Novel function of transthyretin in pancreatic alpha cells.

abstract：:The plasma membrane (PM) sphingolipid composition is the result of a series of well-known metabolic pathways comprising neobiosynthesis in the endoplasmic reticulum and in the Golgi apparatus followed by vesicular delivery to the plasma membrane, membrane turnover with final catabolism in lysosomes, and shedding of me...

abstract：:Plants have evolved to cope with fluctuations in water supply by gating their water channels known as aquaporins. During flooding, a rapid drop of cytosolic pH due to anoxia leads to a simultaneous closure of the aquaporins in the plasma membrane. The closing mechanism has been suggested to involve a conserved histidi...
