Enzyme Information

3.4.21.109

Matriptase.

based on mapping to UniProt Q9Y5Y6

Cleaves various synthetic substrates with Arg or Lys at the P1 position and prefers small side-chain amino acids, such as Ala and Gly, at the P2 position.

-!- This trypsin-like integral-membrane serine peptidase has been implicated in breast cancer invasion and metastasis. -!- Can activate hepatocyte growth factor/scattering factor (HGF/SF) by cleavage of the two-chain form at an Arg residue to give active alpha- and beta-HGF, but it does not activate plasminogen, which shares high homology with HGF. -!- Can also activate urokinase plasminogen activator (uPA), which initiates the matrix-degrading peptidase cascade. -!- Belongs to peptidase family S1A.
