General annotation (Comments)

Function	Acetyltransferase required for the establishment of sister chromatid cohesion and couple the processes of cohesion and DNA replication to ensure that only sister chromatids become paired together. In contrast to the structural cohesins, the deposition and establishment factors are required only during S phase. Ref.5 Ref.6
Subcellular location	Nucleus. Note: Nuclear at interphase, associated with chromosomes during mitosis. Ref.5 Ref.6
Tissue specificity	Widely expressed. Expressed in heart, brain, liver, placenta, lung, kidney and pancreas. Highly expressed in muscle. Ref.5
Domain	The N-terminal region seems to be responsible for the association with chromosomes, thus excluding any involvement of the Zn finger in this process.
Post-translational modification	Phosphorylated during mitosis. Phosphorylated upon DNA damage, probably by ATM or ATR. Ref.6 Ref.7 Ref.8
Sequence similarities	Belongs to the acetyltransferase family. GCN5 subfamily.
Caution	It is uncertain whether Met-1 or Met-2 is the initiator.
