Gene Information

General description

SLC40A1 (also known as ferroportin, FPN1), also called iron-regulated transporter 1 (IREG1), is an iron transporter expressed in liver, duodenum and kidney. SLC40A1 is also expressed in the brain, duodenal mucosa, in neuronal cells and endothelial cells of the blood-brain barrier.

Immunogen

synthetic peptide corresponding to an internal sequence of human SLC40A1, conjugated to KLH.

Application

Anti-SLC40A1 antibody produced in rabbit has been used in western blotting and immunohistochemistry.

Biochem/physiol Actions

Ferroportin 1(FPN1) plays a central role in systemic iron homeostasis and is critical for normal intestinal iron absorption. SLC40A1 is essential for development of the mouse embryo, forebrain patterning and neural tube closure. Hepcidin binds to and inhibits solute carrier family FPN1, thus preventing enterocytes of the intestines from secreting iron into the hepatic portal system, thereby functionally reducing iron absorption. Ferroportin in neuronal cells is required for cellular Fe2+ export, a process critical for normal neuronal function. It has been shown to interact with amyloid precursor protein (APP), to facilitate the iron export process from neuronal cells. Mutations in the FPN1 gene have been linked to hereditary hemochromatosis, a common disorder characterized by iron overload and multi-organ damage.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.
