Predicted to enable peptide alpha-N-acetyltransferase activity. Predicted to be involved in N-terminal peptidyl-methionine acetylation. Predicted to be located in cytosol and nucleus. Predicted to be part of NatB complex. Is expressed in several structures, including alimentary system; brain; heart; retina; and skin. Orthologous to human NAA20 (N-alpha-acetyltransferase 20, NatB catalytic subunit). [provided by Alliance of Genome Resources, Apr 2022]
