Vitamin K-dependent protein Z

Gene

PROZ

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

Functioni

Appears to assist hemostasis by binding thrombin and promoting its association with phospholipid vesicles. Inhibits activity of the coagulation protease factor Xa in the presence of SERPINA10, calcium and phospholipids.

Caution

Although related to peptidase S1 family vitamin K-dependent clotting factors, it has lost two of the essential catalytic residues and therefore lacks protease activity.Curated
