Description

The FAP protein is a cell surface glycoprotein serine protease that is critical for extracellular matrix degradation and plays multiple roles in tissue remodeling, fibrosis, wound healing, inflammation, and tumor growth. FAP Protein, Human (Biotinylated, HEK293, His-Avi) is the recombinant human-derived FAP protein, expressed by HEK293 , with N-His, N-Avi labeled tag.

Background

FAP protein, a cell surface glycoprotein serine protease, plays a crucial role in extracellular matrix degradation and is involved in diverse cellular processes, including tissue remodeling, fibrosis, wound healing, inflammation, and tumor growth. Both the plasma membrane and soluble forms of FAP exhibit post-proline cleaving endopeptidase activity, demonstrating a preference for Ala/Ser-Gly-Pro-Ser/Asn/Ala consensus sequences on substrates such as alpha-2-antiplasmin SERPINF2 and SPRY2. FAP can degrade gelatin, heat-denatured type I collagen, and various other substrates. Additionally, it possesses dipeptidyl peptidase activity, hydrolyzing prolyl bonds in synthetic dipeptide substrates with a preference for specific amino acid sequences. In association with DPP4, PLAUR, or integrins, the plasma membrane form of FAP participates in pericellular proteolysis of the extracellular matrix, promoting cell adhesion, migration, and invasion. FAP's multifaceted functions extend to tissue remodeling during development and wound healing. In malignant melanoma cancers, FAP enhances cell invasiveness towards the extracellular matrix and promotes glioma cell invasion through the brain parenchyma by degrading the proteoglycan brevican. While contributing to tumor growth progression by increasing angiogenesis, collagen fiber degradation, and apoptosis, FAP paradoxically acts as a tumor suppressor in melanocytic cells through the regulation of cell proliferation and survival in a serine protease activity-independent manner.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

  • Specific Activity Calculator

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
× = ×

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
