Glu300 of rat carboxypeptidase E is essential for enzymatic activity but not substrate binding or routing to the regulated secretory pathway. (1/106)

Several recently discovered members of the carboxypeptidase E (CPE) gene family lack critical active site residues that are conserved in other family members. For example, three CPE-like proteins contain a Tyr in place of Glu300 (equivalent to Glu270 of carboxypeptidase A and B). To investigate the importance of this position, Glu300 of rat CPE was converted into Gln, Lys, or Tyr, and the proteins expressed in Sf9 cells using the baculovirus system. All three mutants were secreted from the cells, but the media showed no enzyme activity above background levels. Wild-type CPE and the Gln300 point mutant bound to a p-aminobenzoyl-Arg-Sepharose affinity resin, and this binding was competed by an active site-directed inhibitor, guanidinoethylmercaptosuccinic acid. The affinity purified mutant CPE protein showed no detectable enzyme activity (<0.004% of wild-type CPE) toward dansyl-Phe-Ala-Arg. Expression of the Gln300 and Lys300 mutant CPE proteins in the NIT3 mouse pancreatic beta-cell line showed that these mutants are routed into secretory vesicles and secreted via the regulated pathway. Taken together, these results indicate that Glu300 of CPE is essential for enzyme activity, but not required for substrate binding or for routing into the regulated secretory pathway.  (+info)

Biosynthesis and packaging of carboxypeptidase D into nascent secretory vesicles in pituitary cell lines. (2/106)

Metallocarboxypeptidase D (CPD) is a membrane-bound trans-Golgi network (TGN) protein. In AtT-20 cells, CPD is initially produced as a 170-kDa endoglycosidase H-sensitive glycoprotein. Within 30 min of chase, the CPD increases to 180 kDa and is resistant to endoglycosidase H as a result of carbohydrate maturation. CPD also undergoes an activation step required for binding to a substrate affinity resin. Blocking the protein exit from the endoplasmic reticulum inhibits the increase in molecular mass but not the step required for affinity column binding, suggesting that enzyme activation precedes carbohydrate maturation and that these reactions occur in distinct intracellular compartments. Only the higher molecular weight mature CPD enters nascent secretory vesicles, which bud from the TGN of permeabilized AtT-20 and GH3 cells. The budding efficiency of CPD into vesicles is 2-3-fold lower than that of endogenous proopiomelanocortin in AtT-20 cells or prolactin in GH3 cells. In contrast, the packaging of a truncated form of CPD, which lacks the cytoplasmic tail and transmembrane domain, was similar to that of proopiomelanocortin. Taken together, the results support the proposal that CPD functions in the TGN in the processing of proteins that transit the secretory pathway and that the C-terminal region plays a major role in TGN retention.  (+info)

Identification and characterization of proSAAS, a granin-like neuroendocrine peptide precursor that inhibits prohormone processing. (3/106)

Five novel peptides were identified in the brains of mice lacking active carboxypeptidase E, a neuropeptide-processing enzyme. These peptides are produced from a single precursor, termed proSAAS, which is present in human, mouse, and rat. ProSAAS mRNA is expressed primarily in brain and other neuroendocrine tissues (pituitary, adrenal, pancreas); within brain, the mRNA is broadly distributed among neurons. When expressed in AtT-20 cells, proSAAS is secreted via the regulated pathway and is also processed at paired-basic cleavage sites into smaller peptides. Overexpression of proSAAS in the AtT-20 cells substantially reduces the rate of processing of the endogenous prohormone proopiomelanocortin. Purified proSAAS inhibits prohormone convertase 1 activity with an IC(50) of 590 nM but does not inhibit prohormone convertase 2. Taken together, proSAAS may represent an endogenous inhibitor of prohormone convertase 1.  (+info)

Lipid raft association of carboxypeptidase E is necessary for its function as a regulated secretory pathway sorting receptor. (4/106)

