HBO1, HBOa, KAT7, MOZ, MYST 2, MYST protein 2, MYST2, SAS 2, SAS2 and TIP60 protein 2, TIP60 protein 2, YBF2/SAS3, ZC2HC7.
Catalytic subunit of histone acetyltransferase HBO1 complexes, which specifically mediate acetylation of histone H3 at Lys-14 (H3K14ac), thereby regulating various processes, such as gene transcription, protein ubiquitination, immune regulation, stem cell pluripotent and self-renewal maintenance and embryonic development.
