Anti-PRR2 antibodies are protein reagents that detect specific antigens. The PRR2 antigen is another term for the human protein nectin cell adhesion molecule 2, encoded by the NECTIN2 gene. The protein is known to function in cytoskeleton organization and cellular localization, among other biological roles. Canonically, it has an amino acid length of 538 residues and a mass of 57.7 kilodaltons. Its subcellular localization is in the cell membrane and it is ubiquitously expressed across many tissue types. The PRR2 protein is a member of the Nectin protein family.
