Local functions for FMRP in axon growth cone motility and activity
... FMRP has been shown to associate with mRNAs that encode proteins regulating the cytoskeleton and synapses. One such FMRP target is the microtubule associated protein (MAP1b) mRNA, which is inappropriately translated in both Drosophila dFmr1 (dfxr) null (Zhang et al., 2001a,b; Pan et al., 2004) and m ...
