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.

Fibroblast activation protein (FAP) is a cell-surface serine protease that acts on various hormones and extracellular matrix components. FAP is highly upregulated in a wide variety of cancers, and is often used as a marker for pro-tumorigenic stroma. It has

Dipeptidyl peptidase (DPP) 4 (CD26, DPP4) is a multi-functional protein involved in T cell activation by co-stimulation via its association with adenosine deaminase (ADA), caveolin-1, CARMA-1, CD45, mannose-6-phosphate/insulin growth factor-II receptor (M6P/IGFII-R) and C-X-C motif receptor 4 (CXC-R4). The proline-specific
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
