**Background of KLK14 Recombinant Protein**
Kallikrein-related peptidase 14 (KLK14) is a serine protease belonging to the human tissue kallikrein family, which comprises 15 members (KLK1-KLK15). These enzymes play diverse roles in physiological and pathological processes, including skin desquamation, neural plasticity, inflammation, and cancer progression. KLK14 is encoded by the *KLK14* gene located on chromosome 19q13.4. a region densely clustered with other KLK genes. It is expressed in various tissues, such as the skin, prostate, and central nervous system, and is regulated by steroid hormones, cytokines, and epigenetic factors.
KLK14 exhibits trypsin-like enzymatic activity, cleaving substrates after arginine or lysine residues. It participates in proteolytic cascades, often interacting with other kallikreins and extracellular matrix components. Notably, KLK14 is implicated in pathological conditions, including psoriasis, neurodegenerative diseases, and cancers. In oncology, it is overexpressed in prostate, ovarian, and breast cancers, where it promotes tumor invasion, angiogenesis, and metastasis by activating protease-activated receptors (PARs) or modulating growth factor signaling.
Recombinant KLK14 protein is produced using engineered expression systems (e.g., *E. coli*, mammalian cells) to enable functional studies. Its recombinant form allows researchers to investigate substrate specificity, inhibitor interactions, and structural features. Purification often involves affinity tags (e.g., His-tag) and refolding steps to ensure enzymatic activity. Studies using recombinant KLK14 have highlighted its potential as a diagnostic biomarker or therapeutic target. For example, KLK14 inhibitors are being explored to block cancer-associated proteolysis, while its expression levels correlate with disease prognosis.
Despite progress, KLK14's full biological scope remains unclear. Ongoing research focuses on elucidating its role in tissue-specific pathways and diseases, leveraging recombinant protein tools to decode its mechanisms and therapeutic relevance.
