The FET family proteins FUS, EWSR1 and TAF15 are RNA-binding proteins with diverse nuclear functions. PAR-CLIP analyses now reveal the genome-wide RNA targets of all three human FET proteins and of two FUS mutants that cause amyotrophic lateral sclerosis. Although the RNA-binding properties of the mutants remain unchanged, the spectrum of RNA targets is altered because of the changed subcellular localization of the mutants.
