glvI

Gene
glvI
Protein
Proton-gated ion channel
Organism
Gloeobacter violaceus (strain ATCC 29082 / PCC 7421)
Length
359 amino acids
Function
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.
Similarity
Belongs to the ligand-gated ion channel (TC 1.A.9) family.
Mass
40.986 kDa
