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. Deubiquitinates BAZ2A\/TIP5 leading to its stabilization.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCellular localization:\u003c\/strong\u003e Nucleus.
