Increased iodide permeability induced by TMEM16 proteins was sensitive to tannic acid. (A) Ionomycin-induced iodide permeability (Ipionomycin) from TMEM16E-CFP-CAAX (T16E)-, TMEM16H-CFP-CAAX (T16H)- or TMEM16J-CFP-CAAX (T16J)-expressing HEK293 cells was measured under control (con) or after pre-incubation with tannic acid (TA, 20 µM) for 3 min. (B) ATP-induced iodide permeability (IpATP) of TMEM16K-CFP-CAAX was measured under control (con) or after pre-incubation with tannic acid (TA, 20 µM) for 3 min. (Number of cells measured), § unpaired t-test, α < 0.05.
