Predicted to enable histone H4 acetyltransferase activity and peptide alpha-N-acetyltransferase activity. Acts upstream of or within somitogenesis. Predicted to be located in cytosol and nucleus. Predicted to be part of NatA complex. Is expressed in blood vasculature; head; and myotome. Orthologous to human NAA50 (N-alpha-acetyltransferase 50, NatE catalytic subunit).
