It is thought to play a role in protecting the mucosae from injury associated with inflammation. SLPI is locally produced by serous cells; including bronchial submucosal glands. Elafin and SLPI are members of larger families of proteins secreted predominantly at mucosal sites; and have been shown to be modulated in multiple pathological conditions. Elafin and SLPI are structurally related in that both have a fold with a four-disulfide core or whey acidic protein (WAP) domain responsible for inhibiting proteases. SLPI is a prominent innate immune protein of the respiratory tract; possessing serine protease inhibitor activity; antibacterial activity; and anti-inflammatory\/immunomodulatory activity.\u003c\/p\u003e\n\n\u003cp\u003eActivity: Measured by its ability to inhibit trypsin cleavage of a fluorogenic peptide substrate, Mca-RPKPVE-Nval-WRK (Dnp)-NH2 (Catalog # ES002).
