The resting-state conformation of the GLIC ligand-gated ion channel
Function
[GLIC_GLOVI] Cationic channel with similar permeabilities for Na(+) and K(+), that is activated by an increase of the proton concentration on the extracellular side. Displays no permeability for chloride ions. Shows slow kinetics of activation, no desensitization and a single channel conductance of 8 pS. Might contribute to adaptation to external pH change.[1]
About this Structure
4npq is a 20 chain structure. Full crystallographic information is available from OCA.
