Figure 4. Model for exocyst complex that mediates secretion.

Figure 4

The exocyst is defined as a complex of 8 proteins (shaded green). Exo70 and Sec3 localize to the plasma membrane to define the future site of vesicle fusion. The other six exocyst proteins traffic along with the secretory vesicles. The eight members of the exocyst form a complex at the plasma membrane that activates the SNARE complex to promote vesicle fusion.
