Recombinant Human CLDN16 Protein，His

CLDN16, or Claudin-16, is a member of the claudin family of tight junction proteins, which play a crucial role in maintaining the integrity of epithelial barriers and regulating paracellular transport. Its expression is primarily found in the kidney, particularly in the thick ascending limb of the loop of Henle, where it is essential for the reabsorption of divalent cations, such as magnesium and calcium. Mutations in the CLDN16 gene lead to a rare genetic disorder known as Familial Hypomagnesemia with Hypercalciuria and Nephrocalcinosis (FHHNC), which is characterized by low magnesium levels, high calcium levels in urine, and an increased risk of kidney stones. The study of CLDN16 and its recombinant protein is critical for understanding its functional mechanisms in cell junction integrity and ion transport. Recombinant CLDN16 protein can be used in various experimental studies to elucidate its role in tight junction dynamics, its interaction with other junctional proteins, and its contributions to renal pathophysiology. Furthermore, exploring potential therapeutic avenues for conditions arising from its dysfunction makes CLDN16 a protein of significant interest in both fundamental research and clinical applications. Understanding the structure and function of CLDN16 through recombinant protein studies could lead to novel strategies for managing related renal disorders and improving patient outcomes.
