The Structural Basis of Iron Sensing by the Human F-box Protein FBXL5.
Chembiochem. 2012 Apr 16;13(6):788-91. doi: 10.1002/cbic.201200043.
Iron sensing: The F-box and leucine-rich repeat containing protein FBXL5 is an iron sensor that regulates the ubiquitination of iron regulatory protein IRP2. Crystal structures of the iron-sensing hemetrythrin (Hr)-like domain of human FBXL5 (FBXL5 Hr) were determined in oxidized and reduced states. These structures revealed the mechanisms of iron sensing by FBXL5.
