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.
Application
Flow Cytometry Analysis: 4 µg from a representative lot detected Par-1 in 1X10E6 human thrombocytes (platelets).
Flow Cytometry Analysis: A representative lot from an independent laboratory detected Par-1 in CHRF-288 and HEL cells (Hoxie, J. A., et al. (1993). J Biol Chem. 268(18):13756-13763.).
Western Blotting Analysis: A representative lot from an independent laboratory detected Par-1 in human platelet membrane cell lysate (Brass, L. F., et al. (1992). J Biol Chem. 267(20):13795-13798.).
Immunocytochemistry Analysis: A representative lot from an independent laboratory detected Par-1 in CHRF-288 and HEL cells (Hoxie, J. A., et al. (1993). J Biol Chem. 268(18):13756-13763.).
Immunofluorescence Analysis: A representative lot from an independent laboratory detected Par-1 in CHRF-288 cells (Brass, L. F., et al. (1994). J Biol Chem. 269(4):2943-2952.).
This Anti-PAR-1 antibody, clone ATAP2 is validated for use in western blotting, flow cytometry, ICC & immunofluorescence for the detection of PAR-1.
