Importantly, granule contents are also released according to a hierarchy, with secretory granules being the most readily exocytosed and azurophil granules only undergoing partial exocytosis [38].
The class II PI3K-C2a (C2a) is involved in endo- and exocytosis as well as endocytic recycling, whereas PI3K-C2 (C2) has been implicated in cell migration.

Subsequent studies showed that glucose-sensing mechanisms in the [beta]-cells are divided into the two components [70]: (1) Proximal events of glucose entry and metabolism, (2) the distal mechanisms of insulin secretion, spanning from mitochondrial signal generation and initiation of electrical activity to the ultimate effectors of [beta]-granule exocytosis.
AQP7 is expressed in pancreatic [beta]-cells and recently described as being involved in the regulation of insulin secretion and release by allowing the entry or exit of glycerol and by acting directly or indirectly at a distal downstream site in the insulin exocytosis pathway.
In accordance with this variable effect, cortical granules exocytosis has been reported in Xenopus oocytes [44] but not in porcine oocytes [46].
It produces hypoglycemic effects through an unwanted physical mechanism, rather than a physiological one that is by stimulating exocytosis by regulated pathway.
