Recombinant human CLDN10 protein refers to a genetically engineered form of claudin-10 (CLDN10), a key component of tight junctions that regulate paracellular transport and cell polarity in epithelial and endothelial tissues. CLDN10 exists as two major splice variants (CLDN10a and CLDN10b), which exhibit distinct ion selectivity and tissue-specific expression. CLDN10a is primarily expressed in the kidney's thick ascending limb, where it facilitates paracellular chloride transport and contributes to urine concentration. CLDN10b, found in exocrine glands and the epidermis, regulates sodium permeability. Both isoforms maintain tissue barrier integrity and electrolyte homeostasis.
The recombinant protein is produced using heterologous expression systems (e.g., E. coli, mammalian cells) to enable controlled studies of CLDN10's structural and functional properties. Its production supports research into diseases linked to tight junction dysfunction, including renal tubular disorders, skin barrier defects, and autoimmune conditions. Notably, mutations in CLDN10 are associated with HELIX syndrome (Hypohidrosis, Electrolyte Imbalance, Lacrimal gland dysfunction), highlighting its clinical relevance. Recombinant CLDN10 also serves as a tool for drug screening, antibody development, and mechanistic studies of epithelial transport. Recent advancements in cryo-EM and crystallography using recombinant protein have begun revealing molecular details of claudin assembly and regulation.
