Abstract

Targeting of messenger RNAs (mRNAs) in neuron processes relies on cis-acting regulatory elements, the nature of which is poorly understood. Here, we report that approximately 30% of the best-known dendritic mRNAs contain a guanine (G)quadruplex consensus in their 3-2-untranslated region. Among these mRNAs, we show by using RNA structure probing that a Gquadruplex is present in the mRNAs of two key postsynaptic proteins: PSD-95 and CaMKIIa. The Gquadruplex structure is necessary and sufficient for the potent and fast localization of mRNAs in cortical neurites and this occurs in a metabotropic glutamate receptor-responsive manner. Thus, Gquadruplex seems to be a common neurite localization signal.
