| Activity Regulation | ACTIVITY REGULATION: Cleavage is inhibited by ubiquitin in a dosage-dependent manner (By similarity). Cleavage is blocked by ubiquitin aldehyde. {ECO:0000250|UniProtKB:O75604, ECO:0000269|PubMed:10938131}. |

| 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; |

| Enzyme Function | FUNCTION: Hydrolase that deubiquitinates polyubiquitinated target proteins such as MDM2, MDM4 and CCND1 (By similarity). Isoform 1 and isoform 2 possess both ubiquitin-specific peptidase and isopeptidase activities (PubMed:12107281). Deubiquitinates MDM2 without reversing MDM2-mediated p53/TP53 ubiquitination and thus indirectly promotes p53/TP53 degradation and limits p53 activity (By similarity). Has no deubiquitinase activity against p53/TP53 (By similarity). Prevents MDM2-mediated degradation of MDM4 (By similarity). Plays a role in the G1/S cell-cycle progression in normal and cancer cells (By similarity). Regulates the circadian clock by modulating its intrinsic circadian rhythm and its capacity to respond to external cues (PubMed:23213472). Associates with clock proteins and deubiquitinates core clock component PER1 but does not affect its overall stability (PubMed:23213472). Regulates the nucleocytoplasmic shuttling and nuclear retention of PER1 and its repressive role on the clock transcription factors CLOCK and ARNTL/BMAL1 (By similarity). Plays a role in the regulation of myogenic differentiation of embryonic muscle cells (PubMed:12107281). {ECO:0000250|UniProtKB:O75604, ECO:0000250|UniProtKB:O88623, ECO:0000269|PubMed:10938131, ECO:0000269|PubMed:12107281, ECO:0000269|PubMed:23213472}.; FUNCTION: [Isoform 2]: Circadian clock output effector that regulates Ca(2+) absorption in the small intestine. Probably functions by regulating protein levels of the membrane scaffold protein NHERF4 in a rhythmic manner, and is therefore likely to control Ca(2+) membrane permeability mediated by the Ca(2+) channel TRPV6 in the intestine. {ECO:0000250|UniProtKB:O88623}. |

| Induction | INDUCTION: Up-regulated by IL-1. Isoform 1 is up-regulated with any signal for withdrawal from the cell cycle such as serum deprivation. {ECO:0000269|PubMed:12107281, ECO:0000269|PubMed:20403044}. |
