What pLDDT means and how to read it

Function

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)

Subunit structure

Component of the MOZ/MORF complex composed at least of ING5, KAT6A, KAT6B, MEAF6 and one of BRPF1, BRD1/BRPF2 and BRPF3 (PubMed:11965546). Interacts with RUNX1; phosphorylation of RUNX1 enhances the interaction (PubMed:11742995). Interacts with RUNX2 (PubMed:11965546). Interacts with p53/TP53 (PubMed:23431171). Interacts with PML (isoform PML-4) and this interaction positively regulates its…
