General annotation (Comments)

Function

Slowly voltage-gated channel mediating the exchange of chloride ions against protons. Functions as antiporter and contributes to the acidification of the lysosome lumen. Ref.3 Ref.4

Subunit structure

Chloride channel 7 are heteromers of alpha (CLCN7) and beta (OSTM1) subunits. Ref.3

Subcellular location

Lysosome membrane; Multi-pass membrane protein Ref.3.

Disruption phenotype

Accumulates undegraded endocyted material in neurons or renal proximal tubular cells. Almost all ClC-7-deficient neurons die. Ref.4

Miscellaneous

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 By similarity.

Sequence similarities

Belongs to the chloride channel (TC 2.A.49) family. ClC-7/CLCN7 subfamily. [View classification]

Contains 2 CBS domains.
