F box and leucine rich repeat protein 5, F box/LRR repeat protein 5, F-box and leucine-rich repeat protein 5, F-box protein FBL4/FBL5, F-box/LRR-repeat protein 5, FBL4, FBL5, FBXL5, FBXL5_HUMAN, FLR1, p45SKP2 like protein, p45SKP2-like protein.
Component of some SCF (SKP1-cullin-F-box) protein ligase complex that plays a central role in iron homeostasis by promoting the ubiquitination and subsequent degradation of IREB2/IRP2. Upon high iron and oxygen level, it specifically recognizes and binds IREB2/IRP2, promoting its ubiquitination and degradation by the proteasome. Promotes ubiquitination and subsequent degradation of DCTN1/p150-glued.
