Localized translation and the requisite trafficking of the mRNA template play significant roles in the nervous system including the establishment of dendrites and axons, axon path-finding, and synaptic plasticity. We provide a brief review on the regulation of localizing mRNA in mammalian neurons through critical post-translational modifications of the(More)
The molecular mechanisms that govern the timing and fate of neural stem-cell differentiation toward the distinct neural lineages of the nervous system are not well defined. The contribution of post-transcriptional regulation of gene expression to neural stem-cell maintenance and differentiation, in particular, remains inadequately characterized. The(More)
During spermatogenesis, mRNA localization and translation are believed to be regulated in a stage-specific manner. We report here that the Protamine2 (Prm2) mRNA transits through chromatoid bodies of round spermatids and localizes to cytosol of elongating spermatids for translation. The transacting factor CBF-A, also termed Hnrnpab, contributes to temporal(More)
