- 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.
