Hepcidin fpn
Ferroportin-1, also known as solute carrier family 40 member 1 (SLC40A1) or iron-regulated transporter 1 (IREG1), is a protein that in humans is encoded by the SLC40A1 gene, and is part of the Ferroportin (Fpn) Family (TC# 2.A.100). Ferroportin is a transmembrane protein that transports iron from the inside of a cell to the outside of the cell. Ferroportin is the only known iron exporter. WebT.A. provided fluorescently labeled hepcidin and anti-FPN antibodies for structure determination. A.M. built and refined models of FPN and Fab45D8. The manuscript was written by C.B.B., C.M.A., Y.C., and A.M. with revisions provided by all authors. The overall project was supervised by Y.C. and A.M.

WebHepcidin, a hepatocyte-derived hormone, is a key regulator of body iron homeostasis. More specifically, hepcidin reduces iron efflux from intracellular iron by binding to ferroportin (FPN), a cellular iron exporter, and induces its internalization and degradation. WebThe negatively charged Asp325 residue has proved to be essential for iron export by human (HsFPN1) and primate Philippine tarsier (TsFpn) ferroportin, but its exact role during the iron transport cycle is still to be elucidated. It has been posited as being functionally equivalent to the metal ion-coordinating residue His261 in the C-lobe of the bacterial homolog BbFpn, …
Web9 jun. 2024 · This effect of hepcidin is largely due to its role of downregulating FPN expression in BMMs or OC precursors (Fig. 5), as suppressing FPN expression in …
WebIron is essential for cell survival and function. It is a transition metal, that could change its oxidation state from Fe2+ to Fe3+ involving an electron transfer, the key of vital functions but also organ dysfunctions. The goal of this review is to WebExpression of ferroportin (Slc40a1, alias Fpn), heme oxygenase-1 (Hmox1), H- and L-ferritin (Fth1 and Ftl1), hepcidin (Hamp), ceruloplasmin (Cp) and interleukine-6 (Il6) was followed by quantitative PCR. FPN and HMOX1 protein expression was analyzed by immunofluorescence and in-cell-Western blotting.
