Protein C, also known as autoprothrombin IIA and blood coagulation factor XIV, [5]: 6822 [6] is a zymogen, that is, an inactive enzyme.The activated form plays an important role in regulating anticoagulation, inflammation, and cell death and maintaining the permeability of blood vessel walls in humans and other animals.
Protein S (also known as PROS) is a vitamin K-dependent plasma glycoprotein synthesized in the liver. In the circulation, Protein S exists in two forms: a free form and a complex form bound to complement protein C4b-binding protein (C4BP). In humans, protein S is encoded by the PROS1 gene. [5] [6] Protein S plays a role in coagulation.
Protein C is vitamin K-dependent. Patients with Protein C deficiency are at an increased risk of developing skin necrosis while on warfarin. Protein C has a short half life (8 hour) compared with other vitamin K-dependent factors and therefore is rapidly depleted with warfarin initiation, resulting in a transient hypercoagulable state.
Protein S deficiency is a disorder associated with increased risk of venous thrombosis. [1] Protein S, a vitamin K-dependent physiological anticoagulant, acts as a nonenzymatic cofactor to activate protein C in the degradation of factor Va and factor VIIIa.
The presence of neurofibrillary tangles in the brain is one of the key hallmarks of Alzheimer’s disease. These irregular clumps of protein are closely associated with disease progression.
The body can make creatine on its own and from a diet that contains enough protein and creatine-rich food sources," she explains. "However, we know our bodies can only do so much, and there are ...

In warfarin's initial stages of action, inhibition of protein C and Factor VII is stronger than inhibition of the other vitamin K-dependent coagulation factors II, IX, and X. This results from the fact that these proteins have different half-lives : 1.5 to six hours for factor VII and eight hours for protein C, versus one day for factor IX, two ...