Membrane carboxypeptidase E (CPE) is a sorting receptor for targeting prohormones, such as pro-opiomelanocortin, to the regulated secretory pathway in endocrine cells. Its membrane association is necessary for it to bind a prohormone sorting signal at the trans-Golgi network (TGN) to facilitate targeting. In this study, we examined the lipid interaction of CPE in bovine pituitary secretory granule membranes, which are derived from the TGN. We show that CPE is associated with detergent-resistant lipid domains, or rafts, within secretory granule membranes. Lipid analysis revealed that these rafts are enriched in glycosphingolipids and cholesterol. Pulse-chase and subcellular fractionation experiments in AtT-20 cells show that the association of CPE with membrane rafts occurred only after it reached the Golgi. Cholesterol depletion resulted in dissociation of CPE from secretory granule membranes and decreased the binding of prohormones to membranes. In vivo cholesterol depletion using lovastatin resulted in the lack of sorting of CPE and its cargo to the regulated secretory pathway. We propose that the sorting receptor function of CPE necessitates its interaction with glycosphingolipid-cholesterol rafts at the TGN, thereby anchoring it in position to bind to its prohormone cargo.  (+info)

Oligomerization of pro-opiomelanocortin is independent of pH, calcium and the sorting signal for the regulated secretory pathway. (5/106)

Studies indicate that pro-opiomelanocortin (POMC) is sorted to the regulated secretory pathway by binding to a sorting receptor identified as membrane-bound carboxypeptidase E (CPE) [Cool et al. (1997) Cell 88, 73-83]. The efficiency of this sorting mechanism could be enhanced if POMC molecules were to self-associate to form oligomers, prior or subsequent to binding to CPE. Using cross-linking and gel filtration techniques, we demonstrated that POMC forms oligomers at both neutral and acidic pHs and calcium was not necessary. delta N-POMC, which lacks the N-terminal sorting signal for the regulated secretory pathway, also formed similar oligomers, indicating that the sorting and oligomerization domains are different.  (+info)

Impaired prohormone convertases in Cpe(fat)/Cpe(fat) mice. (6/106)

A spontaneous point mutation in the coding region of the carboxypeptidase E (CPE) gene results in a loss of CPE activity that correlates with the development of late onset obesity (Nagert, J. K., Fricker, L. D., Varlamov, O., Nishina, P. M., Rouille, Y., Steiner, D. F., Carroll, R. J., Paigen, B. J., and Leiter, E. H. (1995) Nat. Genet. 10, 135-142). Examination of the level of neuropeptides in these mice showed a decrease in mature bioactive peptides as a result of a decrease in both carboxypeptidase and prohormone convertase activities. A defect in CPE is not expected to affect endoproteolytic processing. In this report we have addressed the mechanism of this unexpected finding by directly examining the expression of the major precursor processing endoproteases, prohormone convertases PC1 and PC2 in Cpe(fat) mice. We found that the levels of PC1 and PC2 are differentially altered in a number of brain regions and in the pituitary. Since these enzymes have been implicated in the generation of neuroendocrine peptides (dynorphin A-17, beta-endorphin, and alpha- melanocyte-stimulating hormone) involved in the control of feeding behavior and body weight, we compared the levels of these peptides in Cpe(fat) and wild type animals. We found a marked increase in the level of dynorphin A-17, a decrease in the level of alpha-melanocyte-stimulating hormone, and an alteration in the level of C-terminally processed beta-endorphin. These results suggest that the impairment in the level of these and other peptides involved in body weight regulation is mainly due to an alteration in carboxypeptidase and prohormone convertase activities and that this may lead to the development of obesity in these animals.  (+info)

ProSAAS processing in mouse brain and pituitary. (7/106)

ProSAAS is a newly discovered protein with a neuroendocrine distribution generally similar to that of prohormone convertase 1 (PC1), a peptide-processing endopeptidase. Several proSAAS-derived peptides were previously identified in the brain and pituitary of the Cpe(fat)/Cpe(fat) mouse based on the accumulation of C-terminally extended peptides due to the absence of enzymatically active carboxypeptidase E, a peptide-processing exopeptidase. In the present study, antisera against different regions of proSAAS were used to develop radioimmunoassays and examine the processing profile of proSAAS in wild type and Cpe(fat)/Cpe(fat) mouse tissues following gel filtration and reverse phase high performance liquid chromatography. In wild type mouse brain and pituitary, the majority of proSAAS is processed into smaller peptides. These proSAAS-derived peptides elute from the reverse-phase column in the same positions as synthetic peptides that correspond to little SAAS, PEN, and big LEN. Mass spectrometry revealed the presence of peptides with the expected molecular masses of little SAAS and big LEN in the fractions containing immunoreactive peptides. The processing of proSAAS is slightly impaired in Cpe(fat)/Cpe(fat) mice, relative to wild-type mice, leading to the accumulation of partially processed peptides. One of these peptides, the C-terminally extended form of PEN, is known to inhibit PC1 activity and this could account for the reduction in enzymatically active PC1 seen in Cpe(fat)/Cpe(fat) mice. The observation that little SAAS and big LEN are the major forms of these peptides produced in mouse brain and pituitary raises the possibility that these peptides function as neurotransmitters or hormones.  (+info)

