Gene Information

human ... FAP(2191)

General description

FAP gene is localized on human chromosome 2q24.2.
Fibroblast activation protein (FAP) is a type II transmembrane serine protease and a cell surface antigen. It is present as a homodimeric integral protein with dipeptidyl peptidase IV like fold. FAP has an α/β-hydrolase domain and an eight-bladed β-propeller domain. It is not expressed in normal tissues. The protein is only expressed by activated fibroblasts in response to pathologic situations.

Immunogen

Synthetic 18 amino acid peptide from extracellular domain of human FAP. Percent identity with other species by BLAST analysis: Human, Gorilla, Gibbon (100%); Monkey (94%); Bovine (89%); Marmoset (83%).

Application

Anti-FAP (AB1) antibody produced in rabbit has been used in immunohistochemistry.

Biochem/physiol Actions

Fibroblast activation protein (FAP) is expressed in several pathogenic sites including cancer, fibrosis, arthritis, wounding, or inflammation. FAP has in vitro dipeptidyl peptidase activity and collagenolytic activity. It cleaves N-terminal dipeptides from polypeptides and can degrade gelatin and type I collagen.

Cancer-associated fibroblasts (CAF) are components of the tumor microenvironment whose contributions to malignant progression are not fully understood. Here, we show that the fibroblast activation protein (FAP) triggers induction of a CAF subset with an inflammatory phenotype directed by STAT3
