Long-term editing of brain circuits using an engineered electrical synapse

Design of the Cx34.7 and Cx35 mutant library A semi-rational design approach was used to design the mutant library. Sequence alignments between the M. americana connexins and the connexins for which the most structure–function data existed (Cx26, Cx32, Cx36, Cx40 and Cx43) were performed in ClustalW. Sites identified by previous studies as conferring specificity for docking were used, as well as those identified by homology modelling from the structures of Cx26 (ref. 56 ). …
