  • FunctionSerine protease inhibitor. The major targets of this inhibitor are plasmin and trypsin, but it also inactivates matriptase-3/TMPRSS7 and chymotrypsin.
  • Tissue specificityExpressed by the liver and secreted in plasma.
  • Involvement in diseaseDefects in SERPINF2 are the cause of alpha-2-plasmin inhibitor deficiency (APLID) [MIM:262850]. APLID is an autosomal recessive disorder resulting in severe hemorrhagic diathesis.
  • Sequence similaritiesBelongs to the serpin family.
  • Cellular localizationSecreted.
  • Information by UniProt
