Opis ogólny
The eukaryotic translation initiation factor 2 subunit α (EIF2A) gene is mapped to human chromosome 14q23.3. The eukaryotic translation initiation factor 2 (eIF2), a multimeric protein is composed of three subunits termed α, β, and γ.
Specyficzność

Działania biochem./fizjol.
Increased eIF2α phosphorylation has been observed in Alzheimer′s disease. Viral infections are also known to induce eIF2α phosphorylation.
The main role of eIF2 complex is to transfer Met-tRNAi in the presence of GTP to the 40S ribosomal subunit during the initiation of translation. Regulation of the initiation of translation at the level of eIF2 involves the phosphorylation of eIF2α at a conserved Ser51 residue. This leads to inhibition of eIF2β activity, thus reducing guanine nucleotide exchange and consequently, the translation rate. Protein synthesis inhibition at the level of eIF2α phosphorylation is linked to a variety of cell stress signaling pathways via specific kinases. Phosphorylation of eIF2α reduces the rate of translation and gives the cell time to correct the stress damage, and selectively enhance the translation of genes important for stress remedy.
Postać fizyczna
Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.
Przechowywanie i stabilność
For continuous use, store at 2–8 °C for up to one month. For extended storage, freeze in working aliquots. Repeated freezing and thawing, or storage in “frost-free” freezers, is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use. Working dilutions should be discarded if not used within 12 hours.

In response to environmental stresses, a family of protein kinases phosphorylate eIF2 (eukaryotic initiation factor 2) to alleviate cellular injury or alternatively induce apoptosis. Phosphorylation of eIF2 reduces global translation, allowing cells to conserve resources and to initiate a reconfiguration

Phosphorylation of eukaryotic initiation factor-2 (eIF-2) is an important mechanism regulating general translation initiation. Two mammalian eIF-2 kinases, the double-stranded-RNA-dependent kinase (PKR) and heme-regulated inhibitor kinase (HRI), have been characterized by sequencing, revealing shared sequence and structural features distinct from

Eukaryotic initiation factor eIF2 and its 'exchange factor' eIF2B play a key role in the regulation of protein synthesis in eukaryotes from yeast to mammals. Phosphorylation of eIF2 inhibits eIF2B and thus translation initiation. Four eIF2 kinases are now known

Eukaryotic gene expression is a complicated process primarily regulated at the levels of gene transcription and mRNA translation. The latter involves four main steps: initiation, elongation, termination and recycling. Translation regulation is primarily achieved during initiation which is orchestrated by

Initiation of protein synthesis in eukaryotes is a complex process requiring more than 12 different initiation factors, comprising over 30 polypeptide chains. The functions of many of these factors have been established in great detail; however, the precise role of
