Long-term changes in synaptic plasticity require new protein synthesis. This preview discusses data from Kim et al. (this issues of Neuron) that demonstrate the requirement of a novel, nucleolar protein, LLP (LAPS18-like protein), for the formation of long-term facilitation in Aplysia. LLP binds to and transcriptionally activates C/EBP, thereby promoting the formation of long-term facilitation and behavioral sensitization.
突触可塑性的长期变化需要新的蛋白质合成。本综述讨论了Kim等人(本期《神经元》)的数据,这些数据表明一种新型核仁蛋白LLP(类LAPS18蛋白)对于海兔中长时程易化的形成是必需的。LLP与C/EBP结合并激活其转录,从而促进长时程易化和行为敏化的形成。
