A family of structurally related proteins that were originally discovered for their role in cell-cycle regulation in CAENORHABDITIS ELEGANS. They play important roles in regulation of the CELL CYCLE and as components of UBIQUITIN-PROTEIN LIGASES.
A family of proteins that are structurally-related to Ubiquitin. Ubiquitins and ubiquitin-like proteins participate in diverse cellular functions, such as protein degradation and HEAT-SHOCK RESPONSE, by conjugation to other proteins.
A subset of ubiquitin protein ligases that are formed by the association of a SKP DOMAIN PROTEIN, a CULLIN DOMAIN PROTEIN and a F-BOX DOMAIN PROTEIN.

Alternate choice of initiation codon produces a biologically active product of the von Hippel Lindau gene with tumor suppressor activity. (1/749)

The VHL tumor suppressor gene has previously been reported to encode a protein of 213 amino acid residues. Here we report the identification of a second major VHL gene product with an apparent molecular weight of 18 kD, pVHL18, which appears to arise from alternate translation initiation at a second AUG codon (codon 54) within the VHL open reading frame. In vitro and in vivo studies indicate that the internal codon in the VHL mRNA is necessary and sufficient for production of pVHL18. pVHL18 can bind to elongin B, elongin C, and Hs-CUL2. When reintroduced into renal carcinoma cells that lack a wild-type VHL allele, pVHL18 suppresses basal levels of VEGF expression, restores hypoxia-inducibility of VEGF expression, and inhibits tumor formation in nude mice. These data strongly support the existence of two distinct VHL gene products in VHL tumor suppression.  (+info)

Cyclin D1 and D3 associate with the SCF complex and are coordinately elevated in breast cancer. (2/749)

D-type cyclins are important cell cycle regulators that promote cellular proliferation in response to growth factors by inactivation of the retinoblastoma protein (Rb). Cyclin D1 has been shown to be overexpressed in several cancer types and to act as an oncogene in breast cancers. As D-type cyclins are rate limiting for progression into S phase, the level at which they accumulate must be carefully regulated. Several mechanisms leading to overexpression of cyclin D1 have been reported including amplification, translocation and stabilization of the mRNA. Here, we present data showing elevated cyclin D1 protein in breast cancer samples in the absence of elevated mRNA level. Further, we found that in these cases, cyclin D3 protein also accumulates and that the coordinate increase in cyclin D1 and D3 occurs in 15% (7/47) of breast cancers. In addition we show that blocking the activity of the 26S proteosome results in the accumulation of cyclin D1 and D3, that both D-type cyclins are ubiquitinated and associate with Cul-1, a component of the SCF ubiquitin ligase complex. Finally, we show that the coordinated elevation of cyclin D1 and D3 is also observed in the breast cell line MCF-7 and demonstrate that the degradation of cyclin D1 and D3 is deficient in this cell line. These results indicate that cyclin D1 and cyclin D3 share a common mechanism of degradation and we propose that the coordinate increase of D-type cyclins observed in primary breast cancers reflects a defect in their proteolysis.  (+info)

Rbx1, a component of the VHL tumor suppressor complex and SCF ubiquitin ligase. (3/749)

The von Hippel-Lindau (VHL) tumor suppressor gene is mutated in most human kidney cancers. The VHL protein is part of a complex that includes Elongin B, Elongin C, and Cullin-2, proteins associated with transcriptional elongation and ubiquitination. Here it is shown that the endogenous VHL complex in rat liver also includes Rbx1, an evolutionarily conserved protein that contains a RING-H2 fingerlike motif and that interacts with Cullins. The yeast homolog of Rbx1 is a subunit and potent activator of the Cdc53-containing SCFCdc4 ubiquitin ligase required for ubiquitination of the cyclin-dependent kinase inhibitor Sic1 and for the G1 to S cell cycle transition. These findings provide a further link between VHL and the cellular ubiquitination machinery.  (+info)

Reconstitution of G1 cyclin ubiquitination with complexes containing SCFGrr1 and Rbx1. (4/749)

Control of cyclin levels is critical for proper cell cycle regulation. In yeast, the stability of the G1 cyclin Cln1 is controlled by phosphorylation-dependent ubiquitination. Here it is shown that this reaction can be reconstituted in vitro with an SCF E3 ubiquitin ligase complex. Phosphorylated Cln1 was ubiquitinated by SCF (Skp1-Cdc53-F-box protein) complexes containing the F-box protein Grr1, Rbx1, and the E2 Cdc34. Rbx1 promotes association of Cdc34 with Cdc53 and stimulates Cdc34 auto-ubiquitination in the context of Cdc53 or SCF complexes. Rbx1, which is also a component of the von Hippel-Lindau tumor suppressor complex, may define a previously unrecognized class of E3-associated proteins.  (+info)

