Background: Kallikrein 7

Human tissue Kallikrein 7 (hK7), also known as stratum corneum chymotryptic enzyme (SCCE), is a member of the human tissue kallikrein family. Full-length hK7 consists of 253 amino acids, with a signal peptide (residues 1-22), short pro peptide (residues 23-29) and mature chain (residues 30-252) (1). Predominantly expressed in the skin, a major physiological function of hK7 is to regulate the desquamation process through proteolysis of the intercellular adhesive structures between corneocytes (2). Thus, it is related to some inflammatory skin diseases, such as psoriasis and chronic itchy dermatitis (3, 4). Studies have shown that one potential physiological activator for hK7 is hK5, another member of the human tissue Kallikrein family. Along with hK14, these three kallikreins form a proteolytic cascade in the stratum corneum (5). The purified, secreted rhK7 corresponds to the pro form. When activated by thermolysin, it displays enzymatic activity towards a fluorogenic synthetic peptide described in the Activity Assay Protocol. This activity can be inhibited by rhSerpin A1, A3, A4, and A5 (R&D Systems, Catalog # 1268‑PI, 1295-PI, 1669-PI, and 1266-PI).
