The fragile X mental retardation protein FMRP is required for normal cognition: when it is absent, the most common form of inherited mental retardation, fragile X syndrome (FXS) results. Thus, FMRP is a molecular entry point for understanding normal neuronal function. FMRP is an RNA binding protein that binds ~4% of brain mRNAs and regulates their expression—either enhancing or suppressing translation by an unknown mechanism. Many of the mRNAs that bind FMRP have been identified; however, it is still unknown how FMRP regulates their translation. Our long-term goal is to uncover the mechanism of FMRP-mediated translation regulation, exploring both associated proteins and microRNAs.
