Related Product Information for PROC protein
Inactivation of Factor Va by Activated Protein C (APC): The inactivation of factor Va to form factor Vai results from proteolysis of the factor Va heavy chain (94K) at three specific sites by APC (1,2). The location of these cleavage sites in the factor Va heavy chain are as follows: (human: R306, R506, & R679) and (bovine: R306, R505, & R662). Complete inactivation of the cofactor molecule requires cleavage at the Arginine-306 position. Cleavage at Arginine-306 by activated protein C occurs only in the presence of membrane, and requires prior cleavage of the heavy chain at Arginine-505. Proteolysis of the factor Va light chain by APC occurs only in the bovine molecule and is not required for inactivation.

Activated protein C (APC) is an anticoagulant serine protease derived from the two chain, vitamin K-dependent zymogen, protein C (3-7). A complex between a-thrombin and thrombomodulin catalyzes a single cleavage at Arg-12 (Arg-14 in bovine) in the heavy chain of protein C, to generate APC. Several non-physiologically relevant proteases such as RVV-X activator, trypsin, and PROTAC are also capable of activating protein C.

NCBI Description

This gene encodes a vitamin K-dependent plasma glycoprotein. The encoded protein is cleaved to its activated form by the thrombin-thrombomodulin complex. This activated form contains a serine protease domain and functions in degradation of the activated forms of coagulation factors V and VIII. Mutations in this gene have been associated with thrombophilia due to protein C deficiency, neonatal purpura fulminans, and recurrent venous thrombosis.[provided by RefSeq, Dec 2009]

Uniprot Description

PROC: Protein C is a vitamin K-dependent serine protease that regulates blood coagulation by inactivating factors Va and VIIIa in the presence of calcium ions and phospholipids. Defects in PROC are the cause of thrombophilia due to protein C deficiency, autosomal dominant (THPH3). A hemostatic disorder characterized by impaired regulation of blood coagulation and a tendency to recurrent venous thrombosis. However, many adults with heterozygous disease may be asymptomatic. Individuals with decreased amounts of protein C are classically referred to as having type I protein C deficiency and those with normal amounts of a functionally defective protein as having type II deficiency. Defects in PROC are the cause of thrombophilia due to protein C deficiency, autosomal recessive (THPH4). A hemostatic disorder characterized by impaired regulation of blood coagulation and a tendency to recurrent venous thrombosis. It results in a thrombotic condition that can manifest as a severe neonatal disorder or as a milder disorder with late-onset thrombophilia. The severe form leads to neonatal death through massive neonatal venous thrombosis. Often associated with ecchymotic skin lesions which can turn necrotic called purpura fulminans, this disorder is very rare. Belongs to the peptidase S1 family.

Product Notes

The PROC proc (Catalog #AAA634328) is a Protein produced from Human plasma and is intended for research purposes only. The product is available for immediate purchase. It is sometimes possible for the material contained within the vial of "Protein C, Activated, Protein" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.
