Anti-TAK-1 antibodies are protein reagents that detect specific antigens. The TAK-1 antigen is another term for the human protein nuclear receptor subfamily 2 group C member 2, encoded by the NR2C2 gene. The protein is known to function in cell differentiation and the regulation of transcription, among other biological roles. Canonically, it has an amino acid length of 596 residues and a mass of 65.4 kilodaltons. Its subcellular localization is in the nucleus and it is widely expressed in many tissue types. The TAK-1 protein is a member of the Nuclear hormone receptor protein family.
