Iron Transport Protein Regulation

Meaning

Iron Transport Protein Regulation is the physiological process governing the expression and function of key proteins responsible for moving iron across cellular membranes and throughout the systemic circulation. This regulation is critical for ensuring iron is delivered efficiently to all metabolically active tissues, including endocrine glands, and is safely sequestered when not needed. The primary proteins involved include transferrin, transferrin receptor, and ferroportin, all of which are tightly controlled by iron-responsive elements.
