Brain Translation: A Feather Tips the Scale

摘要

In this issue of Molecular Cell, Gonatopoulos-Pournatzis et al. (2020) report a neuron-specific microexon in eIF4G translation initiation factors that dampens synaptic protein translation. Autism-associated disruption of this exon results in increased protein production, likely through reduced coalescence with cytoplasmic ribonucleoprotein granule components, including FMRP.
