General annotation (Comments)
| Function | Hydrolase that deubiquitinates target proteins such as the receptor ADORA2A, PDPK1 and TRIM21. Deubiquitination of ADORA2A increases the amount of functional receptor at the cell surface. Plays a role in the regulation of quality control in the ER By similarity. |
| Catalytic activity | 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). |
| Subunit structure | Interacts with RB1 (both dephosphorylated and hypophosphorylated forms). Interacts with ADORA2A (via cytoplasmic C-terminus); the interaction is direct. Interacts with RB1, RBL1 and RBL2 By similarity. |
| Subcellular location | Cytoplasm By similarity. Nucleus By similarity. Note: Shuttles between the nucleus and cytoplasm. Exported to the cytoplasm in a CRM1-dependent manner and recycled back to the nucleus via the importin alpha/beta heterodimeric import receptor. The relative amounts found in the nucleus and cytoplasm vary according to the cell type By similarity. |
| Domain | The Ubiquitin-like domain 2 inserts into the catalytic domain and competes with the ubiquitin substrate, partially inhibiting DUB activity By similarity. |
| Post-translational modification | Monoubiquitinated by TRIM21. Ubiquitination does not lead to its proteasomal degradation. Autodeubiquitinated By similarity. |
| Sequence similarities | Belongs to the peptidase C19 family. USP4 subfamily. Contains 1 DUSP domain. Contains 2 ubiquitin-like domains. |
