Anti-TDRD4 antibodies enable researchers to detect and measure the TDRD4 antigen in biological samples. This target is a reported synonym of the RNF17 gene, which encodes ring finger protein 17. This protein is known to function in spermatid development, among other biological roles. The human version of TDRD4 has a canonical amino acid length of 1623 residues and a protein mass of 184.6 kilodaltons, although 5 isoforms have been identified. It is reported to be localized in the nucleus and cytoplasm of cells and widely expressed in many tissue types.
