| Activity Regulation | ACTIVITY REGULATION: The completion of the deubiquitinase reaction is mediated by the DUSP and ubiquitin-like 1 domains which promotes the release of ubiquitin from the catalytic site enabling subsequent reactions to occur. {ECO:0000250|UniProtKB:Q13107}. |

| Calcium Binding | |
| catalytic Activity | CATALYTIC ACTIVITY: Reaction=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).; EC=3.4.19.12; Evidence={ECO:0000250|UniProtKB:Q13107}; |

| EC Number | 3.4.19.12 |
| Enzyme Function | FUNCTION: Deubiquitinating enzyme that removes conjugated ubiquitin from target proteins. Deubiquitinates PDPK1. Deubiquitinates TRIM21. Deubiquitinates receptor ADORA2A which increases the amount of functional receptor at the cell surface. May regulate mRNA splicing through deubiquitination of the U4 spliceosomal protein PRPF3. This may prevent its recognition by the U5 component PRPF8 thereby destabilizing interactions within the U4/U6.U5 snRNP. May also play a role in the regulation of quality control in the ER. {ECO:0000250|UniProtKB:Q13107}. |

| Subcellular Location | SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:P35123, ECO:0000250|UniProtKB:Q13107}. Nucleus {ECO:0000250|UniProtKB:P35123, ECO:0000250|UniProtKB:Q13107}. 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. {ECO:0000250|UniProtKB:P35123, ECO:0000250|UniProtKB:Q13107}. |

| Post Translational Modification | PTM: Monoubiquitinated by TRIM21. Ubiquitination does not lead to its proteasomal degradation. Autodeubiquitinated. {ECO:0000250|UniProtKB:Q13107}. |
