11. In neuronal and neuroendocrinal cells, this mostly occurs via regulated exocytosis . 12. Because of this function, the exocyst complex is heavily involved in exocytosis . 13. DNAJC5 appears to have a role in stimulated exocytosis . 14. The endocytosis mechanism is slower than the exocytosis mechanism. 15. Cortical granule exocytosis has been shown to occur directly following a calcium wave. 16. It is one of the components of a multiprotein complex required for exocytosis . 17. Vacuoles do not have catabolic activity and do not undergo exocytosis as lysosomes do. 18. Endocytosis is the reverse of exocytosis and can occur in a variety of forms. 19. Complexins stabilize the primed SNARE-complex rendering the vesicles ready for rapid exocytosis . 20. Syntaxin-1A is a key protein in ion channel regulation and synaptic exocytosis .