Cholesterol, a cell size-dependent signal that regulates glucose metabolism and gene expression in adipocytes. (8/106)

Enlarged fat cells exhibit modified metabolic capacities, which could be involved in the metabolic complications of obesity at the whole body level. We show here that sterol regulatory element-binding protein 2 (SREBP-2) and its target genes are induced in the adipose tissue of several models of rodent obesity, suggesting cholesterol imbalance in enlarged adipocytes. Within a particular fat pad, larger adipocytes have reduced membrane cholesterol concentrations compared with smaller fat cells, demonstrating that altered cholesterol distribution is characteristic of adipocyte hypertrophy per se. We show that treatment with methyl-beta-cyclodextrin, which mimics the membrane cholesterol reduction of hypertrophied adipocytes, induces insulin resistance. We also produced cholesterol depletion by mevastatin treatment, which activates SREBP-2 and its target genes. The analysis of 40 adipocyte genes showed that the response to cholesterol depletion implicated genes involved in cholesterol traffic (caveolin 2, scavenger receptor BI, and ATP binding cassette 1 genes) but also adipocyte-derived secretion products (tumor necrosis factor alpha, angiotensinogen, and interleukin-6) and proteins involved in energy metabolism (fatty acid synthase, GLUT 4, and UCP3). These data demonstrate that altering cholesterol balance profoundly modifies adipocyte metabolism in a way resembling that seen in hypertrophied fat cells from obese rodents or humans. This is the first evidence that intracellular cholesterol might serve as a link between fat cell size and adipocyte metabolic activity.  (+info)

A similar enzyme is present in many brain regions1,2 and in purified secretory granules from rat pituitary3 and rat insulinoma4. Within the secretory granules, carboxypeptidase E (CPE) activity is found in both a soluble and a membrane-bound form1, which differ slightly in relative molecular mass (Mr)5. Here, to investigate whether the CPE activities in the various tissues are produced from a single gene, purified CPE was partially sequenced and oligonucleotide probes were used to isolate a clone encoding CPE from a bovine pituitary complementary DNA library. This cDNA hybridizes to bovine pituitary poly(A)+ ...
50) was found to have a mutation that deleted nearly the entire CPE gene. This patient had intellectual disability (inability to read or write) and had abnormal glucose homeostasis, similar to mice lacking CPE activity. In obesity, high levels of circulating free fatty acids have been reported to cause a decrease in the amount of carboxypeptidase E protein in pancreatic beta-cells, leading to beta-cell dysfunction (hyperproinsulinemia) and increased beta-cell apoptosis (via an increase in ER-stress). However, because CPE is not a rate-limiting enzyme for the production of most neuropeptides and peptide hormones, it is not clear how relatively modest decreases in CPE activity can cause physiological effects.

N2 - Neuroendocrine peptides play important roles as intercellular messengers. We previously developed a technique to isolate and identify a large number of neuroendocrine peptides from Cpefat/Cpefat mice (Che, F.; et al. Proc. Natl. Acad. Sci. U.S.A. 2001, 98, 9971-6); these mice lack carboxypeptidase E activity and this defect causes an accumulation of neuropeptide intermediates that contain C-terminal Lys or Arg residues (Naggert, J. K.; et al. Nat. Genet. 1995, 10, 135-42). In the present study, we have developed a differential isotopic-labeling technique that can be used to quantitate changes in neuropeptide levels in Cpefat/Cpefat mouse tissues. Samples are treated with either the H6 or the D6 form of acetic anhydride, peptides that contain C-terminal basic amino acids are isolated by affinity ...
Carboxypeptidase E (CPE) is a prohormone/proneuropeptide handling enzyme and mice bearing CPE mutations display an obese and diabetic phenotype. The melanocortin and neuropeptide Y (NPY) systems in the hypothalamus are also implicated in bone tissue redecorating since MC4R KO and NPY KO mice possess elevated BMD. However reduced amount of α-MSH the principal ligand of MC4R by up to 94% AZD2014 and having less detectable NPY in the hypothalamus of CPE KO usually do not ACAD9 recapitulate the single-gene KO phenotypes.

