Proton-gated chloride channel

Two histamine-gated chloride chatmd subunits (HisQl and HisCl2, Fig. 29.5.3) expressed in Drosophila eye both contain T at position 2 and are insensitive to PTX and fipronil [58]. In addition, two novel proton-gated chloride channel subunits in this family (pHClA, B and C in Fig. 29.5.3), of unknown function, both contain M at position 2 and are also insensitive to PTX and fipronil [59].
