FAP (also known as seprase) is a Type II transmembrane serine protease that is structurally related to dipeptidyl peptidase IV . FAP has substrate specificity similar to dipeptidyl peptidase IV, which is specific for N-terminal Xaa-Pro sequences, but FAP is also an endopeptidase able to degrade gelatin and Type I collagen. The enzymatically active form of FAP is a dimer . FAP has a restricted tissue distribution. It is not detectable in normal tissues or resting fibroblasts, but is highly expressed on reactive stromal fibroblasts in epithelial cancers , in granulation tissue during wound healing, and in bone and soft tissue sarcomas . Because of its expression patterns and enzymatic activities, FAP is believed to play roles in tumor invasion, tissue remodeling, and wound repair.
