  • 功能：
    Cell surface glycoprotein serine protease that participates in extracellular matrix degradation and involved in many cellular processes including tissue remodeling, fibrosis, wound healing, inflammation and tumor growth. Both plasma membrane and soluble forms exhibit post-proline cleaving endopeptidase activity, with a marked preference for Ala/Ser-Gly-Pro-Ser/Asn/Ala consensus sequences, on substrate such as alpha-2-antiplasmin SERPINF2 and SPRY2. Degrade also gelatin, heat-denatured type I collagen, but not native collagen type I and IV, vitronectin, tenascin, laminin, fibronectin, fibrin or casein. Also has dipeptidyl peptidase activity, exhibiting the ability to hydrolyze the prolyl bond two residues from the N-terminus of synthetic dipeptide substrates provided that the penultimate residue is proline, with a preference for Ala-Pro, Ile-Pro, Gly-Pro, Arg-Pro and Pro-Pro. Natural neuropeptide hormones for dipeptidyl peptidase are the neuropeptide Y (NPY), peptide YY (PYY), substance P (TAC1) and brain natriuretic peptide 32 (NPPB). The plasma membrane form, in association with either DPP4, PLAUR or integrins, is involved in the pericellular proteolysis of the extracellular matrix (ECM), and hence promotes cell adhesion, migration and invasion through the ECM. Plays a role in tissue remodeling during development and wound healing. Participates in the cell invasiveness towards the ECM in malignant melanoma cancers. Enhances tumor growth progression by increasing angiogenesis, collagen fiber degradation and apoptosis and by reducing antitumor response of the immune system. Promotes glioma cell invasion through the brain parenchyma by degrading the proteoglycan brevican. Acts as a tumor suppressor in melanocytic cells through regulation of cell proliferation and survival in a serine protease activity-independent manner.

    1. FAP is virtually absent in normal tissues, but it is present in the embryonic and tumor tissues, which makes it a selective and versatile model. In this work, basic approaches to affecting the CAF using FAP as a target were discussed. PMID: 30383930
    2. In this study, s confirm that FAPalpha can promote the generation of Tregs and TAMs, which suggests that FAPalpha plays a immunosuppressive role in the tumor microenvironment PMID: 29273462
    3. Mounting evidence supported that miR-30a-5p directly targetted FAP and suppressed its expression in oral cavity cancer cells (OSCCs). By suppressing FAP expression, miR-30a-5p significantly inhibited cell propagation, migration, and invasion. Therefore, miR-30a-5p might be a new therapeutic target for oral cancer treatment. PMID: 29026005
    4. These results revealed that FAPalpha promoted the growth, adhesion and migration of lung squamous cell carcinoma cells. In addition, FAPalpha regulated lung cancer cell function, potentially via the PI3K and SHH pathways. Further investigations are required to examine the role of FAPalpha in lung AC cells. PMID: 29115573
    5. Several isoforms of DPP-IV and FAP are present in glioblastoma tissue. The absence of alkaline isoforms of both enzymes in glioma cell lines however suggests that isoforms from other, most likely stromal, cell types contribute to the overall pattern seen in glioblastoma tissues. PMID: 28452380
    6. These results indicated that the low plasma FAPalpha level might due to the systemic reaction to the presence of tumor and circulating FAPalpha level might be a potential indicator for diagnosing ESCC. PMID: 28415791

    9. Mutations to predicted TM interfacial residues (G10L, S14L, and A18L) comprising a small-X3-small motif reduced FAP TM-CYTO dimerization relative to wild type. Predicted off-interface residues showed no significant change from wild type. The interfacial TM residue G10L decreased FAP endopeptidase activity more than 25%, and reduced cell-surface versus intracellular expression relative to interfacial S14L and A18L. PMID: 27155568
