A heterotrimeric GTP-binding protein that mediates the light activation signal from photolyzed rhodopsin to cyclic GMP phosphodiesterase and is pivotal in the visual excitation process. Activation of rhodopsin on the outer membrane of rod and cone cells causes GTP to bind to transducin followed by dissociation of the alpha subunit-GTP complex from the beta/gamma subunits of transducin. The alpha subunit-GTP complex activates the cyclic GMP phosphodiesterase which catalyzes the hydrolysis of cyclic GMP to 5'-GMP. This leads to closure of the sodium and calcium channels and therefore hyperpolarization of the rod cells. EC 3.6.1.-.

The human F box protein beta-Trcp associates with the Cul1/Skp1 complex and regulates the stability of beta-catenin. (1/185)

Ubiquitin-conjugation targets numerous cellular regulators for proteasome-mediated degradation. Thus, the identification of ubiquitin ligases and their physiological substrates is crucially important, especially for those cases in which aberrant levels of regulatory proteins (e.g., beta-catenin, p27) result from a deregulated ubiquitination pathway. In yeast, the proteolysis of several G1 regulators is controlled by ubiquitin ligases (or SCFs) formed by three subunits: Skp1, Cul A (Cdc53), and one of many F-box proteins. Specific F-box proteins (Fbps) recruit different substrates to the SCF. Although many Fbps have been identified in mammals, their specific substrates and the existence of multiple SCFs have not yet been reported. We have found that one human Fbp, beta-Trcp (beta-Transducin repeat containing protein), does indeed form a novel SCF with human Skp1 and Cul1. Consistent with recent reports indicating that Xenopus and Drosophila beta-Trcp homologs act as negative regulators of the Wnt/beta-catenin signaling pathway, we report here that human beta-Trcp interacts with beta-catenin in vivo. Furthermore, beta-catenin is specifically stabilized in vivo by the expression of a dominant negative beta-Trcp. These results indicate that the Cul1/Skp1/beta-Trcp complex forms a ubiquitin ligase that mediates the degradation of beta-catenin.  (+info)

The F-box protein beta-TrCP associates with phosphorylated beta-catenin and regulates its activity in the cell. (2/185)

Defects in beta-catenin regulation contribute to the neoplastic transformation of mammalian cells. Dysregulation of beta-catenin can result from missense mutations that affect critical sites of phosphorylation by glycogen synthase kinase 3beta (GSK3beta). Given that phosphorylation can regulate targeted degradation of beta-catenin by the proteasome, beta-catenin might interact with an E3 ubiquitin ligase complex containing an F-box protein, as is the case for certain cell cycle regulators. Accordingly, disruption of the Drosophila F-box protein Slimb upregulates the beta-catenin homolog Armadillo. We reasoned that the human homologs of Slimb - beta-TrCP and its isoform beta-TrCP2 (KIAA0696) - might interact with beta-catenin. We found that the binding of beta-TrCP to beta-catenin was direct and dependent upon the WD40 repeat sequences in beta-TrCP and on phosphorylation of the GSK3beta sites in beta-catenin. Endogenous beta-catenin and beta-TrCP could be coimmunoprecipitated from mammalian cells. Overexpression of wild-type beta-TrCP in mammalian cells promoted the downregulation of beta-catenin, whereas overexpression of a dominant-negative deletion mutant upregulated beta-catenin protein levels and activated signaling dependent on the transcription factor Tcf. In contrast, beta-TrCP2 did not associate with beta-catenin. We conclude that beta-TrCP is a component of an E3 ubiquitin ligase that is responsible for the targeted degradation of phosphorylated beta-catenin.  (+info)

Inducible degradation of IkappaBalpha by the proteasome requires interaction with the F-box protein h-betaTrCP. (3/185)

