IREs are conserved cis-regulatory hairpin structures located within the 5’ or 3’ untranslated regions (UTRs) of target mRNAs. IRPs inhibit translation when bound to IREs within the 5’ UTR of mRNA encoding for proteins involved in iron storage, export, and utilization. IRP binding to multiple IREs within the 3’ UTR of transferin receptor 1 (TFR1) mRNA prevents its degradation, thereby augmenting translation of TFR1 and increasing iron uptake into cells. Dysregulation of IRPs has been associated with human cancers.\u003cbr\u003e\nIn iron replete cells, FBXL5 targets IRP2 for degradation. Under iron deficiency and\/or hypoxic conditions, FBXL5 is destabilized, resulting in IRP2 accumulation and interaction with IRE-containing mRNA.\u003c\/p\u003e\n\n\u003cp\u003ePurification and Purity: The antibody was purified by immunogen affinity chromatography.\u003c\/p\u003e\n\n\u003cp\u003eStorage and Stability: Store at 4°C short term.

Formalin-fixed cells were permeabilized with 0.1% Triton X-100 in TBS for 5-10 minutes and blocked with 3% BSA-PBS for 30 minutes at room temperature. Cells were probed with the primary antibody in 3% BSA-PBS and incubated overnight at 4 °C in a humidified chamber. Cells were washed with PBST and incubated with a AF488-conjugated secondary antibody (green) in PBS at room temperature in the dark. DAPI was used to stain the cell nuclei (blue).\u003c\/p\u003e\n\n\u003cp\u003eAlternative Name: Iron-responsive element-binding protein 2; IRE-BP 2; Iron regulatory protein 2; IRP2\u003c\/p\u003e\n\n\u003cp\u003eImmunogen: Recombinant protein corresponding to human IREB2.
