RNA trafficking and translation in neurons John Carson
2
postsynaptic density RNA granule signaling synthesis CaMKII FMRP NG ARC PKM MAP1B MAP2 TOG hnRNP A2 RNA FMRP PSD and RNA granule constitute a bipartite positive feedback system to convert ephemeral electrical stimulation at the synapse into enduring biochemical changes in the spine RNA granule
3
translational output from individual RNA granules is bursty DHPG CaMKII FMRP NG PKM MAP1B MAP2 ARC
4
A2RE protein Stochastic simulation of bursty translation requires initiation rates > 0.3/s
5
CaMKII FMRP NG PKM MAP1B MAP2 ARC slow fast intact TOG protein is necessary and sufficient for granule assembly and bursty translation TOG is a structural catalyst for translation D1D2D3D4D5D6D7
