Product Background

SMR3B (P-B, PRL3, PROL3), namely submaxillary gland androgen regulated protein 3B, is a proline-rich protein specifically expressed in salivary glands. The SMR3B is an 8.188 kilodalton protein that belongs to the gene family whose other members are SMR3A and PROL1, which all produce opiorphin homologs. It is predicted to enable endopeptidase inhibitor activity and be involved in cellular response to lipopolysaccharide. SMR3B also regulates pain perception.
