General annotation (Comments)

Function

Accepts ubiquitin from the E1 complex and catalyzes its covalent attachment to other proteins. In vitro catalyzes 'Lys-48'-linked polyubiquitination By similarity.

Catalytic activity

ATP + ubiquitin + protein lysine = AMP + diphosphate + protein N-ubiquityllysine.

Pathway

Protein modification; protein ubiquitination.

Subcellular location

Cytoplasm By similarity.

Tissue specificity

Detected at embryo implantation sites in the luminal epithelium of pregnant endometrium. Detected at low levels in ovary and liver. Ref.1

Induction

Up-regulated in pregnant endometrium during implantation.

Sequence similarities

Belongs to the ubiquitin-conjugating enzyme family.
