Interactioni
Subunit structurei
Interacts with BCAS3.
Interacts with SIRT1.
Interacts with EP300, CREBBP and DDX17.
Component of a large chromatin remodeling complex, at least composed of MYSM1, KAT2B/PCAF, RBM10 and KIF11/TRIP5.
Interacts with KLF1; the interaction does not acetylate KLF1 and there is no enhancement of its transactivational activity.
Interacts with NFE4.
Interacts with MECOM.
Interacts with NR2C2 (hypophosphorylated and unsumoylated form); the interaction promotes the transactivation activity of NR2C2.
Interacts with NFE4.
Interacts with MECOM.
Interacts with E2F1; the interaction acetylates E2F1 augmenting its DNA-binding and transcriptional activity.
Interacts with NPAS2, ARNTL/BMAL1 and CLOCK (By similarity).
Interacts (unsumoylated form) with NR2C1; the interaction promotes transactivation activity.
Interacts with CEBPB (By similarity).
Interacts with NR4A3 (PubMed:12709428).
Interacts with TBX5 (By similarity).
Interacts with PLK4 (By similarity).
Interacts with RB1; this interaction leads to RB1 acetylation (PubMed:20940255).
