Anti-ataxia, cerebellar, Cayman type antibodies are protein reagents that detect specific antigens. The ataxia, cerebellar, Cayman type antigen is another term for the human protein ATCAY kinesin light chain interacting caytaxin, encoded by the ATCAY gene. The protein is reported to function in the development of neural tissues, particularly the postnatal maturation of the cerebellar cortex. Canonically, it has an amino acid length of 371 residues and a mass of 42.1 kilodaltons. Its subcellular localization is in the cell projections, mitochondria, and cytoplasm and it is expressed in the rectum, cerebral cortex, and cerebellum. Other alias names for ataxia, cerebellar, Cayman type include caytaxin, ATCAY, caytaxin, and BNIP-2-homolgy.
