Structure of human ubiquitin-conjugating enzyme E2 G2 (UBE2G2/UBC7)
Structural highlights
FunctionUB2G2_HUMAN 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).[1] [2] Evolutionary Conservation Check, as determined by ConSurfDB.

Publication Abstract from PubMedThe human ubiquitin-conjugating enzyme E2 G2 (UBE2G2/UBC7) is involved in protein degradation, including a process known as endoplasmic reticulum-associated degradation (ERAD). The crystal structure of human UBE2G2/UBC7 was solved at 2.56 angstroms resolution. The UBE2G2 structure comprises a single domain consisting of an antiparallel beta-sheet with four strands, five alpha-helices and two 3(10)-helices. Structural comparison of human UBE2G2 with yeast Ubc7 indicated that the overall structures are similar except for the long loop region and the C-terminal helix. Superimposition of UBE2G2 on UbcH7 in a c-Cbl-UbcH7-ZAP70 ternary complex suggested that the two loop regions of UBE2G2 interact with the RING domain in a similar way to UbcH7. In addition, the extra loop region of UBE2G2 may interact with the RING domain or its neighbouring region and may be involved in the binding specificity and stability.
