CC -!- FUNCTION: Histone deubiquitinating component of the transcription
CC regulatory histone acetylation (HAT) complex SAGA. Catalyzes the
CC deubiquitination of both histones H2A and H2B, thereby acting as a
CC coactivator. Recruited to specific gene promoters by activators, where
CC it is required for transcription (By similarity). {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Thiol-dependent hydrolysis of ester, thioester, amide, peptide
CC and isopeptide bonds formed by the C-terminal Gly of ubiquitin (a 76-
CC residue protein attached to proteins as an intracellular targeting
CC signal).; EC=3.4.19.12;
CC -!- SUBUNIT: Component of some SAGA transcription coactivator-HAT
CC complexes. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250|UniProtKB:Q5DU02}.
CC -!- SIMILARITY: Belongs to the peptidase C19 family. UBP8 subfamily.
CC {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AAH78033.1; Type=Erroneous initiation; Evidence={ECO:0000305};