Pauls, D., et al. Drosophila carboxypeptidase D (SILVER) is a key enzyme in neuropeptide processing required to maintain locomotor activity levels and survival rate. 10.1111/ejn.14516. Neuropeptides are processed from larger preproproteins by a dedicated set of enzymes. The molecular and biochemical mechanisms underlying preproprotein processing and the functional importance of processing enzymes are well‐characterised in mammals, but little studied outside this group. In contrast to mammals, Drosophila melanogaster lacks a gene for carboxypeptidase E (CPE), a key enzyme for mammalian peptide processing. By combining peptidomics and neurogenetics, we addressed the role of carboxypeptidase D (dCPD) in global neuropeptide processing and selected peptide‐regulated behaviours in Drosophila. We found that a deficiency in dCPD results in C‐terminally extended peptides across the peptidome, suggesting that dCPD took over CPE function in the fruit fly. dCPD is widely expressed throughout the ...

Lets start with the basics of what leptin is and what it does. It is known as the "satiety hormone" and this might help give you an idea of what it does. This is a hormone that inhibits hunger to help regulate energy balance. Heres the thing about this type of hormone, it has an antagonist, or a hormone that does the exact opposite, that is to make us feel hungry. The body works in this way to maintain a balance. This hormone is called ghrelin, the "hunger hormone".. The problem with diets is that people think of them as a short-term plan that they will abandon once the fitness goal is achieved. They do not really make any lasting changes to their lifestyles. The other issue is that whenever you apply certain stress to the body, the body will always respond to compensate for any loss. In other words, if you make your body hungry, it will react by finding mechanisms to keep the energy balance, therefore, making you hungrier.. When leptin was first found to make fat mice lose weight, it was ...
As often happens with nutrition research, results from fasting research have been borrowed and packaged into ill-informed fad diets. Pandas research formed the basis of one such product, branded as The 8-Hour Diet. The book, cowritten by an editor at Mens Health, which covered Pandas research when it came out in 2012, claimed (right on the cover) that dieters who restricted their food consumption to an eight-hour window every day could "watch the pounds disappear without watching what you eat!" This idea, says Panda-who was not involved in producing the book-was unsupported by his research as of 2012. "We never claimed that we could make fat mice lean with the eight-hour diet," he says. "In our first paper, we just prevented obesity from happening.". Nevertheless, Panda has gone on to show that there may be some substance to the weight-loss hype. In addition to his experiments in mice, Pandas team found that flies, too, experienced benefits from restricting their feeding windows to a ...

