Ubiquitin-conjugating enzyme E2, catalytic (UBCc) domain/ubiquitin E2 variant (UEV) domain; ...
 2-86 4.77e-58

Ubiquitin-conjugating enzyme E2, catalytic (UBCc) domain/ubiquitin E2 variant (UEV) domain; The family includes ubiquitin-conjugating enzyme E2, catalytic (UBCc) domain and ubiquitin (Ub) E2 variant (UEV) domain. They belong to the ubiquitin-conjugating (UBC) superfamily that represents a structural domain with an alpha-beta(4)-alpha(3) core fold. E2 is part of the ubiquitin-mediated protein degradation pathway in which a thioester linkage forms between a conserved cysteine and the C-terminus of ubiquitin, and complexes with ubiquitin protein ligase enzymes, E3. This pathway regulates many fundamental cellular processes. There are also other E2s which form thioester linkages without the use of E3s. Several UBC homologs (TSG101, Mms2, Croc-1 and similar proteins) contains the UEV domain, which lacks the active site cysteine essential for ubiquitination and appear to function in DNA repair pathways.

 2-86 4.77e-58

ubiquitin E2 variant (UEV) domain of ubiquitin-conjugating enzyme E2 variant 1, 2 and related proteins; The E2V subfamily includes mammalian ubiquitin-conjugating enzyme E2 variant 1 (UBE2V1/CROC1/UBE2V/UEV1) and variant 2 (UBE2V2/MMS2/UEV2), yeast ubiquitin-conjugating enzyme variant MMS2, plant ubiquitin-conjugating enzyme E2 variant 1A (UEV1A/MMZ1) and variant 1B (UEV1B/MMZ2), and similar proteins. They have no ubiquitin ligase activity on their own. UBE2V1 (also called UEV-1, CROC-1, or TRAF6-regulated IKK activator 1 beta Uev1A) and UBE2V2 (also called DDVit 1, enterocyte differentiation-associated factor 1 (EDAF-1), enterocyte differentiation-promoting factor 1 (EDPF-1), MMS2 homolog, or vitamin D3-inducible protein) form heterodimers with UBE2N, respectively. Saccharomyces cerevisiae UEV MMS2 has a role in the DNA error-free postreplication repair (PRR) pathway. It forms a heterodimer with UBC13. Arabidopsis thaliana UEV1A and UEV1A form heterodimers with UBC35 or UBC36. The heterodimers possess ubiquitin-conjugating enzyme (EC 2.3.2.23) activity, catalyzing the synthesis of non-canonical poly-ubiquitin chains that are linked through 'Lys-63'. This type of poly-ubiquitination does not lead to protein degradation by the proteasome. Members of this subfamily may mediate transcriptional activation of target genes and plays a role in the control of progress through the cell cycle and differentiation. UEVs are homologous to E2 ubiquitin ligases but lack the conserved cysteine residue required for catalytic activity.

Ubiquitin-conjugating enzyme E2, catalytic (UBCc) domain of ubiquitin conjugating enzyme E2 T and related enzymes; The E2T subfamily includes mammalian ubiquitin-conjugating enzymes E2 T (UBE2T/HSPC150/PIG50), plant ubiquitin-conjugating enzyme E2 37 (UBC37), and similar proteins. They are ubiquitin-conjugating enzymes (EC 2.3.2.23) that accept ubiquitin from the E1 complex and catalyze the covalent attachment to other proteins. UBE2T, also called cell proliferation-inducing gene 50 protein, catalyzes monoubiquitination. It is involved in mitomycin-C (MMC)-induced DNA repair. It acts as a specific E2 ubiquitin-conjugating enzyme for the Fanconi anemia complex by associating with E3 ubiquitin-protein ligase FANCL and catalyzing monoubiquitination of FANCD2, a key step in the DNA damage pathway. UBE2T also mediates monoubiquitination of FANCL and FANCI. It may contribute to ubiquitination and degradation of BRCA1. In vitro, UBE2T can promote polyubiquitination using all 7 ubiquitin Lys residues, but may prefer 'Lys-11'-, 'Lys-27'-, 'Lys-48'- and 'Lys-63'-linked polyubiquitination.

 2-87 1.99e-06

Ubiquitin-conjugating enzyme E2, catalytic (UBCc) domain of ubiquitin-conjugating enzyme E2 K and related proteins; The E2J subfamily includes mammalian ubiquitin-conjugating enzymes E2 K (UBE2K/HIP2/LIG), yeast ubiquitin-conjugating enzyme E2 1 (UBC1), and plant ubiquitin-conjugating enzyme E2 27 (UBC27). They are ubiquitin-conjugating enzymes (EC 2.3.2.23) that accept ubiquitin from the E1 complex and catalyze the covalent attachment to other proteins. UBE2K is also called huntingtin-interacting protein 2 (HIP-2), ubiquitin-conjugating enzyme E2-25 kDa, or ubiquitin-conjugating enzyme E2(25K). In vitro, in the presence or absence of BRCA1-BARD1 E3 ubiquitin-protein ligase complex, UBE2K catalyzes the synthesis of 'Lys-48'-linked polyubiquitin chains. It does not transfer ubiquitin directly, but elongates monoubiquitinated substrate proteins. Saccharomyces cerevisiae UBC1, also called ubiquitin-conjugating enzyme E2-24 kDa, functions in the degradation of misfolded or regulated proteins localized in the endoplasmic reticulum (ER) lumen or membrane via the ubiquitin-proteasome system. It is a cognate E2 conjugating enzyme for the HRD1 ubiquitin ligase complex, which is part of the ERAD-L and ERAD-M pathways responsible for the rapid degradation of soluble lumenal and membrane proteins with misfolded lumenal domains (ERAD-L), or ER-membrane proteins with misfolded transmembrane domains (ERAD-M).

