1.A.24.1.12
Connexin 29 (Cx29, Gjc3, Gje1) of 269 aas and 4 TMSs.  The Cx29E269D mutant has a dominant negative effect on the formation and function of gap junctions, explaining the role Cx29 in the development of hearing loss (Hong et al. 2010).  Direct axon-to-myelin linkage by abundant KV1 (TC# 1.A.1.2.10 and 12)/Cx29 channel interactions in rodent axons supports the idea of an electrically active role for myelin in increasing both the saltatory conduction velocity and the maximal propagation frequency in mammalian myelinated axons (Rash et al. 2016).
