Fragile X protein acts as toggle switch in brain cells

New research shows how the protein missing in fragile X syndrome – the most common inherited form of intellectual disability – acts as a molecular toggle switch in brain cells.

The fragile X protein, called FMRP, hooks up with a group of molecules called microRNAs to switch the production of other proteins on and off in response to chemical signals, scientists at Emory University School of Medicine have discovered.
