Ceramides 32-40 AKT serine/threonine kinase 1 Homo sapiens 109-112 15220355-0 2004 Regulation of insulin action by ceramide: dual mechanisms linking ceramide accumulation to the inhibition of Akt/protein kinase B. Ceramides 66-74 AKT serine/threonine kinase 1 Homo sapiens 109-112 15220355-3 2004 Herein we utilized deletion constructs encoding two different functional domains of Akt/PKB to identify which region of the enzyme conferred responsiveness to ceramide. Ceramides 159-167 AKT serine/threonine kinase 1 Homo sapiens 84-91 15220355-4 2004 Surprisingly the findings obtained with these separate domains reveal that ceramide blocks insulin stimulation of Akt/PKB by two independent mechanisms. Ceramides 75-83 AKT serine/threonine kinase 1 Homo sapiens 114-117 15220355-4 2004 Surprisingly the findings obtained with these separate domains reveal that ceramide blocks insulin stimulation of Akt/PKB by two independent mechanisms. Ceramides 75-83 AKT serine/threonine kinase 1 Homo sapiens 118-121 15220355-5 2004 First, using the isolated pleckstrin homology domain, we found that ceramide specifically blocks the translocation of Akt/PKB, but not its upstream activator phosphoinositide-dependent kinase-1, to the plasma membrane. Ceramides 68-76 AKT serine/threonine kinase 1 Homo sapiens 118-125 15220355-6 2004 Second, using a construct lacking this pleckstrin homology domain, which does not require translocation for activation, we found that ceramide stimulates the dephosphorylation of Akt/PKB by protein phosphatase 2A. Ceramides 134-142 AKT serine/threonine kinase 1 Homo sapiens 179-182 15220355-6 2004 Second, using a construct lacking this pleckstrin homology domain, which does not require translocation for activation, we found that ceramide stimulates the dephosphorylation of Akt/PKB by protein phosphatase 2A. Ceramides 134-142 AKT serine/threonine kinase 1 Homo sapiens 183-186 15220355-8 2004 Moreover the results obtained provide a unifying theory to account for the numerous dissenting reports investigating the actions of ceramide toward Akt/PKB.
