Ubiquitin-Conjugating Enzyme E2 G2/UBE2G2/UBC7 Protein(N-GST) (recombinant human)

Protein Construction: Recombinant Human Ubiquitin-Conjugating Enzyme E2 G2 is produced by our E.coli expression system and the target gene encoding Met1-Leu165 is expressed with a GST tag at the N-terminus. Sequence: Met 1-Leu165. Fusion tag: N-GST Endotoxin: < 1.0 EU per µg as determined by the LAL method. Apparent Molecular Mass: 43 kDa. Protein function: Ubiquitin-Conjugating Enzyme E2 G2 (UBE2G2) is an important cellular mechanism for targeting abnormal or short-lived proteins for degradation, which belong to the ubiquitin-conjugating enzyme family. It shares 60% and 100% sequence identity with S.cerevisiae Ubc7 and mouse respectively. The UBE2G2 enzyme and the GP78 E3 ligase are active components of endoplasmic reticulum-associated degradation pathway which is essential for the degradation of misfolded ER proteins. The mechanism of K48-linked poly-ubiquitination by UBE2G2/GP78 appears to involve the transfer of preassembled Ub chains from UBE2G2 to lysine residues in a substrate. The E2 and E3 enzymes form a large hetero-oligomer which brings multiple UBE2G2 molecules into close proximity which allows for Ub transfer between neighboring E2s. Protein function: Accepts ubiquitin from the E1 complex and catalyzes its covalent attachment to other proteins. In vitro catalyzes 'Lys- 48'-linked polyubiquitination. Involved in endoplasmic reticulum- associated degradation (ERAD). [The UniProt Consortium]
