Anti-TSH3 antibodies enable researchers to detect and measure the TSH3 antigen in biological samples. This target is a reported synonym of the TSHZ3 gene, which encodes teashirt zinc finger homeobox 3. This protein is known to function in the regulation of transcription, among other biological roles. The human version of TSH3 has a canonical amino acid length of 1081 residues and a protein mass of 118.6 kilodaltons. It is reported to be localized in the nucleus of cells and widely expressed in many tissue types. TSH3 is a member of the Teashirt C2H2-type zinc-finger protein family.
