Anti-NY-REN-45 antibodies enable researchers to detect and measure the NY-REN-45 antigen in biological samples. This target is a reported synonym of the KCTD3 gene, which encodes potassium channel tetramerization domain containing 3. This protein is known to function in protein oligomerization, among other biological roles. The human version of NY-REN-45 has a canonical amino acid length of 815 residues and a protein mass of 89 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the cell membrane of cells and widely expressed in many tissue types. This target antigen may also be known as BTB/POZ domain-containing protein KCTD3.
