Origin of gene overlap: the case of TCP1 and ACAT2. (1/158)

The human acetyl-CoA acetyltransferase 2 gene, ACAT2, codes for a thiolase, an enzyme involved in lipid metabolism. The human T-complex protein 1 gene, TCP1, encodes a molecular chaperone of the chaperonin family. The two genes overlap by their 3'-untranslated regions, their coding sequences being located on opposite DNA strands in a tail-to-tail orientation. To find out how the overlap might have arisen in evolution, the homologous genes of the zebrafish, the African toad, caiman, platypus, opossum, and wallaby were identified. In each species, standard or long polymerase chain reactions were used to determine whether the ACAT2 and TCP1 homologs are closely linked and, if so, whether they overlap. The results reveal that the overlap apparently arose during the transition from therapsid reptiles to mammals and has been retained for >200 million years. Part of the overlapping untranslated region shows remarkable sequence conservation. The overlap presumably arose during the chromosomal rearrangement that brought the two unrelated and previously separated genes together. One or both of the transposed genes found by chance signals that are necessary for the processing of their transcripts to be present on the noncoding strand of the partner gene.  (+info)

Disassembly of the cytosolic chaperonin in mammalian cell extracts at intracellular levels of K+ and ATP. (2/158)

The eukaryotic, cytoplasmic chaperonin, CCT, is essential for the biogenesis of actin- and tubulin-based cytoskeletal structures. CCT purifies as a doubly toroidal particle containing two eight-membered rings of approximately 60-kDa ATPase subunits, each encoded by an essential and highly conserved gene. However, immunofluorescence detection with subunit-specific antibodies has indicated that in cells CCT subunits do not always co-localize. We report here that CCT ATPase activity is highly dependent on K+ ion concentration and that in cell extracts, at physiological levels of K+ and ATP, there is considerable dissociation of CCT to a smaller oligomeric structure and free subunits. This dissociation is consequent to ATP hydrolysis and is readily reversed on removal of ATP. The ranking order for ease with which subunits can exit the chaperonin particle correlates well with the length of a loop structure, identified by homology modeling, in the intermediate domain of CCT subunits. K+-ATP-induced disassembly is not an intrinsic property of purified CCT over a 40-fold concentration range and requires the presence of additional factor(s) present in cell extracts.  (+info)

Structure of Tetrahymena CCT theta gene and its expression under colchicine treatment. (3/158)

We report here the cloning and the characterization of the Tetrahymena pyriformis chaperonin-containing-TCP1 theta gene (TpCCT theta), an orthologue of the mouse chaperonin gene CCT theta. TpCCT theta gene is interrupted by eight introns, ranging in size between 91 and 419 nucleotides, and encodes a protein consisting of 540 amino acid residues (59.1 kDa), with a putative pI of 5.73. The amino acid sequence of TpCCT theta reveals 39.4-46.0% identity with the sequences of Candida albicans and mouse CCT theta subunits and 28.0-32.6% identity with the other TpCCT subunits known so far. We have studied the expression of this gene in exponentially growing Tetrahymena cells and in cells treated with colchicine for different times. The steady-state levels of CCT theta mRNA rapidly decrease in the first 30 min of colchicine treatment. Interestingly, treatment for subsequent 60 min gives expression levels higher than those found in exponentially growing cells.  (+info)

Transcriptional activation of mouse cytosolic chaperonin CCT subunit genes by heat shock factors HSF1 and HSF2. (4/158)

The chaperonin containing TCP-1 (CCT) is a eukaryotic molecular chaperone consisting of eight subunit species and assists in the folding of cytosolic proteins. We show here that all eight mouse CCT subunit genes contain sequences called heat shock elements for binding heat shock transcription factors (HSFs) by electrophoretic mobility shift assays and that these genes are transcriptionally activated by HSFs in reporter gene assays using HeLa cells transiently overexpressing HSFs. These results suggest that HSF1 and/or HSF2 play a role in Cct gene expression.  (+info)

Cytosolic chaperonin is up-regulated during cell growth. Preferential expression and binding to tubulin at G(1)/S transition through early S phase. (5/158)

