Coagulation
Coagulation — The process of blood clot formation involving a cascade of protease-mediated reactions, with several coagulation factors being peptide-based research targets.
What Is Coagulation?
Coagulation (blood clotting) is a proteolytic cascade in which inactive serine protease zymogens are sequentially activated, culminating in thrombin generation and fibrin clot formation. The coagulation cascade involves numerous peptide cleavage events, and several peptide anticoagulants (hirudin, bivalirudin) target cascade proteases directly.
Peptide Context
- Thrombin: Serine protease cleaving fibrinogen to fibrin. Target for hirudin-based anticoagulant peptides
- Thrombin receptor (PAR): Activated by thrombin cleavage exposing a tethered peptide agonist (SFLLRN)
- Sample collection: Anticoagulant choice affects peptide biomarker stability in blood samples
