SLC40A1 (Solute Carrier Family 40 Member 1)

SLC40A1, also known as ferroportin, is a protein that functions as the body's main iron transporter. Located on the surface of certain cells, especially in the intestines and immune system, it helps regulate how iron is absorbed from food and released into the bloodstream. Proper function of SLC40A1 is essential for maintaining healthy iron levels; if it malfunctions, it can lead to conditions like iron overload or deficiency. In essence, SLC40A1 controls the balance of iron in your body, ensuring enough iron is available for building blood and other vital functions.