We have cloned the cDNA for human carboxypeptidase D (CPD), a new B-type metallocarboxypeptidase that is membrane bound and has an acidic pH optimum. The 5.8 kb of cDNA sequenced contains an open reading frame of 4131 bp encoding 1377 amino acid residues. The sequence is similar (75% identity) to duck gp180, a protein that was isolated, cloned and sequenced as a hepatitis B virus-binding protein but not characterized as a carboxypeptidase. Hydropathic analysis revealed a hydrophobic region at the N-terminus, representing the signal peptide, and one near the C-terminus that probably represents the transmembrane anchor. The most striking feature is the presence of three tandem carboxypeptidase homology domains that have sequence similarity to the regulatory B-type carboxypeptidase family, typified by carboxypeptidases M, E and N. Because of the three repeats, CPD is about three times larger (175-180 kDa) than other members of this family (approx. 50-62 kDa). Domain 2 is most closely related to ...
Treatment of cultured bovine adrenal chromaffin cells with the catecholamine transport blocker reserpine was previously shown to increase enkephalin levels several-fold. To explore the biochemical mechanism of this effect, we examined the effect of reserpine treatment on the activities of three different peptide precursor processing enzymes: carboxypeptidase E (CPE) and the prohormone convertases (PCs) PC1/3 and PC2. Reserpine treatment increased both CPE and PC activity in extracts of cultured chromaffin cells; total protein levels were unaltered for any enzyme. Further analysis showed that the increase in CPE activity was due to an elevated Vmax, with no change in the Km for substrate hydrolysis or the levels of CPE mRNA. Reserpine activation of endogenous processing enzymes was also observed in extracts prepared from PC12 cells stably expressing PC1/3 or PC2. In vitro experiments using purified enzymes showed that catecholamines inhibited CPE, PC1/3 and PC2, with dopamine quinone the most ...
TY - JOUR. T1 - Intracellular trafficking of metallocarboxypeptidase D in AtT-20 cells. T2 - Localization to the trans-Golgi network and recycling from the cell surface. AU - Varlamov, Oleg. AU - Fricker, Lloyd D.. PY - 1998. Y1 - 1998. N2 - Carboxypeptidase D (CPD) is a recently discovered membrane-bound metallocarboxypeptidase that has been proposed to be involved in the post-translational processing of peptides and proteins that transit the secretory pathway. In the present study, the intracellular distribution of CPD was examined in AtT-20 cells, a mouse anterior pituitary-derived corticotroph. Antisera to CPD stain the same intracellular structures as those labeled with furin and wheat germ agglutinin. This distribution is distinct from carboxypeptidase E, which is localized to the secretory vesicles in the cell processes. The perinuclear distribution of CPD is detected even when the AtT-20 cells are treated with brefeldin A for 1-30 minutes, suggesting that CPD is present in the ...

To investigate the transcriptional regulation of the ACLP gene in VSMCs, we cloned and analyzed its promoter first in vitro and then in vivo. The single-copy mouse ACLP gene is composed of many small, closely spaced exons (Figure 1). The exon structure of the discoidin domain of ACLP is generally conserved with other discoidin domains containing proteins such as coagulation factor VIII37 and the discoidin domain tyrosine kinase receptors.38 In addition, the carboxypeptidase-like domain of mouse ACLP is similar in structure to the rat carboxypeptidase E gene.39 It is possible that ACLP could have been generated during evolution through the process of exon shuffling.40. The ACLP promoter is regulated in RASMCs via a strong positive element (−156 to −122) (Figure 4), which is bound and transactivated by Sp1 and Sp3 transcription factors (Figures 5 through 7⇑⇑). Sp1 and Sp3 are ubiquitously expressed proteins that regulate numerous genes.41 It is difficult to explain the regulation of VSMC ...

In the study, the researchers fed mice a diet of either saturated, monounsaturated or polyunsaturated fats, and compared them to mice genetically designed to develop Alzheimers.. Within two months, the mice that were fed a saturated fat diet showed significant change in their blood vessels.. "We saw a very substantial deterioration in the mice blood vessel architecture," says Mamo. "But, we saw no deterioration in the mice fed monounsaturated or polyunsaturated diets.". The saturated fat mice also had more amyloid deposits in their brain than those fed the monounsaturated or polyunsaturated diets.. The researchers also found that the brains of the mice fed the saturated fat diet were remarkably similar to the Alzheimers mouse models. "In mice that have been genetically manipulated to overproduce amyloid, we find exactly the same kind of pathology," says Mamo.. Using antibodies with a fluorescent tag the researchers were able to confirm that dietary fats are also found inside the amyloid ...
The purpose of this study was to determine if any factors immediately upstream of the fimA operon were associated with adherence or survival within the host. Just 148 bp upstream and divergently transcribed from the fimA operon, a 1,893-bp ORF (pepO) that encodes a protein with many structural features in common with the M13 (neprilysin) family of metallopeptidases was identified. This family of metallopeptidases includes bacterial members as well as mammalian neuropeptide-processing, immunoregulatory, and peptide hormone-processing zinc metallopeptidases (36). While the role of the bacterial enzymes is uncertain, the mammalian enzymes have been shown to play essential roles in events such as inflammatory response phenomena and in pain and cardiovascular regulation (45, 51, 52).. FW213 PepO contains the essential HEXXH consensus motif typical of this family of peptidases as well as numerous positionally conserved residues known to be critical for the activity of the mammalian enzymes. Some of ...
The BDNF secretion can be either constitutive or, more frequently, regulated by stimuli.32 This activity-dependent secretion, a feature characteristic of BDNF and not of any other neurotrophin or growth factor,33 may be an important factor in mood regulation. Along with slow effects that require protein synthesis, BDNF exerts rapid signaling events that regulate synaptic plasticity.34 For example, inducing phosphorylation of synapsin and thereby increasing glutamate and GABA release.35 BDNF can also increase ion influx through N-methyl-D-aspartate receptors and then synaptic strength.36 Thus, BDNF is able to regulate synaptic plasticity and recent findings suggest that mood disorders would be associated with alterations in information processing within neural networks.37 A large proportion of neuronal BDNF is secreted in the pro-form (proBDNF) which is subsequently converted to the mature form (mBDNF) by endoproteolytic cleavage.38 Lee et al.39 suggested that the extracellular conversion from ...

