Anti-trp-3 antibodies enable researchers to detect and measure the trp-3 antigen in biological samples. This target is a reported synonym of the TRPC3 gene, which encodes transient receptor potential cation channel subfamily C member 3. This protein is known to function in the transport of ions, among other biological roles. The human version of trp-3 has a canonical amino acid length of 921 residues and a protein mass of 105.5 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the cell membrane of cells. trp-3 is a member of the Transient receptor (TC 1.A.4) protein family.
