title: Modulation of neuronal protein trafficking and function by palmitoylation.
abstract: Modification of proteins with the lipid palmitate regulates targeting to specific vesicular compartments and synaptic membranes. Mounting evidence indicates that this lipid modification modulates diverse aspects of neuronal development and synaptic transmission. In particular, palmitoylation regulates the function of proteins that control neuronal differentiation, axonal pathfinding and filopodia formation. In addition, trafficking of numerous proteins associated with synaptic vesicle release machinery requires protein palmitoylation. Remarkably, reversible palmitoylation of specific scaffolding proteins and signaling molecules dynamically regulates ion channel clustering and synaptic strength. The recent discovery of enzymes that palmitoylate specific subsets of synaptic proteins suggests that this process is tightly controlled in neurons.
