In the present work, various forms of human kallikrein-related peptidase 15 (KLK15) and its splice variant KLK15ntfl were produced in E.coli, purified and refolded. Fluorogenic substrate testings revealed a trypsin-like activity for mature KLK15, KLK15ntfl displayed no detectable activity. Furthermore, the production of the "natural" pro-enzyme of KLK15/KLK15ntfl allowed the analysis of potential KLK15-activators. The tested KLK-proteases (KLK4-8, 10, 11) however were not able to activate KLK15/KLK15ntfl via limited proteolysis.
