CC   -!- FUNCTION: Component of the exocyst complex involved in the docking of
CC       exocytic vesicles with fusion sites on the plasma membrane during
CC       regulated or polarized secretion. Involved in polarized cell growth and
CC       organ morphogenesis. During cytokinesis, involved in cell plate
CC       initiation, cell plate maturation and formation of new primary cell
CC       wall.
CC   -!- SUBUNIT: The exocyst complex is composed of SEC3, SEC5, SEC6, SEC8,
CC       SEC10, EXO70A1 and EXO84B.
CC   -!- SIMILARITY: Belongs to the SEC3 family. {ECO:0000305}.
