Disulfide Bond Formation in the Regulation of eIF-2 α Kinase by Heme [PDF]

open access: hybridJournal of Biological Chemistry, 1989
The inhibition of the autophosphorylation of the heme-regulated eukaryotic initiation factor (eIF)-2 alpha kinase (HRI) by hemin is very similar to that produced by thiol oxidation by diamide. The results obtained from the analysis of sodium dodecyl sulfate-polyacrylamide gel electrophoresis of unphosphorylated and phosphorylated HRI under reducing and

Effects of glucose 6-phosphate and hemin on activation of heme-regulated eIF-2 alpha kinase in gel-filtered reticulocyte lysates.

open access: hybridJournal of Biological Chemistry, 1984
In heme-deficient reticulocyte lysates, protein synthesis initiation is inhibited due to the activation of a heme-regulated protein kinase which blocks protein synthesis by the specific phosphorylation of the alpha-sub-unit of eukaryotic initiation factor 2 (eIF-2 alpha).

Kinetics of Phosphorylation of eIF-2 by the hemin-controlled repressor and casein kinase II. Inhibition by hemin and 2,3-diphosphoglyceric acid.

open access: hybridJournal of Biological Chemistry, 1982
The kinetics of phosphorylation of eukaryotic initiation factor 2 (eIF-2) by two cyclic nucleotide-independent protein kinases from rabbit reticulocytes have been studied. The hemin-controlled repressor (HCR) and casein kinase II phosphorylate the alpha and beta subunits of eIF-2, respectively.

The Effects of Glyburide on Apoptosis and Endoplasmic Reticulum Stress in INS-1 Cells in a Glucolipotoxic Condition [PDF]

open access: yesDiabetes & Metabolism Journal, 2011
Backgroundβ-cell death due to endoplasmic reticulum (ER) stress has been regarded as an important pathogenic component of type 2 diabetes. The possibility has been suggested that sulfonylurea, currently being used as one of the main oral hypoglycemic ...

Purification and characterization of eukaryotic initiation factor (eIF)-2 alpha kinases from Ehrlich ascites tumor cells

open access: hybridJournal of Biological Chemistry, 1993
A major mechanism of regulation of mammalian protein synthesis initiation is accomplished by the phosphorylation of the alpha subunit of eukaryotic initiation factor (eIF) 2. This modification inhibits the activity of another initiation factor, guanine nucleotide exchange factor, preventing conversion of eIF-2.GDP to eIF-2.GTP and hence binding of ...

Gefitinib and Erlotinib Lead to Phosphorylation of Eukaryotic Initiation Factor 2 Alpha Independent of Epidermal Growth Factor Receptor in A549 Cells. [PDF]

open access: yesPLoS ONE, 2015
Gefitinib and erlotinib are anticancer agents, which inhibit epidermal growth factor receptor (EGFR) tyrosine kinase. Interstitial lung disease (ILD) occurs in patients with non-small cell lung cancer receiving EGFR inhibitors.
