The role of protein phosphatase‐1 in the modulation of synaptic and structural plasticity

Synaptic plasticity is a phenomenon contributing to changes in the efficacy of neuronal transmission. These changes are widely believed to be a major cellular basis for learning and memory. Protein phosphorylation is a key biochemical process involved in synaptic plasticity that operates through a tight balance between the action of protein kinases and protein phosphatases (PPs). Although the majority of research in this field has concentrated primarily on protein kinases, the significant role of PPs is becoming increasingly apparent. This review examines one such phosphatase, PP1, and highlights recent advances in the understanding of its intervention in synaptic and structural plasticity and the mechanisms of learning and memory.
