Recombinant Human lysine acetyltransferase 2A Protein, His tagged

• Cat.No.: KAT2A-080H
• Product Overview: Recombinant human KAT2A/GCN5 protein (Q92830) (Gly 497-Thr 662) with a His tag at the N-terminus and a His tag at the C-terminus was expressed in E. coli.

Specification

• Species: Human
• Source: E.coli
• Tag: His
• Protein Length: 497-662aa
• Description: Protein lysine acyltransferase that can act as a acetyltransferase, glutaryltransferase, succinyltransferase or malonyltransferase, depending on the context. Acts as a histone lysine succinyltransferase: catalyzes succinylation of histone H3 on 'Lys-79' (H3K79succ), with a maximum frequency around the transcription start sites of genes. Succinylation of histones gives a specific tag for epigenetic transcription activation. Association with the 2-oxoglutarate dehydrogenase complex, which provides succinyl-CoA, is required for histone succinylation. In different complexes, functions either as an acetyltransferase (HAT) or as a succinyltransferase: in the SAGA and ATAC complexes, acts as a histone acetyltransferase. Has significant histone acetyltransferase activity with core histones, but not with nucleosome core particles. Acetylation of histones gives a specific tag for epigenetic transcription activation. Recruited by the XPC complex at promoters, where it specifically mediates acetylation of histone variant H2A.Z.1/H2A.Z, thereby promoting expression of target genes.