Activation of NF-kappaB transcription factors requires phosphorylation and ubiquitin-proteasome-dependent degradation of IkappaB proteins. We provide evidence that a human F-box protein, h-betaTrCP, a component of Skp1-Cullin-F-box protein (SCF) complexes, a new class of E3 ubiquitin ligases, is essential for inducible degradation of IkappaBalpha. betaTrCP associates with Ser32-Ser36 phosphorylated, but not with unmodified IkappaBalpha or Ser32-Ser36 phosphorylation-deficient mutants. Expression of a F-box-deleted betaTrCP inhibits IkappaBalpha degradation, promotes accumulation of phosphorylated Ser32-Ser36 IkappaBalpha, and prevents NF-kappaB-dependent transcription. Our findings indicate that betaTrCP is the adaptor protein required for IkappaBalpha recognition by the SCFbetaTrCP E3 complex that ubiquitinates IkappaBalpha and makes it a substrate for the proteasome.  (+info)

Negative regulation of axis formation and Wnt signaling in Xenopus embryos by the F-box/WD40 protein beta TrCP. (4/185)

Screening a maternal Xenopus expression library for activities that synergize with low levels of injected beta-catenin, we have isolated a clone encoding the C-terminal end of x-beta TrCP-2, a highly conserved protein belonging to the F-box/WD40 family of ubiquitin-ligase specificity factors. We show that x-beta TrCP-2 expression reduces dorsal axis formation in Xenopus embryos. A dominant negative mutant lacking the F-box triggers the opposite effect, inducing secondary axes and activating the expression of Wnt responsive genes in ectodermal explants. In light of the existence of beta TrCP transcripts associated with the vegetal cortex, we propose that beta TrCP plays a fundamental role in the establishment of the dorsal determinants during cortical rotation in Xenopus.  (+info)

An F-box protein, FWD1, mediates ubiquitin-dependent proteolysis of beta-catenin. (5/185)

beta-catenin plays an essential role in the Wingless/Wnt signaling cascade and is a component of the cadherin cell adhesion complex. Deregulation of beta-catenin accumulation as a result of mutations in adenomatous polyposis coli (APC) tumor suppressor protein is believed to initiate colorectal neoplasia. beta-catenin levels are regulated by the ubiquitin-dependent proteolysis system and beta-catenin ubiquitination is preceded by phosphorylation of its N-terminal region by the glycogen synthase kinase-3beta (GSK-3beta)/Axin kinase complex. Here we show that FWD1 (the mouse homologue of Slimb/betaTrCP), an F-box/WD40-repeat protein, specifically formed a multi-molecular complex with beta-catenin, Axin, GSK-3beta and APC. Mutations at the signal-induced phosphorylation site of beta-catenin inhibited its association with FWD1. FWD1 facilitated ubiquitination and promoted degradation of beta-catenin, resulting in reduced cytoplasmic beta-catenin levels. In contrast, a dominant-negative mutant form of FWD1 inhibited the ubiquitination process and stabilized beta-catenin. These results suggest that the Skp1/Cullin/F-box protein FWD1 (SCFFWD1)-ubiquitin ligase complex is involved in beta-catenin ubiquitination and that FWD1 serves as an intracellular receptor for phosphorylated beta-catenin. FWD1 also links the phosphorylation machinery to the ubiquitin-proteasome pathway to ensure prompt and efficient proteolysis of beta-catenin in response to external signals. SCFFWD1 may be critical for tumor development and suppression through regulation of beta-catenin protein stability.  (+info)

HOS, a human homolog of Slimb, forms an SCF complex with Skp1 and Cullin1 and targets the phosphorylation-dependent degradation of IkappaB and beta-catenin. (6/185)

