Listed are ELISA Kits for the detection of (P)RR, an alias name of ATPase H+ transporting accessory protein 2. The human protein, encoded by the gene ATP6AP2, is 350 amino acid residues long and has a mass of 39,008 daltons. However, there are up to 2 reported isoforms. This protein is reported to have a membrane cellular localization. The gene is associated with Mental retardation, X-linked, with epilepsy. For this target protein, ELISA kits with the following species reactivities are available: human, mouse, rat, and bovine. This target may also be known as: ATPase H(+)-transporting lysosomal-interacting protein 2, ATPase H+ transporting lysosomal accessory protein 2, ER-localized type I transmembrane adaptor, and N14F.
