Protein Structure
UniProt Annotation
Function Deubiquitinates histone H2A, a specific tag for epigenetic transcriptional repression, thereby acting as a coactivator. Deubiquitination of histone H2A releaves the repression of di- and trimethylation of histone H3 at 'Lys-4', resulting in regulation of transcriptional initiation. Regulates gene expression via histone H2A deubiquitination. Also capable of removing NEDD8 from NEDD8 conjugates but has no effect on Sentrin- 1 conjugates. {ECO:0000269PubMed:18172164}.
Subcellular Localization Cytoplasm {ECO:0000250}. Nucleus {ECO:0000250}.
