These Paraneoplastic Antigen MA3 ELISA kits are immunodetection tools for measuring specific protein levels in biological samples. Paraneoplastic Antigen MA3 is an alias of the human PNMA3 gene, which encodes the protein, PNMA family member 3. Notably, Paraneoplastic Antigen MA3 is known to play a role in the regulation of apoptosis, among other functions. The PNMA3 protein is 463 amino acid residues in length and 52.4 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 notably expressed at high levels in the brain and testis. Other names for this target antigen include MA3, MA5, and paraneoplastic antigen Ma3.
