Function
function
Component of the exocyst complex involved in the docking of exocytic vesicles with fusion sites on the plasma membrane during regulated or polarized secretion. Involved in polarized cell growth and organ morphogenesis. During cytokinesis, involved in secretory processes during cell plate initiation, cell plate maturation and formation of new primary cell wall.
Participates in polarized pectin delivery required for the polarized development of the mucilage-producing volcano cells of the seed coat.
