 4) were evaluated. EachMS subject was rated on the Kurtzkes Expanded Disability Status Scale (EDSS) and performed an 8-meter walk test to determine gait speed. Furthermore, the spasticity of the knee extensors was evaluated in each MS subject and weekly energy expenditure was estimated using the Yale Physical Activity Survey. Concentric and eccentric isokinetic strength of the right knee extensors (left in one MS subject) was determined at 60 and 180°/sec and a bilateral isotonic one-repetition ...
Familial hypertrophic cardiomyopathy (FHCM) is an autosomal dominant disease with protean clinical manifestations, ranging from asymptomatic to that of severe heart failure or sudden death. There ist no known parameter in individuals with hypertrophic cardiomyopathy (HCM) that predicts a specific clinical event. This is particularly troublesome for premature sudden death that frequently occurs in young athletes without prior symptoms. Recent identifications of mutations in the beta-myosin heavy chain (betaMHC) gene that co-segregate with the inheritance of the disease provides an opportunity to determine whether certain mutations are more likely to induce a particular clinical event. In this study we analyzed the genotype and phenotype of individuals from two unrelated families with HCM in which the affected individuals have the same missense mutation in exon 13 (G1208A) of the coding sequence for betaMHC. Results: We studied 54 individuals from the two families, 21 were affected with HCM of ...

In smooth muscle cells (SMCs) isolated from rabbit carotid, femoral, and saphenous arteries, relative myosin isoform mRNA levels were measured in RT-PCR to test for correlations between myosin isoform expression and unloaded shortening velocity. Unloaded shortening velocity and percent smooth muscle myosin heavy chain 2 (SM2) and myosin light chain 17b (MLC17b) mRNA levels were not significantly different in single SMCs isolated from the luminal and adluminal regions of the carotid media. Saphenous artery SMCs shortened significantly faster (P | 0.05) than femoral SMCs and had more SM2 mRNA (P | 0.05) than carotid SMCs and less MLC17b mRNA (P | 0.001) and higher tissue levels of SMB mRNA (P | 0.05) than carotid and femoral SMCs. No correlations were found between percent SM2 and percent MLC17b mRNA levels and unloaded shortening velocity in SMCs from these arteries. We have previously shown that myosin heavy chain (MHC) SM1/SM2 and SMA/SMB and MLC17a/MLC17b isoform mRNA levels correlate with protein
Myosin-1, also known as striated muscle myosin heavy chain 1, is a protein that in humans is encoded by the MYH1 gene. This gene is most highly expressed in fast type IIX/D muscle fibres of vertebrates and encodes a protein found uniquely in striated muscle; it is a class II myosin with a long coiled coil tail that dimerizes and should not be confused with Myosin 1 encoded by the MYO1 family of genes (MYO1A-MYO1H). Class I MYO1 genes function in many cell types throughout biology and are single-headed membrane-binding myosins that lack a long coiled coil tail. Myosin is a major contractile protein that converts chemical energy into mechanical energy through the hydrolysis of ATP. Class II Myosins are hexameric proteins composed of a pair of myosin heavy chains (MYH) and two pairs of nonidentical light chains. Myosin heavy chains are encoded by a multigene family. In mammals, at least ten different myosin heavy chain (MYH) isoforms have been described from striated, smooth, but rarely in ...

To test the quality of the new algorithm, several well-known genes with clusters of mutually exclusive exons with different characteristics were analysed (Figure 3). The first test case is the cytoplasmic dynein heavy chain from Schistosoma mansoni (Sm DHC1). Dynein heavy chains belong to the longest genes in eukaryotes encoding 4000 - 5000 residues and are spread over several dozens of exons. The mutually exclusive exon is clearly identified in the middle of the gene, encoding split codons at the 3- and 5-end of the exon. The query exon and the candidate exon have identical lengths and show strong homology. Based on the multiple sequence alignment of more than 2000 DHCs these exons are mutually exclusive and not constitutive or differentially included. The second case represents the muscle myosin heavy chain gene from the waterflea Daphnia magna[19]. The arthropod muscle myosin heavy chain genes contain several clusters of mutually exclusive exons to fine tune the mechanochemical ...

Myosin-3 is a protein that in humans is encoded by the MYH3 gene. Myosin is a major contractile protein which converts chemical energy into mechanical energy through the hydrolysis of ATP. Myosin is a hexameric protein composed of a pair of myosin heavy chains (MYH) and two pairs of nonidentical light chains. This gene is a member of the MYH family and encodes a protein with an IQ domain and a myosin head-like domain. Mutations in this gene have been associated with two congenital contracture (arthrogryposis) syndromes, Freeman-Sheldon syndrome and Sheldon-Hall syndrome.

A myosin complex containing one or more class XVII myosin heavy chains and associated light chains. [http://www.mrc-lmb.cam.ac.uk/myosin/Review/Reviewframeset.html]
The polarisome is a cortical proteinaceous microcompartment that organizes the growth of actin filaments and the fusion of secretory vesicles in yeasts and filamentous fungi. Polarisomes are compact, spotlike structures at the growing tips of their respective cells. The molecular forces that control the form and size of this microcompartment are not known. Here we identify a complex between the polarisome subunit Pea2 and the type V Myosin Myo2 that anchors Myo2 at the cortex of yeast cells. We discovered a point mutation in the cargo-binding domain of Myo2 that impairs the interaction with Pea2 and consequently the formation and focused localization of the polarisome. Cells carrying this mutation grow round instead of elongated buds. Further experiments and biophysical modeling suggest that the interactions between polarisome-bound Myo2 motors and dynamic actin filaments spatially focus the polarisome and sustain its compact shape ...
