Function

Forms a channel that mediates water and glycerol transport across cell membranes at neutral pH . The channel is also permeable to urea . Plays an important role in body energy homeostasis under conditions that promote lipid catabolism; giving rise to glycerol and free fatty acids. Mediates glycerol export from adipocytes. After release into the blood stream; glycerol is used for gluconeogenesis in the liver to maintain normal blood glucose levels and prevent fasting hypoglycemia. Required for normal glycerol reabsorption in the kidney (By similarity).
