CC -!- FUNCTION: N-alpha-acetyltransferase that acetylates the N-terminus of
CC proteins that retain their initiating methionine (By similarity). Has a
CC broad substrate specificity: able to acetylate the initiator methionine
CC of most peptides, except for those with a proline in second position
CC (By similarity). Also displays N-epsilon-acetyltransferase activity by
CC mediating acetylation of the side chain of specific lysines on proteins
CC (By similarity). Autoacetylates in vivo (By similarity). The relevance
CC of N-epsilon-acetyltransferase activity is however unclear: able to
CC acetylate H4 in vitro, but this result has not been confirmed in vivo
CC (By similarity). Component of N-alpha-acetyltransferase complexes
CC containing NAA10 and NAA15, which has N-alpha-acetyltransferase
CC activity (By similarity). Does not influence the acetyltransferase
CC activity of NAA10 (By similarity). However, it negatively regulates the
CC N-alpha-acetyltransferase activity of the N-terminal acetyltransferase
CC A complex (also called the NatA complex) (By similarity). The
CC multiprotein complexes probably constitute the major contributor for N-
CC terminal acetylation at the ribosome exit tunnel, with NAA10
CC acetylating all amino termini that are devoid of methionine and NAA50
CC acetylating other peptides (By similarity). Required for sister
CC chromatid cohesion during mitosis by promoting binding of CDCA5/sororin
CC to cohesin: may act by counteracting the function of NAA10 (By
CC similarity). {ECO:0000250|UniProtKB:Q9GZZ1}.
