Tales of tethers and tentacles: golgins in plants

Protein transport through the Golgi apparatus
cc JCB

As plant Golgi bodies move through the cell along the actin cytoskeleton, they face the need to maintain their polarized stack structure whilst receiving, processing and distributing protein cargo destined for secretion. Structural proteins, or Golgi matrix proteins, help to hold cisternae together and tethering factors direct cargo carriers to the correct target membranes. This review focuses on golgins, a protein family containing long coiled-coil regions, summarises their known functions in animal cells and highlights recent findings about plant golgins and their putative roles in the plant secretory pathway.
