Plasmin/Antiplasmin Complex (PAP) Antibody – Mouse Monoclonal

This gene encodes a member of the serpin family of serine protease inhibitors. The protein is a major inhibitor of plasmin, which degrades fibrin and various other proteins. Consequently, the proper function of this gene has a major role in regulating the blood clotting pathway. Mutations in this gene result in alpha-2-plasmin inhibitor deficiency, which is characterized by severe hemorrhagic diathesis. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2009]

SERPINF2: Serine protease inhibitor. The major targets of this inhibitor are plasmin and trypsin, but it also inactivates matriptase-3/TMPRSS7 and chymotrypsin. Defects in SERPINF2 are the cause of alpha-2-plasmin inhibitor deficiency (APLID). APLID is an autosomal recessive disorder resulting in severe hemorrhagic diathesis. Belongs to the serpin family. 2 isoforms of the human protein are produced by alternative splicing.
