Protein attributes

Sequence length	318 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Catalyzes the covalent attachment of ubiquitin to other proteins. Seems to function in the selective degradation of misfolded membrane proteins from the endoplasmic reticulum. Ref.2
Catalytic activity	ATP + ubiquitin + protein lysine = AMP + diphosphate + protein N-ubiquityllysine.
Pathway	Protein modification; protein ubiquitination.
Subcellular location	Endoplasmic reticulum membrane; Single-pass type IV membrane protein Ref.2.
Sequence similarities	Belongs to the ubiquitin-conjugating enzyme family.
Sequence caution	The sequence AAF36125.1 differs from that shown. Reason: Frameshift at position 119.
