Anti-PKD2L1 antibodies are used in the immunodetection of the protein polycystin 2 like 1, transient receptor potential cation channel. In humans, the canonical protein has a reported length of 805 amino acid residues and a mass of 92 kDa. Its subcellular localization is in the cell projections and cell membrane. Up to 5 different isoforms have been reported for this protein. It is notably expressed in taste bud cells in fungiform papillae. A member of the Polycystin protein family, PKD2L1 is reported to be a pore-forming subunit of a heterotetrameric, non-selective cation channel that is permeable to Ca(2+). Synonyms for this target antigen include PKD2L, PKDL, TRPP3, polycystic kidney disease 2-like 1 protein, polycystin-2 homolog, and PCL. PKD2L1 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of PKD2L1 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