SCF E3 ubiquitin ligases mediate ubiquitination and proteasome-dependent degradation of phosphorylated substrates. We identified a human F-box/WD40 repeats protein (HOS), which is homologous to Slimb/h betaTrCP. Being a part of SCF complex with Skp1 and Cullin1, HOS specifically interacted with the phosphorylated IkappaB and beta-catenin, targeting these proteins for proteasome-dependent degradation in vivo. This targeting required Cullin1 as expression of a mutant Cullin1 abrogated the degradation of IkappaB and of beta-catenin. Mutant HOS which lacks the F-box blocked TNF alpha-induced degradation of IkappaB as well as GSK3beta-mediated degradation of beta-catenin. This mutant also inhibited NF-kappaB transactivation and increased the beta-catenin-dependent transcription activity of Tcf. These results demonstrate that SCF(HOS) E3 ubiquitin ligase regulate both NF-kappaB and beta-catenin signaling pathways.  (+info)

beta-Trcp couples beta-catenin phosphorylation-degradation and regulates Xenopus axis formation. (7/185)

Regulation of beta-catenin stability is essential for Wnt signal transduction during development and tumorigenesis. It is well known that serine-phosphorylation of beta-catenin by the Axin-glycogen synthase kinase (GSK)-3beta complex targets beta-catenin for ubiquitination-degradation, and mutations at critical phosphoserine residues stabilize beta-catenin and cause human cancers. How beta-catenin phosphorylation results in its degradation is undefined. Here we show that phosphorylated beta-catenin is specifically recognized by beta-Trcp, an F-box/WD40-repeat protein that also associates with Skp1, an essential component of the ubiquitination apparatus. beta-catenin harboring mutations at the critical phosphoserine residues escapes recognition by beta-Trcp, thus providing a molecular explanation for why these mutations cause beta-catenin accumulation that leads to cancer. Inhibition of endogenous beta-Trcp function by a dominant negative mutant stabilizes beta-catenin, activates Wnt/beta-catenin signaling, and induces axis formation in Xenopus embryos. Therefore, beta-Trcp plays a central role in recruiting phosphorylated beta-catenin for degradation and in dorsoventral patterning of the Xenopus embryo.  (+info)

A complex containing betaTrCP recruits Cdc34 to catalyse ubiquitination of IkappaBalpha. (8/185)

Activation of transcription factor NF-kappaB is accomplished by degradation of its inhibitor IkappaBalpha. Signal induced phosphorylation of IkappaBalpha on serine 32 and 36 targets the protein for ubiquitination on lysine 21 and 22. Here we use a phosphorylated peptide substrate representing residues 20-43 of IkappaBalpha to investigate requirements for ubiquitination of IkappaBalpha. Phosphorylation dependent polyubiquitination is carried out by a multiprotein complex containing betaTrCP, Skp1 and Cdc53 (Cull). In the presence of ubiquitin activating enzyme and the protein complex containing betaTrCP, polyubiquitination of IkappaBalpha peptide was dependent on the presence of Cdc34, while Ubc5 only stimulated mono- and di-ubiquitination.  (+info)

Ubiquitin-dependent degradation of hormone receptors is emerging as a key mechanism that regulates the magnitude and duration of hormonal effects on cells and tissues. The pituitary hormone prolactin (PRL) is involved in regulating cell differentiation, proliferation, and survival. PRL engages its receptor (PRLR) to initiate various signaling cascades, including the phosphorylation and activation of Stat5. We found that PRL promotes interaction between PRLR and the F-box protein beta-TrCP2, which functions as a substrate recognition subunit of the SCF(beta-TrCP) E3 ubiquitin ligase. This interaction requires PRLR phosphorylation and the integrity of serine 349 within a conserved motif, which is similar to conserved motifs present in other substrates of SCF(beta-TrCP). The PRLR(S349A) mutant is resistant to ubiquitination and is more stable than its wild-type counterpart. Phosphorylated PRLR undergoes ubiquitination by SCF(beta-TrCP) in vitro. Knockdown of beta-TrCP expression inhibits the ubiquitination

