Each monomer of the ANO2 dimer contains a pore that translocates chloride ions according to the concentration gradient from the cytosol to the extracellular region (Stöhr et al. 2009, and inferred from mouse homologs). Binding of calcium ions to sites in a transmembrane helix of each monomer increases the permeability of the pore to chloride ions.
