Ubiquitin-conjugating enzyme E2, catalytic (UBCc) domain of ubiquitin conjugating enzyme E2 S ...
 13-158 1.40e-113

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.

 17-127 1.13e-42

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.

 19-158 6.53e-41

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.

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.

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).

 17-159 3.84e-24

Ubiquitin-conjugating enzyme E2, catalytic (UBCc) domain of ubiquitin-conjugating enzyme E2 L3, L5, L6 and related proteins; The E2L3-like subfamily includes mammalian ubiquitin-conjugating enzymes E2 L3 (UBE2L3/UBCH7/UBCE7), L5 (UBE2L5), L6 (UBE2L6/UBCH8), 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. UBE2L3 specifically acts with HECT-type and RBR family E3 ubiquitin-protein ligases. It does not function with most RING-containing E3 ubiquitin-protein ligases because it lacks intrinsic E3-independent reactivity with lysine: in contrast, it has activity with the RBR family E3 enzymes, such as PRKN and ARIH1, that function like RING-HECT hybrids. In vitro, UBE2L3 catalyzes 'Lys-11'-linked polyubiquitination. It is involved in the selective degradation of short-lived and abnormal proteins. In addition to ubiquitin, UBE2L6 also catalyzes the covalent attachment of ISG15 to other proteins. It functions in the E6/E6-AP-induced ubiquitination of p53/TP53. It promotes ubiquitination and subsequent proteasomal degradation of FLT3.

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. UBE2H (also E3-independent, EC 2.3.2.24) transfers ubiquitin to MAEA, a core component of the CTLH E3 ubiquitin-protein ligase complex. In vitro, UBE2H catalyzes 'Lys-11'- and 'Lys-48'-linked polyubiquitination. It might also ubiquitinate histone H2A. Saccharomyces cerevisiae UBC8 is required for the adaptation to the presence of glucose in the growth medium; it mediates the degradation of enzymes involved in gluconeogenesis when cells are shifted to glucose-containing medium. It is also required for proteasome-dependent catabolite degradation of fructose-1,6-bisphosphatase (FBP1).

ubiquitin-conjugating enzyme family protein; This subfamily includes ubiquitin-conjugating enzyme E2, catalytic (UBCc) domains mostly found in non-vertebrate eukaryotes. 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.

Ubiquitin-conjugating enzyme E2, catalytic (UBCc) domain of Saccharomyces cerevisiae CDC34 and related proteins; Saccharomyces cerevisiae CDC34 (EC 2.3.2.23), also called ubiquitin-conjugating enzyme E2-34 kDa, cell division control protein 34, E2 ubiquitin-conjugating enzyme 3 (UBC3), DNA6, or ubiquitin ligase complex SCF subunit CDC34, catalyzes the covalent attachment of ubiquitin to other proteins. In vitro, it may ubiquitinate histone H2A. CDC34 mediates the initiation of DNA replication (transition of G1 to S phase in cell cycle). It is the catalytic subunit of an SCF ubiquitin-protein ligase complex (together with Skp1p, Rbx1p, CDC53, and an F-box protein) that regulates cell cycle progression by targeting key substrates for degradation. Moreover, CDC34 is involved in the regulation of methionine biosynthesis genes and in the degradation of CDC6 together with CDC4 and CDC53.

Ubiquitin-conjugating enzyme E2, catalytic (UBCc)-like domain of baculoviral IAP repeat-containing protein 6 (BIRC6) and related proteins; BIRC6, also BIR repeat-containing ubiquitin-conjugating enzyme (BRUCE), RING-type E3 ubiquitin transferase (EC 2.3.2.27) BIRC6, or ubiquitin-conjugating BIR domain enzyme apollon (APOLLON), is an anti-apoptotic protein which can regulate cell death by controlling caspases and by acting as an E3 ubiquitin-protein ligase. It has an unusual ubiquitin conjugation system in that it could combine in a single polypeptide, ubiquitin conjugating (E2) with ubiquitin ligase (E3) activity, forming a chimeric E2/E3 ubiquitin ligase. Its targets include CASP9 and DIABLO/SMAC. BIRC6 acts as an inhibitor of CASP3, CASP7, and CASP9. BIRC6 is an important regulator for the final stages of cytokinesis. It is crucial for normal vesicle targeting to the site of abscission, but also for the integrity of the midbody and the midbody ring, and its striking ubiquitin modification.

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.

 37-120 1.16e-09

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.
