General description
The protein named Proteinase-activated receptor 1 (PAR-1/PAR1) or Coagulation factor II receptor, or Thrombin receptor and encoded by the human gene F2R/CR2R/PAR1/TR is a high affinity receptor for activated thrombin and part of the innate immune system response driven by proteinase-activated receptors (PARs). PARs are G protein-coupled receptors that transmit cellular responses to extracellular proteases and have important functions in vascular physiology, development, inflammation, and cancer progression. PAR1 is important for platelet activation and vascular development. PAR1 expression is limited to platelets and vascular endothelial cells and is localized to the cell membrane. Interestingly too, even the signal peptide of PAR1 (which guides the protein to the membrane) plays a role in cell signaling as if forms the intracellular angiogenesis inhibitor peptide Parstatin.
Immunogen
Linear peptide corresponding to human Par-1.

According to current models, human thrombin receptors are activated when thrombin cleaves the receptor's N terminus, exposing the tethered ligand domain, SFLLRN. In the megakaryoblastic CHRF-288 cell line, thrombin receptor activation is followed by the rapid internalization of > 90%

Based upon its recently cloned nucleotide sequence, the human platelet thrombin receptor is thought to be formed by a single polypeptide chain with seven transmembrane domains and an extracellular N terminus that can be cleaved by thrombin. As yet, however