Recruitment of a ROC1-CUL1 ubiquitin ligase by Skp1 and HOS to catalyze the ubiquitination of I kappa B alpha. (5/749)

Activation of the transcription factor NF-kappa B in response to proinflammatory stimuli requires the phosphorylation-triggered and ubiquitin-dependent degradation of the NF-kappa B inhibitor, I kappa B alpha. Here, we show the in vitro reconstitution of the phosphorylation-dependent ubiquitination of I kappa B alpha with purified components. ROC1, a novel SCF-associated protein, is recruited by cullin 1 to form a quatemary SCFHOS-ROC1 holenzyme (with Skp1 and the beta-TRCP homolog HOS). SCFHOS-ROC1 binds IKK beta-phosphorylated I kappa B alpha and catalyzes its ubiquitination in the presence of ubiquitin, E1, and Cdc34. ROC1 plays a unique role in the ubiquitination reaction by heterodimerizing with cullin 1 to catalyze ubiquitin polymerization.  (+info)

ROC1, a homolog of APC11, represents a family of cullin partners with an associated ubiquitin ligase activity. (6/749)

We have identified two highly conserved RING finger proteins, ROC1 and ROC2, that are homologous to APC11, a subunit of the anaphase-promoting complex. ROC1 and ROC2 commonly interact with all cullins while APC11 specifically interacts with APC2, a cullin-related APC subunit. YeastROC1 encodes an essential gene whose reduced expression resulted in multiple, elongated buds and accumulation of Sic1p and Cln2p. ROC1 and APC11 immunocomplexes can catalyze isopeptide ligations to form polyubiquitin chains in an E1- and E2-dependent manner. ROC1 mutations completely abolished their ligase activity without noticeable changes in associated proteins. Ubiquitination of phosphorylated I kappa B alpha can be catalyzed by the ROC1 immunocomplex in vitro. Hence, combinations of ROC/APC11 and cullin proteins proteins potentially constitute a wide variety of ubiquitin ligases.  (+info)

Conjugation of the ubiquitin-like protein NEDD8 to cullin-2 is linked to von Hippel-Lindau tumor suppressor function. (7/749)

The von Hippel-Lindau tumor suppressor protein pVHL assembles with cullin-2 (hCUL-2) and elongin B/C forming a protein complex, CBCVHL, that resembles SKP1-CDC53-F-box protein ubiquitin ligases. Here, we show that hCUL-2 is modified by the conserved ubiquitin-like protein NEDD8 and that NEDD8-hCUL-2 conjugates are part of CBCVHL complexes in vivo. Remarkably, the formation of these conjugates is stimulated by the pVHL tumor suppressor. A tumorigenic pVHL variant, however, is essentially deficient in this activity. Thus, ligation of NEDD8 to hCUL-2 is linked to pVHL activity and may be important for pVHL tumor suppressor function.  (+info)

Cdc53/cullin and the essential Hrt1 RING-H2 subunit of SCF define a ubiquitin ligase module that activates the E2 enzyme Cdc34. (8/749)

SCFCdc4 (Skp1, Cdc53/cullin, F-box protein) defines a family of modular ubiquitin ligases (E3s) that regulate diverse processes including cell cycle, immune response, and development. Mass spectrometric analysis of proteins copurifying with Cdc53 identified the RING-H2 finger protein Hrt1 as a subunit of SCF. Hrt1 shows striking similarity to the Apc11 subunit of anaphase-promoting complex. Conditional inactivation of hrt1(ts) results in stabilization of the SCFCdc4 substrates Sic1 and Cln2 and cell cycle arrest at G1/S. Hrt1 assembles into recombinant SCF complexes and individually binds Cdc4, Cdc53 and Cdc34, but not Skp1. Hrt1 stimulates the E3 activity of recombinant SCF potently and enables the reconstitution of Cln2 ubiquitination by recombinant SCFGrr1. Surprisingly, SCF and the Cdc53/Hrt1 subcomplex activate autoubiquitination of Cdc34 E2 enzyme by a mechanism that does not appear to require a reactive thiol. The highly conserved human HRT1 complements the lethality of hrt1Delta, and human HRT2 binds CUL-1. We conclude that Cdc53/Hrt1 comprise a highly conserved module that serves as the functional core of a broad variety of heteromeric ubiquitin ligases.  (+info)
