Membrane currents without SpIH expression. (A) Im responses from HeLaCx43 cell lacking expression of SpIH to hyperpolarizing pulses recorded in Ca2+-free KAsp solution. (B) Perfusion with the Ca2+-free KAsp external solution did not induce currents in HeLaCx43 cells that were not transfected with SpIH (0.4 ± 0.1 pA/pF, n = 5).
