These B55BETA ELISA kits are immunodetection tools for measuring the levels of B55BETA in biological samples. B55BETA is an alias of the human PPP2R2B gene, which encodes the protein, protein phosphatase 2 regulatory subunit Bbeta. Notably, B55BETA is known to play a role in the apoptotic pathway, among other functions. The PPP2R2B protein is 443 amino acid residues in length and 51.7 kilodaltons in mass. However, as many as 7 protein isoforms have been identified. It is localized to the mitochondria and cytoplasm of the cell. In terms of tissue specificity, it is notably expressed in the brain.
