Function
KLK7_MOUSE May catalyze 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. Cleaves insulin A chain at '14-Tyr-|-Gln-15' and insulin B chain at '6-Leu-|-Cys-7', '16-Tyr-|-Leu-17', '25-Phe-|-Tyr-26' and '26-Tyr-|-Thr-27'.

Publication Abstract from PubMed
A series of 1,3,6-trisubstituted 1,4-diazepan-7-ones were prepared as kallikrein 7 (KLK7, stratum corneum chymotryptic enzyme) inhibitors. Previously reported compounds 1-3 were potent human KLK7 inhibitors; however, they did not exhibit inhibitory activity against mouse KLK7. Comparison of the human and mouse KLK7 structures reveals the cause of this species differences; therefore, compounds that could inhibit both KLK7s were designed, synthesized, and evaluated. Through this structure-based drug design, compound 22g was identified as an inhibitor against human and mouse KLK7, and only one of the enantiomers, (-)-22g, exhibited potent inhibitory activity. Furthermore, the crystal structure of mouse KLK7 complexed with 22g enabled the elucidation of structure-activity relationships and justified 22g as a valuable compound to overcome the species differences.
