Anti-Protor2 antibodies enable researchers to detect and measure the Protor2 antigen in biological samples. This target is a reported synonym of the PRR5L gene, which encodes proline rich 5 like. This protein is known to function in the response to oxidative stress and protein phosphorylation, among other biological roles. The human version of Protor2 has a canonical amino acid length of 368 residues and a protein mass of 40.8 kilodaltons, although 4 isoforms have been identified. Other names for this target antigen include proline-rich protein 5-like, Protein observed with Rictor-2, and protor-2.
