Mutation of glutamate 155 of the GABAA receptor beta2 subunit produces a spontaneously open channel: a trigger for channel activation.

The Journal of neuroscience : the official journal of the Society for Neuroscience - 15 Dec 2004

Newell J Glen, McDevitt Ross A, Czajkowski Cynthia

Abstract excerpt

Protein movements underlying ligand-gated ion channel activation are poorly understood. The binding of agonist initiates a series of conformational movements that ultimately lead to the opening of the ion channel pore. Although little is known about local movements within the GABA-binding site, a recent structural model of the GABA(A) receptor (GABA(A)R) ligand-binding domain predicts that beta2Glu155 is a key...
