Elucidation of the structures of native GABA A receptors in complex with auxillary proteins


EMSL Project ID
51200

Abstract

The objectives of this research are to elucidate the structures of mammalian neurotransmitter receptors by single particle cryo-EM in multiple distinct conformational states in which the receptors are bound with selected agonists, antagonists, allosteric modulators and/or ion channel pore blockers. We will also elucidate the structures of neurotransmitter receptors in complexes with auxiliary proteins that modulate receptor activity. The proposed studies will focus on ionotropic glutamate receptors. These studies will not only reveal the overall architectures and structures of neurotransmitter receptors and their complexes with auxiliary proteins but they will also provide detailed, structure-based insight into their mechanisms of action.
