<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome.

Regulatory subunit of the histone acetylase B (HAT-B) complex. The complex acetylates 'Lys-12' of histone H4 which is required for telomeric silencing. HAT2 is required for high affinity binding of the acetyltransferase to histone H4, for the nuclear location of HAT1 and for the HAT1-HIF1 interaction. Alone, it is unable to bind to H4, requiring HAT1 for high affinity interaction with the histone tail. HAT2 has also a HAT1 independent function in life-span regulation.5 Publications
