human ... FASN(2194)

General description

FASN (fatty acid synthase) is a large, multidomain, lipogenic protein. It is composed of seven catalytic domains, which include β-ketoacyl synthase (KS), malonyl acetyl transferase, dehydratase (DH), enoyl-acyl carrier protein-reductase (ER), β-ketoacyl reductase (KR), acyl carrier protein (ACP), and thioesterase domains. This protein exists in a functionally homodimeric form. Under normal conditions, it is expressed at low levels.

Application

All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project and as a result, are supported by the most extensive characterization in the industry.

The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. We also provide Prestige Antibodies® protocols and other useful information.

Biochem/physiol Actions

FASN (fatty acid synthase) is responsible for the biogenesis of long chain saturated fatty acids, which make up lipid signaling molecules, membranes and anchors for membrane proteins. This protein is linked to multiple disorders such as, hepatic steatosis, cancer, inflammation, obesity and diabetes. It is highly up-regulated in multiple cancers such as, breast, lung, prostate, colon, pancreatic and bladder. In breast cancer, this protein controls liver fatty acid-binding protein (L-FABP), vascular endothelial growth factor (VEGF) and VEGF Receptor-2 (VEGFR2), thus, promoting epithelial-mesenchymal transition of breast cancer cells. Trastuzumab-resistance in breast cancer is mediated by the up-regulation of FASN by Pin-1 (peptidylprolyl cis/trans isomerase, NIMA-interacting 1) protein. It is up-regulated in malignant gliomas, and might have potential as a therapeutic target for the drug Orlistat.

Features and Benefits

Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:
  • IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
  • Protein array of 364 human recombinant protein fragments.

Human fatty acid synthase (FAS) is a large, multidomain protein that synthesizes long chain fatty acids. Because these fatty acids are primarily provided by diet, FAS is normally expressed at low levels; however, it is highly up-regulated in many cancers.
