Fragile X syndrome (FXS) is a leading cause of autism and neurons lacking FMRP show aberrant mRNA translation and intracellular signalling. Here, the authors show that neurons from Fmr1 knockout mice have increased levels of ADCY1 protein, producing abnormal ERK1/2 signalling, dysregulated protein synthesis and behavioural symptoms associated with FXS.
