Gcn5 acetylation
WebMar 21, 2024 · KAT2A, or GCN5, is a histone acetyltransferase (HAT) that functions primarily as a transcriptional activator. It also functions as a repressor of NF-kappa-B (see MIM 164011) by promoting ubiquitination of the NF-kappa-B subunit RELA (MIM 164014) in a HAT-independent manner (Mao et al., 2009 [PubMed 19339690]). [supplied by OMIM, … WebOct 16, 2009 · The finding that Gcn5 HAT activity is required for co-transcriptional recruitment of the U2 snRNP to DBP2 leads to the prediction that acetylation of DBP2 …

GCN5 is highly expressed in a variety of human cancers and promotes cancer progression by participating in the acetylation of many non-histone … WebNov 8, 2024 · work argues that nonhistone protein acetylation by Gcn5 is determined in part by specific amino acids surrounding target lysines but that even optimal sequences require both Ada2 and Ada3 for robust acetylation. the Ada2 SANT domain does not activate Gcn5's activity by directly affecting histone peptide binding as previously proposed.
WebHistone acetylation is an epigenetic modification that regulates numerous genes essential for various biological processes, including development and stress responses. ... Moreover, GCN5-mediated histone acetylation also plays an essential role in the phosphate starvation responses (PSR) through At4–miR399–PHO2 pathway .
WebNov 23, 2000 · Acetylation of all four H4 sites is unaffected by either hda1Δ or hda1Δgcn5Δ (data not shown). Therefore, GCN5 is responsible for histone H3 acetylation but not H4 acetylation over the... WebThe NuA4 KAT, Esa1, mediates increased H4 acetylation and enhanced RSC occupancy and histone eviction in coding sequences and stimulates the rate of transcription elongation. Esa1 cooperates with the H3 KAT in SAGA, Gcn5, to enhance these functions.