Ubiquitin-conjugating enzyme E2, catalytic (UBCc) domain of ubiquitin conjugating enzyme E2 S and related domains; The E2S subfamily includes mammalian ubiquitin-conjugating enzymes E2 S (UBE2S/E2EPF), plant ubiquitin-conjugating enzyme E2 22 (UBC22), and similar proteins. They are ubiquitin-conjugating enzymes (EC2.3.2.23) that accept ubiquitin from the E1 complex and catalyze the covalent attachment to other proteins. UBE2S catalyzes 'Lys-11'-linked polyubiquitination. It acts as an essential factor of the anaphase promoting complex/cyclosome (APC/C), a cell cycle-regulated ubiquitin ligase that controls progression through mitosis. UBE2S acts by specifically elongating 'Lys-11'-linked polyubiquitin chains initiated by the E2 enzyme UBE2C/UBCH10 on APC/C substrates, enhancing the degradation of APC/C substrates by the proteasome and promoting mitotic exit. It also acts by elongating ubiquitin chains initiated by the E2 enzyme UBE2D1/UBCH5 in vitro; it is however unclear whether UBE2D1/UBCH5 acts as an E2 enzyme for the APC/C in vivo. UBE2S is also involved in ubiquitination and subsequent degradation of VHL, resulting in an accumulation of HIF1A. In vitro, it can promote polyubiquitination using all 7 ubiquitin Lys residues, except 'Lys-48'-linked polyubiquitination.

It is a ubiquitin carrier protein required for the destruction of mitotic cyclins and proteins that maintain sister chromatid cohesion in animal cells and in Schizosaccharomyces pombe. In Saccharomyces cerevisiae, UBC11 is not essential for mitotic cyclin destruction. Arabidopsis thaliana UBC19 is part of the anaphase-promoting complex (APC). It may have a key function during cell cycle and be involved in cyclin B1 degradation.

ubiquitin E2 variant (UEV) domain of AKT-interacting protein and related proteins; AKTIP, also called Ft1, or fused toes protein homolog, is a component of the FTS/Hook/FHIP complex (FHF complex), which may function to promote vesicle trafficking and/or fusion via the homotypic vesicular protein sorting complex (the HOPS complex). AKTIP regulates apoptosis by enhancing phosphorylation and activation of AKT1. It increases release of TNFSF6 via the AKT1/GSK3B/NFATC1 signaling cascade. AKTIP contains a UEV domain that is homologous to E2 ubiquitin ligases but lacks the conserved cysteine residue required for catalytic activity.

Ubiquitin-conjugating enzyme E2, catalytic (UBCc) domain of ubiquitin-conjugating enzyme E2 N and related proteins; The E2N subfamily includes mammalian ubiquitin-conjugating enzymes E2 N (UBE2N/UBCH13/UBC13/BLU), yeast ubiquitin-conjugating enzyme E2 13 (UBC13), and plant ubiquitin-conjugating enzyme E2 35-36 (UBC35/UBC13A/UBG13A, UBC36/UBC13B/UBG13B), which function as ubiquitin-conjugating enzymes (EC 2.3.2.23). UBE2N, also called Bendless-like ubiquitin-conjugating enzyme, forms heterodimers with UBE2V1 and UBE2V2, respectively. The UBE2V1/UBE2N and UBE2V2/UBE2N heterodimers catalyze the synthesis of non-canonical 'Lys-63'-linked polyubiquitin chains. This type of polyubiquitination does not lead to protein degradation by the proteasome. UBE2N also plays a role in the control of progress through the cell cycle and differentiation, as well as in the error-free DNA repair pathway, and contributes to the survival of cells after DNA damage. Saccharomyces cerevisiae UBC13 has a role in the DNA error-free post-replication repair (PRR) pathway. The UBC13/MMS2 heterodimer catalyzes the synthesis of non-canonical poly-ubiquitin chains that are linked through 'Lys-63'. Arabidopsis thaliana UBC35 and UBC36 catalyze the synthesis of non-canonical poly-ubiquitin chains that are linked through 'Lys-63'. They mediate transcriptional activation of target genes. They are required for post-replication repair of UV-damaged DNA and for adapting root developmental programs to suboptimal availability of iron.
