Rabphilin-3A undergoes phase separation to regulate GluN2A mobility and surface clustering
Abstract
GluN2A and GluN2B, two predominant Glu2N subunits of NMDARs in hippocampus and cortex, display distinct organization and mobility in the neuronal surface. Here, authors show Rph3A, a GluN2A-specific binding protein, undergoes liquid-liquid phase separation, which regulate mobility, synaptic and extrasynaptic surface clustering, synaptic localization and synaptic response of GluN2A.
