Anti-Cat Eye Syndrome Chromosome Region, Candidate 6 antibodies enable researchers to detect and measure the Cat Eye Syndrome Chromosome Region, Candidate 6 antigen in biological samples. This target is a reported synonym of the TMEM121B gene, which encodes transmembrane protein 121B. The human version of Cat Eye Syndrome Chromosome Region, Candidate 6 has a canonical amino acid length of 578 residues and a protein mass of 58.4 kilodaltons, although 2 isoforms have been identified. It is reported to be notably expressed in many tissues, such as the appendix, urinary bladder, and adrenal gland. Other names for this target antigen include CECR6, CECR6, and cat eye syndrome chromosome region, candidate 6.
