The effect of permeating ion on TASK‐1 channel current reversal potential

2.5 mm K 25 mm K 25 mm Cs 25 mm Rb
TASK‐1 –73 ± 2 (= 13) –38 ± 1 (= 10) –64 ± 2 (= 8) –41 ± 3 (= 7)
TASK‐1_G106R –33 ± 8 (= 5) –28 ± 4 (= 5) –29 ± 5 (= 5) –25 ± 3 (= 5)
TASK‐1_L214R –19 ± 3 (= 5) –17 ± 2 (= 5) –18 ± 4 (= 5) –15 ± 3 (= 5)
GFP alone –32 ± 2 (= 13) –25 ± 3 (= 6) –31 ± 4 (= 5) –27 ± 3 (= 5)

Reversal potentials (in mV) obtained for TASK‐1, TASK‐1_G106R, TASK‐1_L214R and GFP alone transfected cells when the external solution contained 2.5 mm K, 25 mm K, 25 mm Cs or 25 mm Rb.
