Postsynaptic RIM1 modulates synaptic function by facilitating membrane delivery of recycling NMDARs in hippocampal neurons

Rab3-interacting molecules (RIMs) are a key component of the presynaptic active zone that regulate neurotransmitter release. Here, the authors show that RIM1 also has postsynaptic function to organize NMDA receptors and synaptic response.
