A Truncated Isoform of Connexin43 Caps Actin to Organize Forward Delivery of Full Length Connexin43

Video summary by Rachel Baum and Vu Nguyen (University of Utah)
Description:
In this work, Baum and Nguyen et al discover that the same mRNA, which encodes the gap junction protein Connexin43, also encodes a smaller isoform (GJA1-20k) that binds directly to actin and arranges the cytoskeleton delivery apparatus for efficient delivery and localization of the larger Connexin43 membrane channel to its appropriate membrane subdomain.
Keywords:
Connexin43, GJA1-20k, mRNA, actin, microtubule, heart, arrhythmia, gap junctions, targeted delivery, forward delivery, membrane protein trafficking.
