Anti-OTK18 antibodies enable researchers to detect and measure the OTK18 antigen in biological samples. This target is a reported synonym of the ZNF175 gene, which encodes zinc finger protein 175. This protein is known to function in viral immune response and the regulation of transcription, among other biological roles. The human version of OTK18 has a canonical amino acid length of 711 residues and a protein mass of 81.6 kilodaltons. It is reported to be localized in the nucleus and cytoplasm of cells. OTK18 is a member of the Krueppel C2H2-type zinc-finger protein family.
