UBCc_UEV super family cl49610
Ubiquitin-conjugating enzyme E2, catalytic (UBCc) domain/ubiquitin E2 variant (UEV) domain; ...
 9-59 2.38e-37

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.

 9-59 2.38e-37

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.

 16-56 6.35e-04

Ubiquitin-conjugating enzyme E2, catalytic (UBCc) domain of Saccharomyces cerevisiae Peroxin-4 (PEX4) protein and related proteins; Saccharomyces cerevisiae PEX4 (EC 2.3.2.23), also called ubiquitin-conjugating enzyme E2-21 kDa, UBC10, or PAS2, acts as a ubiquitin-conjugating enzyme that catalyzes the covalent attachment of ubiquitin to other proteins. It is essential for peroxisome biogenesis and is required for UBC4-independent ubiquitination of PEX5. This subfamily also includes Arabidopsis thaliana PEX4 (also known as UBC21, EC 2.3.2.23) that is required for peroxisome biogenesis. It is necessary for the developmental elimination of obsolete peroxisome matrix proteins. It may be involved in the ubiquitination of PEX5, targeting it for recycling.

 17-56 8.60e-04

Ubiquitin-conjugating enzyme E2, catalytic (UBCc) domain of ubiquitin-conjugating enzyme E2 G1 and related proteins; The subfamily includes mammalian ubiquitin-conjugating enzymes E2 G1 (UBE2G1/UBC7/E217K), fission yeast ubiquitin-conjugating enzyme E2 15 (UBC15), plant ubiquitin-conjugating enzymes E2 7 (UBC7), E2 13 (UBC13) and E2 14 (UBC14). 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. In vitro, UBE2G1 catalyzes 'Lys-48'-, as well as 'Lys-63'-linked polyubiquitination. It may be involved in the degradation of muscle-specific proteins and may mediate polyubiquitination of CYP3A4. Schizosaccharomyces pombe UBC15 has a role in the formation of chromatin structures that influence the localization of transcriptional silencing factors. Arabidopsis thaliana UBC7, UBC13 and UBC14 are involved in the formation of multiubiquitin chains. They signal the protein for selective degradation.
