KRT6C, a member of the keratin type II family, is a structural protein critical for maintaining epithelial cell integrity. Encoded by the *KRT6C* gene, it forms intermediate filaments by pairing with type I keratins (e.g., KRT16/KRT17) to create a resilient cytoskeletal network. These filaments provide mechanical strength to epithelial tissues, particularly in high-stress regions like nails, hair follicles, and palmoplantar epidermis. KRT6C is dynamically regulated during wound healing and inflammation, where its overexpression supports rapid tissue repair.
Clinically, *KRT6C* mutations are linked to pachyonychia congenita (PC), a rare genetic disorder causing painful palmoplantar keratoderma and nail dystrophy. Dysfunctional KRT6C disrupts filament assembly, leading to cell fragility and pathological keratinization. Beyond genetic diseases, KRT6C is implicated in cancer progression, as its abnormal expression in carcinomas correlates with tumor invasion and metastasis.
Recombinant KRT6C protein is engineered using prokaryotic (e.g., *E. coli*) or eukaryotic expression systems to study its biochemical properties and disease mechanisms. Purified via affinity chromatography, the protein retains structural and functional features of native keratins. Researchers employ it to investigate keratin filament dynamics, screen therapeutic compounds for PC, or develop antibodies for diagnostic use. Its role in epithelial stress responses also makes it a biomarker candidate for inflammatory skin conditions. Despite challenges in solubility and aggregation-prone behavior, recombinant KRT6C remains a vital tool for deciphering keratin biology and advancing translational research in dermatology and oncology.
