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 Kallikrein 7 consists of 253 amino acids (aa), with a signal peptide (aa 1-22), short pro peptide (aa 23-29) and mature chain (aa 30-252) (1). Predominantly expressed in the skin, a major physiological function of Kallikrein 7 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 Kallikrein 7 is Kallikrein 5, another member of the human tissue Kallikrein family. Along with Kallikrein 14, these three Kallikreins form a proteolytic cascade in the stratum corneum (5).
