Function
YETS4_HUMAN Component of the NuA4 histone acetyltransferase (HAT) complex which is involved in transcriptional activation of select genes principally by acetylation of nucleosomal histones H4 and H2A. This modification may both alter nucleosome - DNA interactions and promote interaction of the modified histones with other proteins which positively regulate transcription. This complex may be required for the activation of transcriptional programs associated with oncogene and proto-oncogene mediated growth induction, tumor suppressor mediated growth arrest and replicative senescence, apoptosis, and DNA repair.

Publication Abstract from PubMed
Lysine succinylation is a newly discovered posttranslational modification with distinctive physical properties. However, to date rarely have studies reported effectors capable of interpreting this modification on histones. Following our previous study of SIRT5 as an eraser of succinyl-lysine (Ksuc), here we identified the GAS41 YEATS domain as a reader of Ksuc on histones. Biochemical studies showed that the GAS41 YEATS domain presents significant binding affinity toward H3K122suc upon a protonated histidine residue. Furthermore, cellular studies showed that GAS41 had prominent interaction with H3K122suc on histones and also demonstrated the coenrichment of GAS41 and H3K122suc on the p21 promoter. To investigate the binding mechanism, we solved the crystal structure of the YEATS domain of Yaf9, the GAS41 homolog, in complex with an H3K122suc peptide that demonstrated the presence of a salt bridge formed when a protonated histidine residue (His39) recognizes the carboxyl terminal of the succinyl group. We also solved the apo structure of GAS41 YEATS domain, in which the conserved His43 residue superimposes well with His39 in the Yaf9 structure. Our findings identified a reader of succinyl-lysine, and the binding mechanism will provide insight into the development of specific regulators targeting GAS41.
