Measured by its ability to cleave the fluorogenic peptide substrate, Mca-RPKPVE-Nval-WRK(Dnp)-NH2. The specific activity is >15 pmol/min/µg, as measured under the described conditions.
Purity ≥95% (SDS-PAGE) Endotoxin level ＜0.1 EU/μg Function Hepatocyte Growth Factor Activator (HGFA) is a serine endopeptidase that cleaves at the peptide bond between Arg494 and Val495 of single-chain human HGF precursor, generating the active heterodimer. HGFA is produced and secreted by the liver and normally circulates in the blood as an inactive zymogen. The zymogen has a weak affinity for heparin but acquires a strong affinity for heparin upon activation that is linked to blood coagulation. This property may ensure the local action of this enzyme at the site of tissue injury . Human HGFA precursor (655 amino acid residues) contains several predicted domains including a signal peptide (residues 1‑30), a propeptide (residues 31-372), and a mature and active form (residues 373-655) that is further processed into a short chain (residues 373‑407) and a long chain (residues 408-655). The short chain and the long chain (catalytic domain) may form a disulfide bond linked dimer. HGFA can be activated by thrombin or thermolysin . The active protease can be inhibited by HGFA inhibitors (HAIs). Two HAIs, HAI-1 and HAI-2, are known in mouse and human. HAI-1 is not only an inhibitor, but also a specific acceptor of active HGFA, acting as a reservoir of this enzyme on the cell surface.

Recombinant Human HGF Activator Protein (rp166574) - SDS-PAGE 3 μg/lane of Recombinant Human HGF Activator Protein consists of 630 amino acids and has a predicted molecular mass of 68 kDa. As a result of proteolysis or autocatalysis and glycosylation, it migrates as three bands (37, 60, 105 kDa) in SDS-PAGE under reducing conditions, corresponding to the active long chain, uncleaved single chain (long chain + short chain), pro domain and the full-length pro form of HGFA respectively.
