Further Information

Abbreviation:
SLPI
Accession:
P03973
Activity:
Measured by its ability to inhibit trypsin cleavage of a fluorogenic peptide substrate, Mca-RPKPVE-Nval-WRK (Dnp)-NH2 (Catalog # ES002). The IC50 value is < 1 Nm.
Background:
Secretory leukoprotease inhibitor (SLPI); also called antileukoprotease (ALP); is a 12-kDa; nonglycosylated serine protease inhibitor present in mucous secretions. 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.
Calculated MW:
13.1 kDa
