Transport of connexons to the plasma membrane (R-HSA-190872) [Homo sapiens]


Following connexon oligomerization, the hemichannels must be transported to the plasma membrane. This has been shown to occur in transport vesicles called "cargo containers". Most of post-Golgi cargo containers have a diameter of of 50- 200 nm (Lauf et al., 2002). Recently direct transport of connexins to GJ assembly sides has been described (Shaw et al., 2007). Besides microtuble-dependent trafficking, a microtubule-independent delivery pathway may exist as concluded from studies using the secretory transport inhibitor, Brefeldin A (Musil and Goodenough 1993; De Sousa et al. 1993; Laird et al. 1995).
