Ubiquitin specific peptidase 3
Ubiquitin specific processing protease 3
Ubiquitin Specific Protease 3
Ubiquitin thioesterase 3
Ubiquitin thiolesterase 3
Ubiquitin-specific-processing protease 3
FunctionHydrolase that deubiquitinates monoubiquitinated target proteins such as histone H2A and H2B. Required for proper progression through S phase and subsequent mitotic entry. May regulate the DNA damage response (DDR) checkpoint through deubiquitination of H2A at DNA damage sites. Associates with the chromatin.
Tissue specificityExpressed in all tissues examined, with strongest expression in pancreas.
Sequence similaritiesBelongs to the peptidase C19 family. USP3 subfamily. Contains 1 UBP-type zinc finger.
DomainBoth protease activity and an intact zinc finger are required for H2A monodeubiquitination.
Cellular localizationNucleus. Localizes preferentially with monoubiquitinated H2A to chromatin.
