Description | The Exo70 protein forms one subunit of the exocyst complex (consist of Sec3, Sec5, Sec6, Sec8, Sec10, Sec15, Exo70, and Exo84 in budding yeast). First discovered in Saccharomyces cerevisiae [ ], it is evolutionarily conserved in eukaryotes. It mediates the tethering of post-Golgi secretory vesicles to the plasmamembrane and promotes the assembly of the SNARE complex for membrane fusion. It also plays a role in cell polarisation, primary ciliogenesis, cytokinesis, pathogen invasion, tumourigenesis and metastasis [ ]. It is a member of the the Complex Associated with Tethering Containing Helical Rods (CATCHRs) family which also includes Conserved Oligomeric Golgi complex (COG) and Golgi-Associated Retrograde Protein complex (GARP) and DSL1 complexes, all evolutionarily related and share structural features consisting of α-helical bundles at the C terminus and coiled-coil region at the N terminus [, , , ]. Exo70 interacts with phospholipids the Rho3 GTPase [, ]. This interaction with Rho3 mediates one of the three known functions of Rho3 in cell polarity: vesicle docking and fusion with the plasma membrane (the other two functions are regulation of actin polarity and transport of exocytic vesicles from the mother cell to the bud) []. |
