Genes affected

NAA15 (HGNC:30782): (N-alpha-acetyltransferase 15, NatA auxiliary subunit) N-alpha-acetylation is among the most common post-translational protein modifications in eukaryotic cells. This process involves the transfer of an acetyl group from acetyl-coenzyme A to the alpha-amino group on a nascent polypeptide and is essential for normal cell function. This gene encodes the auxillary subunit of the N-terminal acetyltransferase A (NatA) complex. [provided by RefSeq, Jan 2017]
