Anti-TRPP3 antibodies enable researchers to detect and measure the TRPP3 antigen in biological samples. This target is a reported synonym of the PKD2L1 gene, which encodes polycystin 2 like 1, transient receptor potential cation channel. This protein is known to function in the transport of ions and potassium ion transport, among other biological roles. The human version of TRPP3 has a canonical amino acid length of 805 residues and a protein mass of 92 kilodaltons, although 5 isoforms have been identified. It is reported to be localized in the cell projections and cell membrane of cells. Other names for this target antigen include PCL, PKD2L, and PKDL.
