5 µg of Recombinant KAT2A (GCN5) protein, active. KAT2A (GCN5) is formulated in 20 mM Tris-HCl pH 7.3, 20% glycerol, 0.2 mM EDTA, 300 mM KCl, 1 mM DTT containing 0.5 mM PMSF. Please refer to product insert upon arrival for lot-specific concentration.

for Recombinant KAT2A (GCN5) proteinBackground

GCN5 (General control of nutrition 5), also known as K (lysine) acetyltransferase 2A (KAT2A), is a component of the ATAC complex, which is a complex that specifically exerts histone acetyltransferase (HAT) activity on histones H3 and H4. KAT2A (GCN5) acts as a histone acetyltransferase to promote transcriptional activation. In the case of HIV-1 infection, it is recruited by the viral protein TAT and regulates TAT's transactivating activity. In addition, evidence suggests KAT2A (GCN5) may play a role in the induction of chromatin remodeling of proviral genes. KAT2A (GCN5) also functions as a repressor of NFκB by promoting ubiquitination of the NFκB subunit RelA in a HAT-independent manner.

for Recombinant KAT2A (GCN5) proteinApplication Notes

This protein has been tested for activity in the fluorescent HAT Assay Kit, Catalog No. 56100. 50 ng of KAT2A (GCN5) were assayed per well using 50 µM histone H3 peptide substrate, 50 µM Acetyl-CoA and incubated for 30 minutes at room temperature. The assay was read on a fluorescent plate reader (ex. 360-390 nm, em. 450-470 nm). The specific activity was 100 pmol/min/µg.

Recombinant KAT2A (GCN5) protein activity assay

Recombinant GCN5 protein activity assay.
GCN5 activity assayed with the fluorescent HAT assay (Catalog No. 56100) using 50 ng of GCN5, 50 µM histone H3 peptide substrate (residues 5-23 of human H3), 50 µM Acetyl-CoA and 15 µM Anacardic Acid for inhibition. GCN5 was assayed alone to determine background and the resulting value was subtracted from this data.
