      Background InformationProteinase-activated receptor 4 (UniProt Q96RI0; also known as Coagulation factor II receptor-like 3, PAR-4, Thrombin receptor-like 3) is encoded by the F2RL3 (also known as PAR4) gene (Gene ID 9002) in human. Protease-activated receptors (PARs) constitute a unique family of seven-transmembrane, G-protein-coupled receptors (GPCRs) activated by proteolytic cleavage of their N-terminal propeptide sequence. Once cleaved off, the N-terminal propeptide fragment functions as a ligand and activates the receptor by binding the second extracellular loop. The four PAR family members (PAR-1 to PAR-4) are widely expressed and activated by multiple proteases, and utilize different types of G-proteins (Gi, Gq, and G12/13) for signal transdution depending on the activating protease and cellular context. PAR-4 is expressed on platelets and exhibits a low-affinity for thrombin. However, PAR-4 is able to form hetero-oligomers with both PAR-1 and the ADP receptor P2Y12 to mediate thrombin- and ADP-initiated signaling. PAR-4 cleavage is significantly enhanced through hetero-oligomerization with PAR-1, and PAR-4 interaction with P2Y12 is directly linked to arrestin-2 recruitment and AKT signaling. PAR-4 is a 7-transmembrane (a.a. 83-103, 109-129, 152-172, 192-213, 248-268, 284-304, 320-343) GPCR activated by thrombin cleavage between R47 and G48, having 3 extracellular loops and 3 intracellular loops between the extracellular N-terminal end (a.a. 48-82) the cytoplasmic C-terminal tail (a.a. 344-385).

      Applications
      ApplicationAnti-PAR4 Antibody, clone 5F10 is an antibody against PAR4 for use in Western Blotting, Immunocytochemistry, Flow Cytometry, Inhibition.
      Key Applications
      • Western Blotting
      • Immunocytochemistry
      • Flow Cytometry
      • Inhibition
      Application NotesImmunocytochemistry Analysis: 20 µg/mL from a representative lot detected endogenous PAR4 by fluorescent immunocytochemistry staining of freshly isolated human platelets (Courtesy of Dr. Marvin Nieman, Case Western Reserve University, Cleveland, OH, USA).
      Immunocytochemistry Analysis: A representative lot detected the expression of exogenously transfected human PAR4 by fluorescent immunocytochemistry staining of 4% formaldehyde-fixed HEK293 Flp-In cells following tetracycline treatment (Mumaw, M.M., et al. (2015). Thromb. Res. 135(6):1165-1171).
      Flow Cytometry Analysis: A representative lot detected tetracycline-induced expression of exogenously transfected human PAR4 on the surface of HEK293 Flp-In cells. Thrombin treatment diminished cell surface PAR4 immunoreactivity (Mumaw, M.M., et al. (2015). Thromb. Res. 135(6):1165-1171).
      Inhibition Analysis: A representative lot, when added prior to thrombin, protected cell surface PAR4 against thrombin cleavage (Mumaw, M.M., et al. (2015). Thromb. Res. 135(6):1165-1171).
      Western Blotting Analysis: A representative lot detected MBP fusion proteins containing human PAR4 fragment a.a. 18-78 or 41-66, but not 48-72. MBP-PAR4 fusion degradation by thrombin treatment ablolished target band detection by clone 5F10 (Mumaw, M.M., et al. (2015). Thromb. Res. 135(6):1165-1171).
      Western Blotting Analysis: A representative lot detected tetracycline-induced expression of exogenously introduced human PAR4 in a HEK293 Flp-In cell line, as well as endogenous PAR4 in isolated human platelets (hPLTs). Thrombin activation of hPLTs diminished PAR4 target band detection (Mumaw, M.M., et al. (2015). Thromb. Res. 135(6):1165-1171).

      SpecificityClone 5F10 recognizes a propeptide epitope near (N-terminal to) the thrombin-cleavage site and protects cell surface PAR4 against thrombin cleavage (Mumaw, M.M., et al. (2015). Thromb. Res. 135(6):1165-1171). Clone 5F10 recognizes prepro- and pro-, but not proteolytically activated, forms of human PAR4.
