Product Usage Information Western Blotting: 1:1000 Storage Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/ml BSA and 50% glycerol. Store at -20°C. Do not aliquot the antibody. Protocol Available protocols: Western Blotting Specificity / Sensitivity HAT1 Antibody recognizes endogenous levels of total HAT1 protein. Species Reactivity: Human, Mouse, Rat, Monkey Source / Purification Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Val412 of human HAT1 protein. Antibodies are purified by peptide affinity chromatography. Background Histone acetyltransferase 1 (HAT1) is a member of the GCN5 family of acetyltransferases that can acetylate Lys5 and Lys12 on newly generated histone H4, a process that is essential for mammalian development (1-5). HAT1 binds to the H4 gene promoter, where it facilitates the production and acetylation of new histones. This process is strongly dependent on glucose availability, suggesting HAT1 plays a role in nutrient sensing (6). HAT1 has also been shown to contribute to recovery from replication-based DNA damage by incorporating H4Lys5/Lys12 acetylated histones at the sites of double-stranded breaks (7-9). HAT1 can acetylate non-histone proteins as well, and has been shown to play a key role in NF-kB signaling by acetylating PLZF, which in turn forms a complex with p50 to limit the production of cytokines (10). HAT1 overexpression has also been implicated in many cancer types (11-13).
