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.

Contains 1 N-acetyltransferase domain.
