Kallikrein-related (KLK) recombinant proteins are engineered variants of the kallikrein enzyme family, which plays a critical role in physiological and pathological processes such as inflammation, tissue remodeling, and cancer progression. The KLK family consists of 15 serine proteases (KLK1-KLK15) encoded by the largest contiguous cluster of protease genes in the human genome. These enzymes regulate signaling pathways by cleaving substrates like kinins, growth factors, and extracellular matrix components. Dysregulation of KLKs is linked to diseases including neurodegenerative disorders, cardiovascular conditions, and metastatic cancers.
Recombinant KLK proteins are produced using expression systems like *E. coli*, yeast, or mammalian cells to ensure proper folding and post-translational modifications. Their production enables detailed study of substrate specificity, inhibitory mechanisms, and structure-function relationships. For example, KLK3 (prostate-specific antigen, PSA) is widely used as a biomarker for prostate cancer, while KLK5-KLK7 are studied in skin desquamation and inflammatory skin diseases. Recombinant forms allow standardized assays for diagnostics and drug development.
Recent research focuses on designing KLK inhibitors for therapeutic applications, particularly in oncology. Challenges include balancing enzyme specificity and avoiding off-target effects due to KLKs' overlapping substrate preferences. Advances in protein engineering, such as site-directed mutagenesis and fusion tags, have improved yield and functionality. KLK recombinant proteins also serve as tools to explore protease-activated receptors (PARs) and their role in cellular signaling.
Overall, KLK recombinant proteins bridge basic research and clinical translation, offering insights into disease mechanisms and opportunities for targeted therapies. Their versatility underscores their importance in both academic and biotechnological contexts.
