Protein
Ubiquitin carboxyl-terminal hydrolase 2
Gene
USP2, UBP41
Organism
Bos taurus (Bovine)
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. Deubiquitinates MDM2 without reversing MDM2-mediated p53/TP53 ubiquitination and thus indirectly promotes p53/TP53 degradation and limits p53 activity. Has no deubiquitinase activity against p53/TP53. Prevents MDM2-mediated degradation of MDM4. Plays a role in the G1/S cell-cycle progression in normal and cancer cells. Plays a role in the regulation of myogenic differentiation of embryonic muscle cells 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.

Enzyme regulationi

Cleavage is inhibited by ubiquitin in a dosage-dependent manner. Cleavage is blocked by ubiquitin aldehyde By similarity.

Interactioni

Subunit structurei

Homooligomer By similarity. Found in trimeric complex with MDM2 and MDM4 and UPB2. Interacts with CCND1; the interaction is direct and promotes its stabilization by antagonizing ubiquitin-dependent degradation. Interacts (via N-terminus and C-terminus) with MDM2. Interacts with MDM4 By similarity.
