Component of the exocyst complex involved in the delivery of secretory vesicles to the plasma membrane. Also required for polarized cell growth and division septum assembly. The exocyst complex plays an important role in the targeting of rho3, as well as the two main hydrolases required for cell separation, eng1 and agn1, to the cell wall surrounding the septum before cell separation begins. Component of the exocyst complex composed of sec3, sec5, sec6, sec8, sec10, sec15 and exo70. Associated with the actinomyosin ring at the division site and at the cell tips.
