O'Grady et al., Genève, Switzerland. In Prog Biophys Mol Biol, 2007
In this review, we discuss evidence supporting interactions between Cx and membrane channels/transporters including CFTR, aquaporins, ionotropic glutamate receptors, and between pannexin1, another class of putative gap-junction-forming proteins, and Kvbeta3, a regulatory beta-subunit of voltage gated potassium channels.