Competitive inhibition constants Ki for a series of phenol-ring-substituted derivatives of alpha-(2-hydroxyphenyl)benzenepropanoic acid have been ascertained by observing their influence on the catalytic hydrolysis of a peptide substrate by the zinc enzyme carboxypeptidase A. The pH-dependence of Ki shows that binding is maximal between two pKa values: one is that of the phenol group of the inhibitor, and the other uniformly has a value of 6, the pKa of a Zn(2+)-bound water molecule on the enzyme in the absence of substrate or inhibitor. This is the dependence expected if phenolate binds to the Zn2+ displacing its bound H2O/HO-. A log-log plot of the dissociation constants for the productive forms of inhibitor plus enzyme versus the acid dissociation constants of the phenolic residues in the inhibitors yields a straight line with a slope of +0.76. This number indicates that the active-site metal ion has special capacity for dispersing negative charge, such as builds up on the oxygen atom of a ...
Raising your carnitine levels will fight this visceral fat gain because it increases fat burning, which has the effect of taking triglycerides and low-density lipoproteins out of the system so that they dont build up causing high cholesterol and atherosclerosis. A new research study in the journal Food and Chemical Toxicology illustrates this. Researchers gave a carnitine supplement to mice who were fed a high-fat diet in order to make them gain weight. In comparison to a group of mice fed a placebo, the carnitine group gained substantially less visceral and subcutaneous fat (fat that is right below the surface of the skin that you can pinch with your fingers). The placebo group exhibited the beginning stages of non-alcoholic fatty liver disease and atherosclerosis, neither of which were evident in the carnitine group ...

Carboxypeptidases are enzymes that hydrolyze C-terminal peptide bonds. The carboxypeptidase family includes metallo-, serine, and cysteine carboxypeptidases. According to their substrate specificity, these enzymes are referred to as carboxypeptidase A (cleaving aliphatic residues) or carboxypeptidase B (cleaving basic amino residues). The protein encoded by this gene is activated by trypsin and acts on carboxypeptidase B substrates. After thrombin activation, the mature protein downregulates fibrinolysis. Polymorphisms have been described for this gene and its promoter region. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Jun 2013 ...

Previously, heterozygous INS gene mutations had been detected in adult patients with so-called familial hyperinsulinemia or hyperproinsulinemia who presented with variable phenotypes (mild diabetes or even hypoglycemia) and high serum levels of radioimmunoassayable insulin or proinsulin-like material. More recently, INS mutations have been found to be associated with neonatal- and infancy-onset diabetes (1-3). We demonstrated that mutant insulins with proteotoxic effect cannot be secreted when expressed in HEK 293 cell line (1), and it is likely that SB8 and SSignal23 are also retained in the endoplasmic reticulum. Nevertheless, the patient bearing the mutation in the signal peptide shows a milder clinical course, and we cannot exclude that SSignal23 preproinsulin may be partially processed and secreted. Present knowledge indicates that insulin mutations with a proteotoxic effect cause apoptosis of the pancreatic β-cell (1), a process that in most patients takes several months after birth (1-3) ...

