FunFam 122: Suppressor of tumorigenicity 14 protein homolog

There are 1 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Matriptase. [EC: 3.4.21.109]
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.
