Translational control by influenza virus: suppression of the kinase that phosphorylates the alpha subunit of initiation factor eIF-2 and selective translation of influenza viral mRNAs. [PDF]

Molecular and Cellular Biology, 1986
Selective translation of influenza viral mRNAs occurs after influenza virus superinfection of cells infected with the VAI RNA-negative adenovirus mutant dl331 (M. G. Katze, Y.-T. Chen, and R. M. Krug, Cell 37:483-490, 1984). Cell extracts from these doubly infected cells catalyze the initiation of essentially only influenza viral protein synthesis ...

Rapid CO2 effects on protein‐related metabolism during photosynthetic gas exchange

The Plant Journal, Volume 127, Issue 1, July 2026.
SUMMARY It is common practice to vary atmospheric CO2 mole fraction (Ca) during gas exchange experiments to manipulate photorespiration and explore photosynthetic properties such as maximum carboxylation velocity. In doing so, it is assumed that changing Ca essentially alters the carboxylation‐to‐oxygenation ratio, with negligible effects on other ...

N6‐Methyladenosine (m6A) in Liver Disease: Pathogenic Mechanisms and Therapeutic Potential

iNew Medicine, Volume 2, Issue 2, June 2026.
ABSTRACT Accumulating evidence highlights the critical role of epigenetic modifications, particularly N6‐methyladenosine (m6A), in liver disease. As the most abundant RNA modification in eukaryotic cells, m6A is dynamically regulated by multicomponent m6A methyltransferases (e.g., METTL3 and METTL14), demethylases (FTO and ALKBH5), and m6A‐binding ...

Gallic Acid‐Responsive microRNAs Reprogram Lignification During Drought Acclimation Process in Spearmint

Plant Biotechnology Journal, Volume 24, Issue 6, Page 4263-4281, June 2026.
ABSTRACT Mentha spicata L. (spearmint) is a high‐value aromatic and medicinal species, whose productivity is strongly affected by water deficit. Nevertheless, the molecular mechanisms underlying drought acclimation in this mint remain largely unexplored. Thus, here, we investigated the microRNA‐mediated regulatory processes triggered in M.

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

Journal 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.

Hsp90 mediates activation of the heme regulated eIF-2 alpha kinase during oxidative stress.

Indian journal of biochemistry & biophysics, 2010
The heme-regulated inhibitor (HRI), a member of the eIF-2 alpha kinase family is crucial for regulating protein synthesis during stress. In addition to heme, stress proteins Hsp90 and Hsp70 are known to regulate HRI. The present study aims to determine the physical association of these Hsps in the regulation of HRI activation during oxidative stress ...

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

Journal 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).

Regulation of protein synthesis in rabbit reticulocyte lysates [PDF]

FEBS Letters, 1986
The heme‐regulated protein kinase, which specifically phosphorylates the 38‐kDa subunit of initiation factor eiF‐2, can utilize adenosine 5′‐O‐(3‐thiotriphosphate) (ATP[γS]) as a substrate. The rate of thiophosphorylation is 5‐6‐times slower than that observed with ATP.
