Protocols

Specificity / Sensitivity

ATP-Citrate Lyase Antibody detects endogenous levels of total ATP-citrate lyase.

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues of human ATP-citrate lyase. Antibodies are purified by protein A and peptide affinity chromatography

Western Blotting

Western Blotting

Western blot analysis of extracts from HeLa, NIH/3T3, C6 and COS cells, using ATP-Citrate Lyase Antibody.

Background

ATP-citrate lyase (ACL) is a homotetramer that catalyzes the formation of acetyl-CoA and oxaloacetate (OAA) in the cytosol, which is the key step for the biosynthesis of fatty acids, cholestrol and acetylcholine, as well as for glucogenesis (1). Nutrients and hormones regulate the expression level and phosphorylation of ATP-citrate lyase (1,2). It is phosphorylated by GSK-3 on Thr446 and Ser450 (3). Ser455 of ATP-citrate lyase has been reported to be phosphorylated by PKA and Akt (4,5). Phosphorylation on Ser455 abolishes the homotropic allosteric regulation by citrate and enhances the catalytic activity of the enzyme (2).
