Anti-SLURP2 antibodies are used in the immunodetection of the protein secreted LY6/PLAUR domain containing 2. In humans, the canonical protein has a reported length of 97 amino acid residues and a mass of 10.2 kDa. It has been described to be a secreted protein. It is reported to be expressed at highest levels in cervix and esophagus, followed by adult and fetal skin. SLURP2 is known to bind and may modulate the functional properties of nicotinic and muscarinic acetylcholine receptors. Synonyms for this target antigen include secreted LY6/PLAUR domain-containing protein 2, secreted Ly-6/uPAR-related protein 2, secreted Ly6/uPAR related protein 2, and secreted Ly-6/uPAR domain-containing protein 2. SLURP2 gene orthologs have been reported in the mouse and rat species.