Structure of the carboxypeptidase b complex with n-sulfamoyl-l-phenylalanine - a transition state analog of non-specific substrate / V. Akparov, V. Timofeev, I. Khaliullin et al. // Journal of Biomolecular Structure and Dynamics, издательство Taylor & Francis. - 2017. Carboxypeptidase B (EC 3.4.17.2) (CPB) is commonly used in the industrial insulin production and as a template for drug design. However, its ability to discriminate substrates with hydrophobic, hydrophilic, and charged side chains is not well understood. We report structure of CPB complex with a transition state analog N-sulfamoyl-L-phenylalanine solved at 1.74Å. The study provided an insight into structural basis of CPB substrate specificity. Ligand binding is affected by structure-depended conformational changes of Asp255 in S1-subsite, interactions with Asn144 and Arg145 in C-terminal binding subsite, and Glu270 in the catalytic center. Side chain of the non-specific substrate analog SPhe in comparison with that of ...
This gene encodes a neuroendocrine peptide that is widely expressed in the central and peripheral nervous systems and also the gastrointestinal tract, pancreas, adrenal gland and urogenital tract. The encoded protein is a precursor that is proteolytically processed to generate two mature peptides: galanin and galanin message-associated peptide (GMAP). Galanin has diverse physiological functions including nociception, feeding and energy homeostasis, osmotic regulation and water balance. GMAP has been demonstrated to possess antifungal activity and hypothesized to be part of the innate immune system. [provided by RefSeq, Jul 2015 ...

Gastrin-releasing peptide (GRP) is the mammalian analogue of bombesin. Both neuroendocrine peptides have similar distribution, functions and immunoreactivity. The immunoreactivity for GRP has been demonstrated in the esophagus, stomach and small intestine. This peptide is reported to have various biological and pharmacological properties, which include the release of gastrointestinal hormones, control of satiety, gastrointestinal motility and stimulation of cellular proliferation which results in wound healing. It is also implicated in the proliferation of many gastrointestinal (GI), renal and prostatic tumours. Transient increase in GRP synthesis in the brain and serum concentration, which was later followed by decreased serum concentration, has been reported in hyperglycemic states. The aim of this investigation was to determine the effect of hyperglycemia on GRP secreting neurons in the sub mucosa of the GIT and how this may affect some of the GI complications of diabetes.

Vasoactive intestinal peptide (VIP) is a neuroendocrine peptide that has been implicated in a myriad of functions. VIP promotes neuronal survival during development and apoptotic challenges. Further, VIP has been shown to regulate hormonal release, circadian rhythms, vasodilation, and T cell proliferation in central and peripheral tissues. VIP binds with equally high affinity to VPAC1 and VPAC2 receptors, members of the Class B family of G protein-coupled receptors (GPCRs) that also include the PAC1, glucagon (GCGR), and CRH receptors. VIP binding has previously been shown to increase downstream MAPK signaling cascades, especially MEK/ERK. Given the structural similarities and functional overlap between VPAC1 and VPAC2 receptors, we sought to investigate whether there are small molecule modulators that can probe and identify the functional distinctions between the two receptor subtypes. For these studies, we used HEK-293 cells stably expressing the VPAC1-EGFP or the VPAC2-EGFP receptor. The cultures

Research proves that aside from treating medical problems related to cardiovascular and respiratory system, Coleus forskohlii helps in increasing the production and secretion of thyroid hormones.Derived from the root portion of a plant known by the name of Plectranthus barbatus, the herb contains a chemical called Forsholin which stimulates a series of chemical reactions involving cAMP, causing energy release from the fat cells. Its action is similar to ephedrine but fortunately, the side effects associated with ephedrine are bypassed while using this particular medicinal herb.. To improve the sluggish working of the thyroid gland as well as torch fat (fat increases in a hypothyroid state), a dose of 50-100 mg of Coleus, taken two to three times in a day is enough. Those having medications such as warfarin or aspirin (anticoagulants) must speak to their physician before including the herb in their treatment regime. As it has a tendency to reduce blood pressure, people on anti-hypertensive drugs ...

We compare recent quantum mechanical computations of alternative reaction pathways for carboxypeptidase A, a zinc proteinase, in an "enzyme environment" to similar calculations in the "gas phase" that include the minimal chemical entities that are required for a non-catalytic reaction. The main question that we address is whether anything may be learned from such reduced representations. Two general acid-general base alternative pathways and one nucleophilic pathway are compared. The original calculations were run on a relatively large model (120 atoms) of the active site of carboxypeptidase A which included zinc and its ligands, as well as the residues Arg145, Arg127, Glu270, a water molecule and a model dipeptide. The "gas-phase" pathways include only the dipeptide, water and Glu270 and serve as models for the non-catalytic pathway. The calculations were performed by semiempirical MNDO/H/d that includes modifications for d-orbital representations as well as for intra- and intermolecular ...

