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).

Detection of Kallikrein 7 by Western Blot
KLK7 is involved in the A beta degradation activity Inhibition of A beta degradation activity of CCF‐STTG1 cells with MAB2624, a KLK7‐neutralizing antibody. Quantification of the relative remaining A beta 40 and A beta 42 in a mixture of normal culture medium and conditioned medium is shown below the blot (n = 3, mean ± s.e.m., *P < 0.05 by Student's t‐test).Dose‐dependent inhibition of A beta degradation activity of CCF‐STTG1 cells with MAB2624. Quantification of relative remaining A beta 40 in the mixture of normal culture medium and conditioned medium is shown below the blot (n = 3, mean ± s.e.m., **P < 0.01 by Tukey's test).A beta degradation activity in the conditioned medium of COS‐1 cells expressing human KLK7. Quantification of relative remaining A beta 40 in the mixture of normal culture medium and conditioned medium is shown below the blot (n = 3, mean ± s.e.m., ***P < 0.001 by Tukey's test).A beta degradation activity of the recombinant KLK7 protein. Immunoblot analysis of the remaining A beta in the mixture of normal cultured medium and conditioned medium of 7PA2 cells, and recombinant human KLK7 and KLK6 protein is shown. In vitro degradation of preformed A beta fibril by purified MBP‐tagged hKLK7 protein. Amounts of A beta fibrils were measured by thioflavin T fluorescence, and relative fluorescence levels at each time point were shown (n = 3, mean ± s.e.m., *P < 0.05, **P < 0.01 by Tukey's test).Source data are available online for this figure.