WD40 domain is one of the most abundant domains and is one of the most active domains of the eukaryotes. Their functions are deeply involved in cellular processes by playing a crucial role as hubs in cellular networks. WD40 Domain regulates diverse protein-protein interactions, especially those that scaffold. They are present in processes such as signal transduction, cell division, chemotaxis, RNA processing, and cytoskeleton construction. WD40 domains were first discovered in bovine beta-transducin, a subunit of the trimeric G protein transducin complex. It contains a series of sequence of approximately 44-60 residues with folds into seven-bladed beta-propellers. Each blade is designed in a four-stranded anti-parallel beta-sheet. WD40 is naturally exploited as seemingly more suitable than other domain candidates because it structurally more compelling. This means that WD40 domains form structures that are highly symmetrical in comparison to other domains that are involved in intracellular ...

miR-302/367/LATS2/YAP Pathway Is Essential for Prostate Tumor-Propagating Cells and Promotes the Development of Castration Resistance Researchers report that the miR-302/367 cluster, a previously identified potent pluripotency regulator, is upregulated in prostate tumors. The forced expression of the miR-302/367 cluster accelerated the in vitro and in vivo growth of prostate cancer (PCa) cells and their resistance to androgen ablation, whereas the knockdown of the miR-302/367 cluster using anti-sense RNA suppressed the incidence of formation, growth rate and endpoint weight of PCa cell tumors.

The transcription factor NF-E2-related factor 2 (Nrf2) is a master regulator of a genetic program, termed the phase 2 response, that controls redox homeostasis and participates in multiple aspects of physiology and pathology. Nrf2 protein stability is regulated by two E3 ubiquitin ligase adaptors, Keap1 and ß-TrCP, the latter of which was only recently reported. Here, two-dimensional (2D) gel electrophoresis and site-directed mutagenesis allowed us to identify two serines of Nrf2 that are phosphorylated by glycogen synthase kinase 3ß (GSK-3ß) in the sequence DSGISL. Nuclear magnetic resonance studies defined key residues of this phosphosequence involved in docking to the WD40 propeller of ß-TrCP, through electrostatic and hydrophobic interactions. We also identified three arginine residues of ß-TrCP that participate in Nrf2 docking. Intraperitoneal injection of the GSK-3 inhibitor SB216763 led to increased Nrf2 and heme oxygenase-1 levels in liver and hippocampus. Moreover, mice with ...

A abóbora é uma hortaliça que apresenta grande importância na agricultura familiar no nordeste brasileiro. Muitas comunidades têm encontrado dificuldades na comercialização de todos os frutos produzidos, em função da grande variabilidade fenotípica, que nem sempre atende às exigências do mercado. O estudo de parâmetros genéticos é importante para fornecer informações na implantação e condução de um programa de melhoramento. Desta forma, o objetivo do trabalho foi estimar parâmetros genéticos, fenotípicos e ambientais para caracteres morfológicos e agronômicos em abóbora. Foram estudados sete genótipos de abóbora para os anos agrícolas de 2008 e 2009, considerando como aleatório o efeito dos anos e fixo o efeito dos genótipos. As variáveis analisadas foram comprimento e largura do fruto, espessura da polpa na região do pedúnculo, do meio e da parte inferior do fruto, altura e largura da cavidade interna do fruto, rendimento de frutos, número de sementes por ...

OK, Tahiti and Bora Bora are stunningly beautiful. Hope you get the chance to go there.

