CC -!- FUNCTION: N-alpha-acetyltransferase that acetylates the N-terminus of
CC proteins that retain their initiating methionine. Has a broad substrate
CC specificity: able to acetylate the initiator methionine of most
CC peptides, except for those with a proline in second position. Also
CC displays N-epsilon-acetyltransferase activity by mediating acetylation
CC of the side chain of specific lysines on proteins. The relevance of N-
CC epsilon-acetyltransferase activity is however unclear. Required for
CC sister chromatid cohesion during mitosis by promoting binding of
CC CDCA5/sororin to cohesin. {ECO:0000250|UniProtKB:Q9GZZ1}.
