UBCc_UEV super family cl49610
Ubiquitin-conjugating enzyme E2, catalytic (UBCc) domain/ubiquitin E2 variant (UEV) domain; ...
 94-124 5.48e-14

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.

 94-124 5.48e-14

Ubiquitin-conjugating enzyme E2, catalytic (UBCc) domain of ubiquitin-conjugating enzyme E2 C and related proteins; The E2C family includes mammalian ubiquitin-conjugating enzyme E2 C (UBE2C/UBCH10), yeast E2 ubiquitin-conjugating enzyme 11 (UBC11), plant ubiquitin-conjugating enzyme E2 19 (UBC19) and 20 (UBC20). 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. UBE2C, also known as (E3-independent) E2 ubiquitin-conjugating enzyme C (EC 2.3.2.24), E2 ubiquitin-conjugating enzyme C, ubiquitin carrier protein C, or ubiquitin-protein ligase C, catalyzes 'Lys-11'- and 'Lys-48'-linked polyubiquitination in vitro. 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.

 94-117 2.57e-03

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.