  • Heterotrimeric guanine nucleotide-binding proteins (G proteins), which integrate signals between receptors and effector proteins, are composed of an alpha, a beta, and a gamma subunit. (genecards.org)
  • Heterotrimeric guanine nucleotide-binding proteins (G proteins), which integrate signals between. (biomol.com)
  • p>When browsing through different UniProt proteins, you can use the 'basket' to save them, so that you can back to find or analyse them later. (uniprot.org)
  • Synthetic peptide conjugated to KLH derived from within residues 550 to the C-terminus of Human Beta TRCP. (abcam.com)
  • To directly examine whether β-TRCP proteins are required for Plk2-dependent SPAR turnover, we took advantage of a shRNA vector (shβ-TRCP) that is capable of suppressing protein expression of both human β-TRCP1 and β-TRCP2. (nih.gov)
  • These results suggest that mTORC2 regulates the stability of beta-TrCP1 in TNBC cells and targeting beta-TrCP1 is a potential approach to treat human TNBC. (bvsalud.org)
  • Wnt signaling begins with translation and transcription of the 19 human Wnt proteins (Figure 1). (cancerlink.ru)
  • Testing for the beta fraction of human chorionic gonadotropin is the basis for most serum and urine pregnancy tests. (thefreedictionary.com)
  • TBL1Y (ADR83034.1, 1 a.a. ~ 522 a.a) full-length human protein. (abnova.com)
  • The domain co-occurrence network was constructed for the human proteome based on PFAM domains in proteins. (biomedcentral.com)
  • In the absence of these proteins, ribosome biogenesis is stalled and cell growth is terminated even under optimal growth conditions. (genome.jp)
  • The specificity of the proteins is determined by the sequences outside the repeats themselves. (embl.de)
  • Each G protein contains an alpha-, beta- and gamma-subunit and is bound to GDP in the 'off' state. (genecards.org)
  • However, the only studied example of a WD-repeat protein, G beta, synthesized in vitro in a rabbit reticulocyte lysate, is unable to fold into a native structure without its partner protein G gamma. (embl.de)
  • Our working definition of folding was that the proteins from globular, trypsin-resistant structures because, except for G beta gamma, their functions are not known or cannot be assayed in reticulocyte lysates. (embl.de)
  • RGS11 contains a G protein gamma subunit-like (GGL) domain between its Dishevelled/Egl-10/Pleckstrin and RGS domains. (embl-heidelberg.de)
  • Here we demonstrate that Drosophila Spt5 interacts both physically and genetically with the Polycomb Group (PcG) protein Pleiohomeotic (Pho), and the majority of Pho binding sites overlap with Spt5 binding sites across the genome in S2 cells. (brookes.ac.uk)
  • KPNA2 protein interacts with the NLSs of DNA helicase Q1 and SV40 T antigen and may be involved in the nuclear transport of proteins. (cancerindex.org)
  • If WD proteins form structures similar to G beta, their hydrodynamic properties should be those of compact, globular proteins, and they should be resistant to cleavage by trypsin. (embl.de)
  • We show that unlike G beta, several proteins with WD-repeats are able to fold into globular proteins in a rabbit reticulocyte lysate. (embl.de)
  • The two main approaches to the study of protein evolution are the analysis and comparison of sequences of proteins to prove or disprove evolutionary relationships and the other is the simulation of the evolutionary processes computationally in in vitro studies. (wikibooks.org)
  • Both of these tandem repeat sequences were identified at other locations in the chicken genome by Southern blot hybridization. (labome.org)
  • Most of the characterized FBPs are components of the SCF (SKp1, Cullin, F-box protein) E3 ubiquitin-ligase complex. (mdpi.com)
  • Through the cullin 1-Skp1-Fbox E3 ligase complex, the NSs protein promotes the degradation of at least two host proteins, the TFIIH p62 and the PKR proteins. (biomedcentral.com)
  • The SCF (Skp1/Cul1/F-box) ubiquitin ligase recruits phospho-IκBα through the F-box domain-containing adaptor protein, β-TRCP, resulting in the degradation of IκBα, and translocation of the p50/p65 heterodimer into the nucleus [1] , [2] . (prolekare.cz)
  • SCF complex consists of Cullin 1 , SKP1 , F-box proteins (e.g. (bio-rad.com)
  • β-TrCP1 (also known as Fbw1a or FWD1) is the F-box protein component of an Skp1/Cul1/F-box (SCF)-type ubiquitin ligase complex. (pnas.org)
