I am interested in the molecular basis of cognition, which I study using fragile X syndrome as a model system. Fragile X syndrome (FXS) is caused by the absence of expression of the fragile X mental retardation protein FMRP, which is encoded by the FMR1 gene. FMRP is an RNA binding protein that binds ~4% of brain RNAs and regulates their translation. I am focused on understanding how FMRP regulates translation of its bound RNAs. I collaborate with Roberto Galvez at the Beckman Institute in studying the behavioral and spine phenotype in Fmr1 knockout mice to gain insight into the neuronal deficits underlying FXS. My group has discovered a novel helicase MOV10 that associates with FMRP and facilitates translation regulation of commonly bound RNAs (Kenny et al, Cell Reports 2014). To gain insight into MOV10 function in brain, we are creating a MOV10 knockout mouse. We will characterize the behavior of this mouse by collaborating with Justin Rhodes. One of the great intellectual advantages of my association with the Beckman Institute is my association with the Neuroscience program. This affiliation has greatly enhanced my development as a neuroscientist.
