K(lysine) Acetyltransferase 2A (KAT2A) (Active) protein (His tag)
Description
GCN5 functions as a histone acetyltransferase (HAT) to promote transcriptional activation. Acetylation of histones gives a specific tag for epigenetic transcription activation. It has significant histone acetyltransferase activity with core histones, but not with nucleosome core particles. In case of HIV-1 infection, it is recruited by the viral protein Tat. It regulates Tat's transactivating activity and may help inducing chromatin remodeling of proviral genes. GCN5 is a component of the Ada Two-A containing (ATAC) complex, a complex with histone acetyltransferase activity on histones H3 and H4.
