Anti-PAR2 antibodies are used in antigen-specific immunodetection in biological samples. The target PAR2 is a known alias name of the protein F2R like trypsin receptor 1, encoded by the F2RL1 gene in humans. This 397-amino acid residue protein is a known receptor for trypsin and trypsin-like enzymes coupled to G proteins. It is localized to the cell membrane of the cell and features N-glycosylated, ubiquitinated, cleaved and phosphorylated post-translational modifications. In terms of tissue expression, it is found to be widely expressed in tissues with especially high levels in the pancreas, liver, kidney, small intestine, and colon.
