histone acetyltransferase type B catalytic subunit (HAT1)

Function: - may play a role in telomeric silencing - acetylates soluble but not nucleosomal H4 at Lys-5 & Lys-12 - acetylates histone H2A at Lys-5 - HAT1 has intrinsic substrate specificity that modifies Lys in recognition sequence GXGKXG - heteromer of HAT1 & p46/HAT2 subunits acetyl-CoA + histone CoA + acetylhistone Structure: belongs to the HAT1 family Compartment: - nucleus; nuclear in S-phase - cytoplasm
