Anti-Cos17 antibodies enable researchers to detect and measure the Cos17 antigen in biological samples. This target is a reported synonym of the ZNF70 gene, which encodes zinc finger protein 70. This protein is suspected to be involved in transcriptional regulation. The human version of Cos17 has a canonical amino acid length of 446 residues and a protein mass of 50.8 kilodaltons. It is reported to be localized in the nucleus of cells. Cos17 is a member of the Krueppel C2H2-type zinc-finger protein family.
