Anti-P53AIP1 antibodies enable researchers to detect and measure the P53AIP1 antigen in biological samples. This target is a reported synonym of the TP53AIP1 gene, which encodes tumor protein p53 regulated apoptosis inducing protein 1. This protein is known to function in the apoptotic pathway, among other biological roles. The human version of P53AIP1 has a canonical amino acid length of 124 residues and a protein mass of 12.9 kilodaltons, although 4 isoforms have been identified. It is reported to be localized in the mitochondria of cells.
