Comment typeDescription
Catalytic ActivityATP + ubiquitin + protein lysine = AMP + diphosphate + protein N-ubiquityllysine. {ECO:0000255|PROSITE- ProRule:PRU00388, ECO:0000255|PROSITE-ProRule:PRU10133}.
FunctionRequired for peroxisome biogenesis. Necessary for the developmental elimination of obsolete peroxisome matrix proteins. May be involved in the ubiquitination of PEX5, targeting it for recycling. Accepts the ubiquitin from the E1 complex and catalyzes its covalent attachment to other proteins (By similarity). {ECO:0000250}.
PathwayProtein modification; protein ubiquitination. {ECO:0000255|PROSITE-ProRule:PRU00388}.
SimilarityBelongs to the ubiquitin-conjugating enzyme family. {ECO:0000255|PROSITE-ProRule:PRU00388}.
Subcellular LocationPeroxisome membrane {ECO:0000250}; Peripheral membrane protein {ECO:0000250}.
SubunitInteracts with PEX22. {ECO:0000269|PubMed:16272432}.
