Protein attributes

Sequence length	448 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Function	Catalytic component of the histone acetylase B (HAT-B) complex. Acetylates 'Lys-12' of histone H4 which is required for telomeric silencing. Has intrinsic substrate specificity that modifies lysine in recognition sequence GXGKXG. Involved in DNA double-strand break repair By similarity.
Catalytic activity	Acetyl-CoA + [histone] = CoA + acetyl-[histone].
Subunit structure	Component of the HAT-B complex composed of at least HAT1 and HAT2. The HAT-B complex binds to histone H4 tail By similarity.
Subcellular location	Cytoplasm By similarity. Nucleus By similarity.
Sequence similarities	Belongs to the HAT1 family.
