Target Type
Literature-reported
Target Bioclass
Transporter and channel
Family
Chloride channel (TC 2.A.49) family, ClC-3/CLCN3 subfamily
Subcellular location
Early endosome membrane; Golgi apparatus membrane
Function
[Isoform 1]: Strongly outwardly rectifying, electrogenic H(+)/Cl(-)exchanger which mediates the exchange of chloride ions against protons. The CLC channel family contains both chloride channels and proton-coupled anion transporters that exchange chloride or another anion for protons. The presence of conserved gating glutamate residues is typical for family members that function as antiporters.; [Isoform 2]: Strongly outwardly rectifying, electrogenic H(+)/Cl(-)exchanger which mediates the exchange of chloride ions against protons.
