Crystal structure of GLIC with mutations at the loop C region
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
4ire is a 5 chain structure with sequence from Gloeobacter violaceus pcc 7421. Full crystallographic information is available from OCA.
