Evolution of glutamate interactions during binding to a glutamate receptor

Qing Cheng , Mei Du , Gomathi Ramanoudjame & Vasanthi Jayaraman

Glutamate receptors are the predominant mediators of excitatory synaptic signals in the central nervous system and are important in learning and memory as well as in diverse neuropathologies including epilepsy and ischemia. Their primary function is to receive the chemical signal glutamate (1), which binds to an extracellular domain in the receptor, and convert it into an electrical signal through the formation of cation-permeable transmembrane channels.
