The primary aim of this project was to recombinantly produce and purify synthetic pro-enzyme forms of three human proteases: KLK4, KLK8 and KLK15. The pro-peptide harbors a histidine6-tag, which can be used for purification followed by an enterokinase cleavage site. After activation of the purified and refolded proteins by enterokinase,the resulting mature enzymes should be biochemically analyzed.
In the case of KLK15, a splice variant (KLK15 ntfl) exsists, which is expressed in ovarian cancer. This variant was to be produced and purified and investigated for its potential enzymatic activity.
Finally, it was planned to expand the existing knowledge concerning the (patho-) physiological role of KLK4, KLK8, and KLK15, especially with regard to their interaction with potential cancer-related targets, such as the urokinase-type plasminogen activator (uPA) and proteinase-activated receptors (PARs).
