Fatty Acid Synthase (FAS) is a very large enzymatic system involved in de novo lipogenesis (triglyceride production). Specifically, FAS catalyzes the synthesis of palmitate from acetyl-CoA and malonyl-CoA, in the presence of NADPH, into long-chain saturated fatty acids. It is also one of the accepted markers for insulin resistance and SREBP, LXR activation.
In some cancer cell lines, FAS has been found to be fused with ER-alpha. Therefore, FAS antibodies are useful tools for studies on fatty acid synthesis and research on certian cancers.
