General description

Fatty acid synthase (FAS, FASN) is encoded by the gene mapped to human chromosome 17q25.3.
Fatty acid synthase (FAS, FASN) is encoded by the gene mapped to human chromosome 17q25.3. In mammals, it is composed of two identical multifunctional polypeptides, in which three catalytic domains in the N-terminal section (β-ketoacyl synthase, malonyl/acetyl tansferase, and dehydrase) are separated by a core region of about 600 residues from four C-terminal domains (enoyl reductase, β-ketoacyl reductase, acyl carrier protein, and thioesterase).


synthetic peptide corresponding to amino acids 1982-1999 of mouse fatty acid synthase, conjugated to KLH via an N-terminal added cysteine residue. The immunizing peptide is conserved in rat and differs from the human sequence by three amino acids.


Anti-Fatty Acid Synthase antibody is suitable for western blot analysis at a concentration of 0.5-1μg/mL using lysates of mouse myoblast C2 cells and rat hepatocytoma FAO cells.
Fatty acid synthase antibody produced in rabbit has been used in immunohistochemistry and western blot analysis.

Biochem/physiol Actions

FAS plays an essential role during embryogenesis and energy homeostasis in adult animals. It also acts as the carbon source for fatty acid synthesis. It has been shown to be overexpressed in various types of human cancer, including prostate, breast, ovary and others. FASN is a multifunctional protein, mainly involved in catalyzing the synthesis of palmitate from acetyl-CoA and malonyl CoA, in the presence of NADPH.

Target description

Fatty Acid Synthase encodes an enzyme that is a multifunctional protein. Its main function is to catalyze the synthesis of palmitate from acetyl-CoA and malonyl-CoA, in the presence of NADPH, into long-chain saturated fatty acids.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.
