The location and identity of homodimeric coiled-coil tethers (pink ovals) and multiple subunit tethering complexes (yellow rectangles) are shown, as well as some of the transport pathways and transport vesicles that are regulated by the membrane tethers. The majority of the coiled-coil protein tethers are associated with the Golgi apparatus, whereas the multiple subunit tethering complexes are found throughout the secretory and endolysosomal pathways.
