General annotation (Comments)

Function	Catalyzes the covalent attachment of ubiquitin to other proteins. May be involved in degradation of katenin.
Catalytic activity	ATP + ubiquitin + protein lysine = AMP + diphosphate + protein N-ubiquityllysine.
Pathway	Protein modification; protein ubiquitination.
Subunit structure	Interacts with SCF (SKP1-CUL1-F-box protein) E3 ubiquitin ligase complex. When phosphorylated, interacts with beta-TrCP (BTRC).
Sequence similarities	Belongs to the ubiquitin-conjugating enzyme family.
