**Background of PCDH15 Recombinant Protein**
Protocadherin-15 (PCDH15), a member of the cadherin superfamily, is a critical transmembrane protein involved in cell-cell adhesion and mechanosensory signaling. It is predominantly expressed in sensory hair cells of the inner ear and photoreceptor cells of the retina, where it plays essential roles in maintaining structural integrity and facilitating sensory transduction. PCDH15 is particularly notable for its contribution to the formation of tip links, filamentous structures that connect stereocilia in hair cells and are vital for converting mechanical sound waves into electrical signals. Mutations in the *PCDH15* gene are linked to Usher syndrome type 1F (USH1F), a severe genetic disorder characterized by congenital deafness, vestibular dysfunction, and progressive vision loss, as well as non-syndromic hearing loss.
Recombinant PCDH15 protein is engineered to study its molecular interactions, structural features, and functional mechanisms. Typically produced using mammalian or insect expression systems, the recombinant protein retains post-translational modifications critical for its biological activity. Researchers utilize it to investigate PCDH15’s role in hair cell development, its binding partners (e.g., cadherin-23. CDH23), and its involvement in USH1F pathogenesis. Additionally, recombinant PCDH15 serves as a tool for developing gene therapies or molecular interventions aimed at restoring auditory and visual function in affected individuals. Its applications extend to high-throughput drug screening, antibody development, and structural biology studies to map domains essential for tip-link assembly.
Current research focuses on leveraging recombinant PCDH15 to explore therapeutic strategies, including viral vector-mediated gene delivery in preclinical models, to address underlying genetic defects in Usher syndrome. This protein thus bridges basic research and translational medicine, offering insights into sensory biology and potential treatments for hereditary hearing and vision disorders.
