What Does NIS Stand For?
NIS stands for Sodium Iodide Symporter
NIS, or Sodium Iodide Symporter, is a membrane protein that facilitates the active transport of iodide ions into cells, primarily in the thyroid gland. This process is essential for the synthesis of thyroid hormones, which regulate metabolism and overall physiological functions. NIS plays a crucial role in both normal thyroid function and the diagnosis and treatment of thyroid disorders, particularly in the context of radioactive iodine therapy for thyroid cancer.
