PIST couples actin cytoskeleton dynamics through a WH2-like actin-binding domain.
Purkinje cell synapses in the cerebellar cortex require tight coordination between receptor trafficking and cytoskeletal remodeling to sustain synaptogenesis, structural plasticity, and motor learning. The glutamate δ2 receptor (GluRδ2), a hallmark component of parallel fiber-Purkinje cell synapses, depends on intracel...
