Anti-Proteinase-Activated Receptor 4 antibodies enable researchers to detect and measure the Proteinase-Activated Receptor 4 antigen in biological samples. This target is a reported synonym of the F2RL3 gene, which encodes F2R like thrombin or trypsin receptor 3. This protein is known to function in signal transduction pathways, among other biological roles. The human version of Proteinase-Activated Receptor 4 has a canonical amino acid length of 385 residues and a protein mass of 41.1 kilodaltons. It is reported to be localized in the cell membrane of cells. Other names for this target antigen include PAR4 and F2R like thrombin/trypsin receptor 3. Western Blot is the most common application for the Proteinase-Activated Receptor 4 antibodies listed below. ELISA and Immunohistochemistry are also common applications.
