Brain spectrin binding to the NMDA receptor is regulated by phosphorylation, calcium and calmodulin.

Abstract

The N-methyl-D-aspartate receptor (NMDA-R) and brain spectrin, a protein that links membrane proteins to the actin cytoskeleton, are major components of post-synaptic densities (PSDs). Since the activity of the NMDA-R channel is dependent on the integrity of actin and leads to calpain-mediated spectrin breakdown, we have investigated whether the actin… (More)
