Abstract
Fragile mental retardation protein (FMRP), encoded by the FMR1 gene, has been detected in pre- and postsynaptic neuronal processes. It plays central roles in translational repression of several dendritic mRNAs, which have translation activated upon synaptic stimulation, notably by glutamate. Other DNA- and RNA-mediated roles have been assigned to FMRP. Different FMRP isoforms have been proposed due to FMR1 transcript alternative splicing and protein electrophoretic gel mobility variations. However, a limited number of specific functional roles have been experimentally demonstrated for FMRP isoforms. In this proposal, we aim to understand the generation of functional diversity by FMR1 alternative splicing. (AU)
