Resource competition controls the length-dependence of synaptic protein synthesis

A computational ribosomal regulation model shows that length-dependent synaptic protein synthesis shifts arise from a transition from initiation-limited to elongation-limited translation.

• Why it matters: Synaptic plasticity depends on protein availability, yet the mechanism linking protein length to differential synthesis during LTD is unclear.
• What they did: The authors built a computational model of ribosomal regulation and analyzed its dynamics to reproduce length-dependent expression changes observed during ribosomal elevations.
• The result: The model attributes the length-dependent shift to altered translation restriction, offering an explanation for how ribosomal control can be lost under pathological ribosome-enriched saturation.
