**Background of Recombinant Human PROCA1 Protein**
Recombinant human PROCA1 (Protein C receptor variant 1), also known as endothelial protein C receptor (EPCR), is a membrane-associated glycoprotein involved in regulating coagulation, inflammation, and cellular signaling. Structurally, it belongs to the CD1/major histocompatibility complex family, characterized by a soluble extracellular domain that interacts with protein C, a key anticoagulant enzyme. PROCA1 enhances the activation of protein C by thrombin-thrombomodulin complexes, promoting anticoagulant pathways and cytoprotective effects.
Produced via recombinant DNA technology, PROCA1 is typically expressed in mammalian cell systems (e.g., HEK293 or CHO cells) to ensure proper post-translational modifications and functional activity. The recombinant protein is purified using affinity chromatography, retaining its ability to bind protein C and mediate signaling through protease-activated receptor 1 (PAR1).
Research highlights PROCA1's dual roles: in anticoagulation therapy for thrombosis-related disorders and in modulating inflammatory responses in sepsis or autoimmune diseases. Dysregulation of PROCA1 is linked to pathological conditions, including ischemic injury and chronic inflammation. Its recombinant form serves as a tool for studying protein C-mediated pathways and developing therapeutics targeting coagulation imbalances or endothelial dysfunction. Recent studies also explore its potential in organ protection and cancer biology, emphasizing its broad biomedical relevance.
