Structural highlights
FunctionKAT8_HUMAN Histone acetyltransferase which may be involved in transcriptional activation. May influence the function of ATM. As part of the MSL complex it is involved in acetylation of nucleosomal histone H4 producing specifically H4K16ac. As part of the NSL complex it may be involved in acetylation of nucleosomal histone H4 on several lysine residues. That activity is less specific than the one of the MSL complex.[1] [2] [3] Publication Abstract from PubMedA high-throughput screen for inhibitors of the histone acetyltransferase, KAT6A, led to identification of an aryl sulfonohydrazide derivative that inhibited KAT6A with an IC50 of 0.87M. Elaboration of the structure-activity relationship (SAR) and medicinal chemistry optimization led to discovery of WM-8014 (84), a highly potent inhibitor of KAT6A (IC50 = 0.008 M). WM-8014 competes with Ac-CoA and X-ray crystallographic analysis demonstrated binding to the Ac-CoA binding site. Through inhibition of KAT6A activity, WM-8014 induces cellular senescence and represents a unique pharmacological tool.
