These CAA ELISA kits are immunodetection tools for measuring the levels of CAA in biological samples. CAA is an alias of the human TSHZ1 gene, which encodes the protein, teashirt zinc finger homeobox 1. Notably, CAA is known to play a role in the regulation of transcription, among other functions. The TSHZ1 protein is 1077 amino acid residues in length and 117.9 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. It is localized to the nucleus of the cell. In terms of tissue specificity, it is reported to be expressed in the brain; strongly reduced in post-mortem elderly subjects with Alzheimer disease. Other names for this target antigen include NY-CO-33. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
