General description
Fibroblast activation protein alpha (FAPa) is a type II transmembrane serine protease. It is present as a homodimeric integral protein with dipeptidyl peptidase IV like fold. It has an α/β-hydrolase domain and an eight-bladed β-propeller domain. It is not expressed in normal tissue. It is only expressed by activated fibroblast in response to pathologic situations. It is expressed in several pathogenic sites including cancer, fibrosis, arthritis, wounding, or inflammation.
Application
FAPa may be used to study the role in coordinating the stromal response to cancer, in angiogenesis, and modulation of the antitumor immune response.
Biochem/physiol Actions
FAPα has in vitro dipeptidyl peptidase activity and collagenolytic activity. It cleaves N-terminal dipeptides from polypeptides and can degrade gelatin and type I collagen. It has also been reported that FAPa has a tumor suppressor activity.
FAP is a Type II transmembrane serine protease which has substrate specificity for prolyl peptides bonds (Pro-Xaa). This endopeptidase cleaves gelatin and is believed to play a role in tissue remodeling, tumor invasion, and wound repair.

Fibroblast activation protein-α (FAP) is a serine protease that can provide target specificity to therapeutic agents because in adults its expression is restricted to pathologic sites, including cancer, fibrosis, arthritis, wounding, or inflammation. It is not expressed in most normal

Fibroblast activation protein (FAP), a selective protein for tumor stromal fibroblasts, is expressed in >90% of human epithelial carcinomas. A characteristic feature of pancreatic cancer is an extensive fibrotic or desmoplastic reaction surrounding the primary tumor. The present study aimed
