TMEM16A (ANO1) is a calcium-activated chloride channel: heterologous expression produces Ca2+-activated Cl- currents with biophysical and pharmacological properties matching native CaCC currents; knockdown of mouse Ano1 markedly reduced native Ca2+-activated chloride currents and saliva production in mice. |

TMEM16A localizes to apical membranes of epithelial cells in exocrine glands and trachea, to airway and reproductive-tract smooth muscle cells, and to interstitial cells of Cajal (ICC) in the GI tract (but not GI smooth muscle); TMEM16A knockout mice show diminished rhythmic gastric smooth muscle contraction, establishing its role as the pacemaker CaCC in ICC. |

ANO1/TMEM16A channels in arterial myocytes are activated by membrane stretch (cell swelling/pressure) via a local Ca2+ signal generated by nonselective cation channels (blocked by Gd3+ and SKF-96365, but not by L-type Ca2+ channel blocker nimodipine or store-depletion with thapsigargin); TMEM16A knockdown reduced pressure-induced membrane depolarization and vasoconstriction (myogenic response) without altering K+-induced constriction. |