The chaperonin containing t-complex polypeptide 1 (CCT) is a heterooligomeric molecular chaperone assisting in the folding of actin, tubulin, and other cytosolic proteins. The expression levels of CCT subunits varied among seven mouse cell lines tested but showed a close correlation with growth rate. Both the CCT protein and mRNA levels in the human promyelolytic cell HL60 decreased concomitant with growth arrest during differentiation. More rapid decrease in CCT level occurred when the mouse interleukin (IL)-3-dependent myeloid DA3 cells were starved for IL-3. Readdition of IL-3 caused rapid resumption of CCT synthesis during synchronous growth: the maximum CCT protein and mRNA levels were observed at G(1)/S transition through early S phase. The turnover rate of CCT was nearly constant regardless of growth. Gel filtration and immunoprecipitation analyses indicated that CCT in vivo is associated with tubulin at early S phase, but not at G(0)/G(1) phase. These results demonstrated that CCT expression is strongly up-regulated during cell growth especially from G(1)/S transition to early S phase and is primarily controlled at the mRNA level. CCT appears to play important roles for cell growth by assisting in the folding of tubulin and other proteins.  (+info)

Partial occlusion of both cavities of the eukaryotic chaperonin with antibody has no effect upon the rates of beta-actin or alpha-tubulin folding. (6/158)

The eukaryotic chaperonin containing T-complex polypeptide 1 (CCT) is required in vivo for the production of native actin and tubulin. It is a 900-kDa oligomer formed from two back-to-back rings, each containing eight different subunits surrounding a central cavity in which interactions with substrates are thought to occur. Here, we show that a monoclonal antibody recognizing the C terminus of the CCTalpha subunit can bind inside, and partially occlude, both cavities of apo-CCT. Rabbit reticulocyte lysate was programmed to synthesize beta-actin and alpha-tubulin in the presence and absence of anti-CCTalpha antibody. The binding of the antibody inside the cavity and its occupancy of a large part of it does not prevent the folding of beta-actin and alpha-tubulin by CCT, despite the fact that all the CCT in the in vitro translation reactions was continuously bound by two antibody molecules. Furthermore, no differences in the protease susceptibility of actin bound to CCT in the presence and absence of the monoclonal antibody were detected, indicating that the antibody molecules do not perturb the conformation of actin folding intermediates substantially. These data indicate that complete sequestration of substrate by CCT may not be required for productive folding, suggesting that there are differences in its folding mechanism compared with the Group I chaperonins.  (+info)

Upregulation of cytosolic chaperonin CCT subunits during recovery from chemical stress that causes accumulation of unfolded proteins. (7/158)

The chaperonin containing TCP-1 (CCT) is a molecular chaperone consisting of eight subunit species and assists in the folding of actin, tubulin and some other cytosolic proteins. We examined the stress response of CCT subunit proteins in mammalian cultured cells using chemical stressors that cause accumulation of unfolded proteins. Levels of CCT subunit proteins in HeLa cells were coordinately and transiently upregulated under continuous chemical stress with sodium arsenite. CCT subunit levels in several mammalian cell lines were also upregulated during recovery from chemical stress caused by sodium arsenite or a proline analogue, L-azetidine-2-carboxylic acid. Several unidentified proteins that were newly synthesized and associated with CCT were found to increase concomitantly with CCT subunits themselves and known substrates during recovery from the stress. These results suggest that CCT plays important roles in the recovery of cells from protein damage by assisting in the folding of proteins that are actively synthesized and/or renatured during this period.  (+info)

Individual subunits of the eukaryotic cytosolic chaperonin mediate interactions with binding sites located on subdomains of beta-actin. (8/158)

The chaperonin containing TCP-1 (CCT) of eukaryotic cytosol is composed of eight different subunit species that are proposed to have independent functions in folding its in vivo substrates, the actins and tubulins. CCT has been loaded with (35)S-beta-actin by in vitro translation in reticulocyte lysate and then subjected to immunoprecipitation with all eight anti-CCT subunit antibodies in mixed micelle buffers, conditions that disrupt CCT into its constituent monomers. Interactions between (35)S-beta-actin and isolated CCTalpha, CCTbeta, CCTepsilon, or CCTtheta subunits are observed, suggesting that polar and electrostatic interactions may mediate actin binding to these four CCT subunits. Additionally, a beta-actin peptide array was screened for CCT-binding sequences. Three regions rich in charged and polar amino acid residues, which map to the surface of native beta-actin, are implicated in interactions between actin and CCT. Several of these biochemical results are consistent with the recent cryo-electron microscopy three-dimensional structure of apo-CCT-alpha-actin, in which alpha-actin is bound by the apical domains of specific CCT subunits. A model is proposed in which actin interacts with several CCT subunits during its CCT-mediated folding cycle.  (+info)

Component of the chaperonin-containing T-complex (TRiC), a molecular chaperone complex that assists the folding of proteins upon ATP hydrolysis.
The substrate recognition mechanisms in chaperonins Chaperonins are a family of proteins devoted to assisting the folding of other proteins. They are large oligomers assembled into ring structures that enclose a cavity in which folding takes place. For this process to occur, the chaperonin must first recognize and interact with the unfolded polypeptide, then undergo a conformational change upon nucleotide binding that results in the closure of the cavity which in turn mediates the folding reaction inside the cavity. Although this general mechanism seems to apply to every chaperonin studied so far, there exist two different modes of interaction between the chaperonin and the substrate. The first occurs mainly through the interaction between the exposed hydrophobic residues of the unfolded polypeptides and those of the chaperonin substrate binding site, as elucidated for the chaperonin GroEL from E. coli. The second type of mechanism has been described so far only for the cytosolic chaperonin CCT ...