The abdominal organs ares kept in place within the large abdominal cavity by a combination of overlying layers of tissue (peritoneum) and ligaments. Neighboring organs also support each other along with fat tissue. Although the organs can move to some extent, the supporting structures ensure that any movement of an individual organ is minimal. Twisting of the abdominal organs is uncommon but can occur with very long structures like the intestines (intestinal volvulus or twisted bowel). The gallbladder can also twist along the long axis on its pedicle.. The mesentery is a sheet of tissue that contains within it the arteries and veins that carry blood to and from the intestines. It also supports and supplies surrounding organs like the gallbladder. When there are anatomic variants in the mesentery or loss of visceral fat (fat tissue around the organs) then the gallbladder is free to move around more than it normally should. This is freely hanging gallbladder is also referred to as a "floating ...
Method of Action. Zinc is an important metallic constituent of the enzyme carboxypeptidase A, a pancreatic enzyme active in protein degradation. Zinc is found in highest concentration in the liver, with lesser amounts found in the pancreas, kidney, and pituitary gland. Zinc absorption occurs primarily in the small intestine. Zinc-binding ligand molecules act to transport zinc across the mucosal cells of the intestine, where it is picked up by albumin molecules for transport to the liver and other organs.. Zinc is a constituent of the enzyme carbonic anhydrase. This enzyme is, in turn, a constituent of red blood cells and gastric juices, and plays an important role in the deposition of calcium salts in teeth and bones.. The enzyme alcohol dehydrogenase contains zinc and is essential for the conversion of alcohol to an aldehyde, thereby facilitating alcohol metabolism in the liver. The function of this enzyme and its relationship to the development of liver cirrhosis is conspicuously tied to ...

From NCBI Gene:. This gene encodes a secreted glycoprotein that belongs to the semaphorin class 3 family of neuronal guidance cues. The encoded protein contains an N-terminal sema domain, integrin and immunoglobulin-like domains, and a C-terminal basic domain. Homodimerization and proteolytic cleavage of the C-terminal propeptide are necessary for the function of the encoded protein. It binds a neuropilin co-receptor before forming a heterotrimeric complex with an associated plexin. An increase in the expression of this gene correlates with an increase in cancer cell invasion and adhesion. Naturally occurring mutations in this gene are associated with Hirschsprung disease.

Both decreased Si determined by the euglycemic insulin clamp and decreased EIR were predictors of type 2 diabetes in the multivariate analysis in this elderly male population, as has been shown previously in young Pima Indians (6). Furthermore, in the present study, the propeptides 32-33 split proinsulin and intact proinsulin significantly predicted conversion to type 2 diabetes over a 7-year follow-up, also after adjustments for the EIR and Si determined by the gold standard euglycemic insulin clamp.. Hyperproinsulinemia can be a consequence of a primary reduction of insulin secretion capacity. An increased proportion of proinsulin in secretory granules at the time of exocytosis may reflect a slower rate of conversion from proinsulin to insulin (26). It is assumed that the packaging of proinsulin and proinsulin conversion enzymes into the nascent secretory granules depends on an active sorting process (27), but studies on the specificity of the sorting process in the regulated secretory pathway ...

Lately, we have identified two polypeptides of 92-94 kDa (GRL1) and 45-60 kDa (GRL2), expressed in cytoplasmic granules of chicken granulocytes and thrombocytes. Here, we report that GRL1 and GRL2 are widely distributed in all exocrine and several endocrine cell types, but not in neurons of the central nervous system, during late stages of embryonic development, as well as in newly hatched and two-month-old chickens. Immunogold studies in ultrathin frozen sections of pancreatic acinar cells show that GRL1 and GRL2 are co-localized at the periphery of zymogen granules, in granules fused with apical acinar membranes and on apical membranes of acini, while the pregranular compartments of the secretory pathway are weakly or not labeled. Semiquantitative morphometric studies indicate that GRL1 and GRL2 are equally distributed in secretory granules. A variety of physical and metabolic studies reveal that GRL2, a highly N-glycosylated polypeptide, is an intrinsic membrane protein, while GRL1 is a ...
