WebOct 3, 2014 · Cellular iron homeostasis is regulated by post-transcriptional feedback mechanisms, which control the expression of proteins involved in iron uptake, release and storage. Two cytoplasmic proteins with mRNA-binding properties, iron regulatory proteins 1 and 2 (IRP1 and IRP2) play a central role in this regulation. WebMay 1, 2003 · Iron regulatory proteins (IRP) modulate the use of mRNA-encoding proteins that are involved in the transport, storage and use of iron. Several new potential mRNA targets for IRP were recently identified: divalent metal transporter-1 (DMT-1) and ferroportin, which are critical regulators of iron absorption in the gut and of iron cycling between ... WebOct 6, 2024 · The iron supply to the cells is controlled by the two proteins IRP-1 and IRP-2. If the cell lacks iron, IRP-1 and IRP-2 crank up the production of the various iron transporter... simply mortgage solutions