Here, we study and compare the mechanisms of action of the GroEL/GroES and the TRiC chaperonin systems on MreB client protein variants extracted from E. coli. MreB is a homologue to actin in prokaryotes. Single-molecule fluorescence correlation spectroscopy (FCS) and time-resolved fluorescence polarization anisotropy report the binding interaction of folding MreB with GroEL, GroES and TRiC. Fluorescence resonance energy transfer (FRET) measurements on MreB variants quantified molecular distance changes occurring during conformational rearrangements within folding MreB bound to chaperonins. We observed that the MreB structure is rearranged by a binding-induced expansion mechanism in TRiC, GroEL and GroES. These results are quantitatively comparable to the structural rearrangements found during the interaction of beta-actin with GroEL and TRiC, indicating that the mechanism of chaperonins is conserved during evolution. The chaperonin-bound MreB is also significantly compacted after addition of ...

Actin requires the chaperonin containing TCP1 (CCT), a hexadecameric ATPase essential for cell viability in eukaryotes, to fold to its native state. Following binding of unfolded actin to CCT, the cavity of the chaperone closes and actin is folded and released in an ATP-dependent folding cycle. In yeast, CCT forms a ternary complex with the phosducin-like protein PLP2p to fold actin, and together they can return nascent or chemically denatured actin to its native state in a pure in vitro folding assay. The complexity of the CCT-actin system makes the study of the actin folding mechanism technically challenging. We have established a novel spectroscopic assay through selectively labeling the C terminus of yeast actin with acrylodan and observe significant changes in the acrylodan fluorescence emission spectrum as actin is chemically unfolded and then refolded by the chaperonin. The variation in the polarity of the environment surrounding the fluorescent probe during the unfolding/folding ...

The Penticton Vees (14-5-1-2) hit double digits in goals in back to back games for the first time since October 2014 with a 10-1 drubbing of the Cowichan Valley Capitals (2-18-3-1) Saturday night.. Just 22 seconds into the game a shot from the right point by Ryan OConnell hit Jack Barnes in the skate and deflected past Capitals goalie Adam Marcoux to give the Vees the lead.. Jared Nash set a new career high with his sixth goal of the season to give the Vees a 2-0 lead just four minutes later after tapping in a centring feed from Taylor Ward.. Not long after, the Vees were hit with back-to-back unsportsmanlike penalties, putting them down two men. Ty Pochipinski scored with just one second remaining in the five on three to cut the lead down to 2-1.. Nash was clipped with a high stick off a face-off in the attacking zone that went undetected by the officials. Vees head coach Fred Harbinson voiced his displeasure and was ejected from the game..

1) The Sixers led by just three points after the first quarter, but the Knicks came out freezing cold in the second, shooting 1-of-11 from the floor to start the quarter. The Knicks fought back, though, tying the game 45-45 with two and a half minutes left in the first half. The Sixers finished the first half strong, winding up with a 52-46 lead at the break. The Knicks shot just 40.5 percent as a team and turned the ball over 10 times in the half.. Both teams came out sloppy in the second half, but the Knicks outscored the Sixers 23-18 in the frame, and trailed by just one point entering the fourth quarter. With four minutes to go in the game, the Sixers maintained an 84-81 lead. With just under two minutes to go, a Mitchell Robinson dunk cut the Sixers lead to just one point.. In the final minute.

Next was at the top of the aptly named Vomit Hill, which is not terribly long but is ridiculously steep. When I reached the top, I was certain I was hallucinating; I had to take a video to confirm there was a woman playing a trumpet and offering riders donuts and PBR. And if you also dont believe me, heres the video to prove it.. The next bright spot was riding up Keystone road, where the pedals seemed to turn over easily. That lasted about 20 minutes, until I picked up an anchor, hugged it, and threw it overboard, dragging it all the way to the line. I dont think the small portion of donut I ate helped my situation, but I also believe my low energy was a result of being slightly underfed, under-slept and under-watered from the previous day. Thus, Ive eaten more, slept more and consumed more fluids today in an attempt to help my general well being..

