Gap junction channels span the membranes of two adjacent cells and allow the gated transit of molecules as large as second messengers from cell to cell. The structure of the gap junction channel pore is not resolved. For identification of pore determinants we used a chimera of two connexins, cx46 and cx32E(1)43, that form membrane channels with distinct(More)
Gap junction channels are intercellular channels that mediate the gated transfer of molecules between adjacent cells. To identify the domain determining channel conductance, the first transmembrane segment (M1) was reciprocally exchanged between Cx46 and Cx32E(1)43. The resulting chimeras exhibited conductances similar to that of the respective M1 donor.(More)
