Protein

Ubiquitin carboxyl-terminal hydrolase 2

Gene

USP2

Organism
Gallus gallus (Chicken)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at transcript leveli

Functioni

Hydrolase that deubiquitinates polyubiquitinated target proteins such as MDM2, MDM4 and CCND1. Possesses both ubiquitin-specific peptidase and isopeptidase activities By similarity.By similarity

Catalytic activityi

Thiol-dependent hydrolysis of ester, thioester, amide, peptide and isopeptide bonds formed by the C-terminal Gly of ubiquitin (a 76-residue protein attached to proteins as an intracellular targeting signal).

Cofactori

Binds 1 zinc ion.By similarity