What are the implications of the CCT-mediated actin folding mechanism for the structure and function of F-actin? Reisler & Egelman (2007) have collated many disparate observations concerning biochemical and structural properties of F-actin and argued convincingly that F-actin should not be considered to be a single state but rather a dynamic ensemble of many states. Transitions between states are probably coupled to rotations and tilts of subunits, which occur readily despite the apparently severe structural constraint of a constant axial rise of every subunit in the filament of approximately 27.3 Å. Put succinctly, in its breathing modes F-actin changes its shape more than its length.. The emerging view of time-correlated motions and protein function is that active enzymatic or ligand-binding states reflect configurations that pre-exist in the ensemble. In adenylate kinase, the catalytically competent closed state is occasionally sampled on microseconds-milliseconds time scales even in the ...

Trimeric intracellular cation-selective (TRIC) channel subtypes, namely TRIC-A and TRIC-B, are derived from distinct genes and distributed throughout the sarco/endoplasmic reticulum (SR/ER) and nuclear membranes. TRIC-A is preferentially expressed at high levels in excitable tissues, while TRIC-B is ubiquitously detected at relatively low levels in various tissues. TRIC channels are composed of ~300 amino acid residues and contain three putative membrane-spanning segments to form a bullet-shaped homo-trimeric assembly. Both native and purified recombinant TRIC subtypes form functional monovalent cation-selective channels in a lipid bilayer reconstitution system. The electrophysiological data indicate that TRIC channels behave as K(+) channels under intracellular conditions, although the detailed channel characteristics remain to be investigated. The pathophysiological defects detected in knockout mice suggest that TRIC channels support SR/ER Ca(2+) release mediated by ryanodine (RyR) and inositol

A method for packaging integrated circuit chips (die) is described that includes providing a base substrate with package level contacts, coating a base substrate with adhesive, placing dies on the adhesive, electrically connecting the die to the package level contacts, and removing the backside of the base substrate to expose the backside of the package level contacts. Accordingly, an essentially true chip scale package is formed. Multi-chip modules are formed by filling gaps between the chips with an encapsulant. In an embodiment, chips are interconnected by electrical connections between package level contacts in the base substrate. In an embodiment, substrates each having chips are adhered back-to-back with through vias formed in aligned saw streets to interconnect the back-to-back chip assembly.
What about protein? The idea behind fueling with a balanced mix of carbohydrates, fat, and protein is to increase the calorie intake while also increasing the nutrient intake. Not only will you be providing glycogen storage, but you will also help to replenish any torn muscle tissue and fatigue the following day. These meals may not be super high in calories, but the balance provides satiation and likely you will only need low-calorie, quick-burning energy for a backup.. I mostly use this method when training for a triathlon with back-to-back-to-back training blocks. Example foods: Protein bars, energy bars, trail mixes with equal balances of nuts, fruit, oats. Smoothies, or full balanced meals. How to use: Before a medium or long workout, particularly between back-to-back sessions or a high-intensity race effort.. When to Use: Best 1-3 hours before a workout over 90 minutes, and every 2 hours throughout your workout. Also right after a workout for recovery or between back-to-back efforts. Best ...

Recently, back-to-back bouts with two distinct flu viruses have managed to take hold of my habitual energy and squash it into a tiny, nearly non-existent ball of fluff. And as I was prostrated, I thought about how the body heals itself. And that, of course, led me to a favorite topic: the brain and its role in healing the heart and the emotions..

She was depressed, sad, and over-weight from stuffing herself with sugary products in a blind attempt to comfort eat her way to feeling better about herself. Recently out of a failed marriage that had eked away at her already low self-regard, she believed she was worthless and useless, despite rather amazing artistic abilities that I came to know more closely over time. She cried a lot during those early sessions.. Albert* came some years after Rachel, and was also plagued by deep feelings of lacking in self-esteem. He was just short of ...

The adage of Easy-Hard is often applied to weekly training. Run easy one day, then do speedwork (very roughly, we could lump them all: tempo, interval, fartlek) the next. The Easy-Hard principle makes good sense. I think it can also be applied to back-to-back long runs, too. Just because a 5 hour run is done at an easy pace does not mean its an easy run. It needs to be put in context. If you run 4 hour runs all the time, maybe it is indeed easy. And if the day before and day after you run 10 or 15km (or not at all), maybe it is indeed easy. But if you run a 4 hour run and then wake up the next day to run another 4 hour run, can that second run REALLY be called easy? Only if it really feels bloody easy to you - and not to anyone else or any programs advice. That second run might really be a hard run ...
