Iron regulatory proteins -1 and -2 (IRP1, IRP2) are homologous cytoplasmic RNA-binding proteins that controls cellular iron metabolism and maintain systemic iron homeostasis in vertebrates along with serving some additional iron-independent functions. IRP2 belongs to aconitase/IPM isomerase family and it binds to IRES (iron-responsive elements), which are stem-loop structures found in 5'-UTR of ferritin, and delta aminolevulinic acid synthase mRNAs, and in the 3'-UTR of transferrin receptor mRNA. IRP2-IRE binding results in the repression of its mRNA translation and its binding to transferrin receptor mRNA inhibits the degradation of this otherwise quickly degradable mRNA. IRP2 is a substrate of FBXL5, an F-box protein that assembles together with Skp1, Cul1 and Rbx1 into an E3 ubiquitin ligase complex. When iron/O2 are high, IRP2 gets ubiquitinated/degraded by SCF complex containing FBXL5, whereas under conditions of low iron/O2, FBXL5 is degraded preventing IRP2 ubiquitination leading to its RNA-binding activity. IRP2 deficient mice depicts microcytosis, misregulated iron metabolism (in CNS, intestine as well as liver associated with FTH1 and FTL up-regulation) and iron deficiency in splenic macrophages associated with down-regulation of FTH1, FTL, and FPN1.
