Studies usingDrosophilahave been the trail blazer to unveil mechanisms underlying FMRP function and FXS, and many of these findings are confirmed in mammalian models. For example, the first identified FMRP mRNA target isFutsch, a homolog of mammalian microtubule associated protein 1B (MAP1B), whic...
