Kallikrein Related Peptidase 7, Kallikrein 7 (Chymotryptic, Stratum Corneum), Stratum Corneum Chymotryptic Enzyme, Serine Protease 6, PRSS6, SCCE, HK7, Kallikrein-Related Peptidase 7, Signal Protein, EC 18.104.22.168, EC 3.4.21, HSCCE.
KLK7 catalyzes the degradation of intercellular cohesive structures in the cornified layer of the skin in the continuous shedding of cells from the skin surface. Specific for amino acid residues with aromatic side chains in the P1 position. KLK7 cleaves insulin B chain at ''6-Leu- -Cys-7'', ''16-Tyr- -Leu-17'', ''25-Phe- -Tyr-26'' and ''26-Tyr--Thr-27''. KLK7 is involved in the activation of precursors to inflammatory cytokines.
KLK7 produced in Sf9 Baculovirus cells is a single, glycosylated polypeptide chain containing 190 amino acids (1-181 a.a.) and having a molecular mass of 20.9kDa (Migrates at 28-40kDa on SDS-PAGE under reducing conditions).
KLK7 is expressed with a 6 amino acid His tag at C-Terminus and purified by proprietary chromatographic techniques.
Sf9, Baculovirus cells.
