The function of NAA60 (N-alpha-acetyltransferase 60, NatF catalytic subunit, Ensembl gene identifier ENSG00000122390) is as follows. N-alpha-acetyltransferase that specifically mediates the acetylation of N-terminal residues of the transmembrane proteins, with a strong preference for N-termini facing the cytosol (PubMed:25732826, PubMed:38480682). Displays N-terminal acetyltransferase activity towards a range of N-terminal sequences including those starting with Met-Lys, Met-Val, Met-Ala and Met-Met (PubMed:21750686, PubMed:25732826, PubMed:27320834, PubMed:27550639). Required for normal chromosomal segregation during anaphase (PubMed:21750686). May also show histone acetyltransferase activity; such results are however unclear in vivo and would require additional experimental evidences (PubMed:21981917). {ECO:0000269|PubMed:21750686, ECO:0000269|PubMed:25732826, ECO:0000269|PubMed:27320834, ECO:0000269|PubMed:27550639, ECO:0000269|PubMed:38480682, ECO:0000305|PubMed:21981917}.
