Synaptic functional regulator FMR1 (FMR1)

Multifunctional polyribosome-associated RNA-binding protein that plays a central role in neuronal development and synaptic plasticity through the regulation of alternative mRNA splicing, mRNA stability, mRNA dendritic transport and postsynaptic local protein synthesis of a subset of mRNAs (PubMed:16631377, PubMed:18653529, PubMed:19166269, PubMed:23235829, PubMed:25464849). Plays a role in the alternative splicing of its own mRNA (PubMed:18653529).

Plays a role in mRNA nuclear export (By similarity). Together with export variable NXF2, is involved in the regulation of the NXF1 mRNA stability in neurons (By similarity).
