Enables lysine N-acetyltransferase activity, acting on acetyl phosphate as donor. Acts upstream of or within several processes, including double-strand break repair; hematopoietic progenitor cell differentiation; and protein localization to chromatin. Located in chromocenter and chromosome. Is expressed in several structures, including alimentary system; brain; gonad; respiratory system; and sensory organ. Human ortholog(s) of this gene implicated in Roberts syndrome. Orthologous to human ESCO2 (establishment of sister chromatid cohesion N-acetyltransferase 2).
