Novel regulatory site within the TM3-4 loop of human recombinant alpha3 glycine receptors determines channel gating and domain structure.

Abstract excerpt

Glycine receptors are Cys loop ligand-gated ion channels that mediate fast inhibitory synaptic transmission in the mammalian central nervous system. The functionally distinct splice variants alpha3L and alpha3K of the human glycine receptor differ by a 15-amino acid insert within the long intracellular TM3-4 loop, a region of high intersubunit diversity. In a mutational study, effects of the insert on ion channel...
