Regulation of protein kinase B/Akt-serine 473 phosphorylation by integrin-linked kinase: critical roles for kinase activity and amino acids arginine 211 and serine 343.
Protein kinase B (PKB/Akt) is a regulator of cell survival and apoptosis. To become fully activated, PKB/Akt requires phosphorylation at two sites, threonine 308 and serine 473, in a phosphatidylinositol (PI) 3-kinase-dependent manner. The kinase responsible for phosphorylation of threonine 308 is the PI 3-kinase-dependent kinase-1 (PDK-1), whereas phosphorylation of serine 473 has been suggest...
متن کاملSpecific dephosphorylation of phosphoproteins by protein-serine and -tyrosine kinases.
Five protein kinases are shown to serve as specific phosphatases in the absence of ADP. Although the rates of hydrolysis are very slow compared to the forward phosphorylation rates under optimal conditions, they are of the same order as the reverse reaction in the presence of ADP. Because cells contain approximately equal to 3 mM ATP, neither the reverse reaction nor the phosphatase is likely t...
متن کاملCeramide kinase uses ceramide provided by ceramide transport protein: localization to organelles of eicosanoid synthesis.
Ceramide kinase (CERK) is a critical mediator of eicosanoid synthesis, and its product, ceramide-1-phosphate (C1P), is required for the production of prostaglandins in response to several inflammatory agonists. In this study, mass spectrometry analysis disclosed that the main forms of C1P in cells were C(16:0) C1P and C(18:0) C1P, suggesting that CERK uses ceramide transported to the trans-Golg...
متن کاملProtein kinase A inhibits leukotriene synthesis by phosphorylation of 5-lipoxygenase on serine 523.
Leukotrienes (LTs) are lipid messengers generated by leukocytes that drive inflammation and modulate neighboring cell function. The synthesis of LTs from arachidonic acid is initiated by the enzyme 5-lipoxygenase (5-LO). We report for the first time that LT synthesis is inhibited by the direct action of protein kinase A (PKA) on 5-LO. The catalytic subunit of PKA directly phosphorylated 5-LO in...
متن کاملDysregulation of human bestrophin-1 by ceramide-induced dephosphorylation.
Best vitelliform macular dystrophy is an inherited autosomal dominant, juvenile onset form of macular degeneration caused by mutations in a chloride ion channel, human bestrophin-1 (hBest1). Mutations in Best1 have also been linked to several other forms of retinopathy. In addition to mutations, hBest1 dysfunction might come about by disruption of other processes that regulate Best1 function. H...
