By deep sequencing ribosome-bound mRNA fragments, Sapkota et al. demonstrate non-canonical translation initiation and stop codon readthrough that diversify proteins in the mouse brain. They also show that neuronal stimulation regulates the choice of initiation sites, whereas gliotic diseases differentially regulate the levels of normal and readthrough AQP4 isoforms.
