Protein

Protein Z-dependent protease inhibitor

Gene

SERPINA10

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Inhibits activity of the coagulation protease factor Xa in the presence of PROZ, calcium and phospholipids. Also inhibits factor XIa in the absence of cofactors.1 Publication

Miscellaneous

Heparin acts as an important cofactor, producing 20 to 100-fold accelerations of SERPINA10 reactions with factor Xa and factor XIa.
