- SynonymFAP,FAPalpha,SIMP,Seprase,APCE
- SourceHuman FAP, Fc Tag (FAP-H5263) is expressed from human 293 cells (HEK293). It contains AA Leu 26 - Asp 760 (Accession # Q12884-1).Predicted N-terminus: ProRequest for sequence
- Molecular Characterization
This protein carries a human IgG1 Fc tag at the N-terminus.
The protein has a calculated MW of 111.5 kDa. The protein migrates as 110-125 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
- EndotoxinLess than 1.0 EU per μg by the LAL method.
- Purity
>90% as determined by SDS-PAGE.
- Formulation
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

Measured by its ability to convert the substrate benzyloxycarbonyl-Gly-Pro-7-amido-4-methylcoumarin (Z-GP-AMC) to Z-Gly-Pro and 7-amino-4-methylcoumarin (AMC).The specific activity is >4000 pmol/min/µg (QC tested).
2e5 of Anti-FAP CAR-293 cells were stained with 100 μL of 1 μg/mL of Human FAP Protein, Fc Tag (Cat. No. FAP-H5263) and negative control protein respectively, washed and then followed by PE anti-human IgG Fc antibody and analyzed with FACS (Routinely tested).
- BackgroundFAP (also known as seprase) is a Type II transmembrane serine protease. 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. Degrade also gelatin, heat-denatured type I collagen. Also has dipeptidyl peptidase activity, with a preference for Ala-Pro, Ile-Pro, Gly-Pro, Arg-Pro and Pro-Pro. 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. 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.
