The function of KAT6A (lysine acetyltransferase 6A, Ensembl gene identifier ENSG00000083168) is as follows. Histone acetyltransferase that acetylates lysine residues in histone H3 and histone H4 (in vitro) (PubMed:11742995, PubMed:11965546). Component of the MOZ/MORF complex which has a histone H3 acetyltransferase activity (PubMed:11965546). May act as a transcriptional coactivator for RUNX1 and RUNX2 (PubMed:12771199). Acetylates p53/TP53 at 'Lys-120' and 'Lys-382' and controls its transcriptional activity via association with PML (PubMed:23431171). May play a role in leukemogenic gene transcription (PubMed:39794553). {ECO:0000269|PubMed:11742995, ECO:0000269|PubMed:11965546, ECO:0000269|PubMed:12771199, ECO:0000269|PubMed:16387653, ECO:0000269|PubMed:17925393, ECO:0000269|PubMed:23431171, ECO:0000269|PubMed:39794553}.
