Summary: Predicted to enable ribosome binding activity and translation initiation factor activity. Involved in several processes, including negative regulation of guanyl-nucleotide exchange factor activity; positive regulation of type B pancreatic cell apoptotic process; and response to manganese-induced endoplasmic reticulum stress. Located in glial limiting end-foot. Part of eukaryotic translation initiation factor 2 complex and translation initiation ternary complex. Used to study middle cerebral artery infarction. Biomarker of transient cerebral ischemia. Human ortholog(s) of this gene implicated in Alzheimer's disease. Orthologous to human EIF2S1 (eukaryotic translation initiation factor 2 subunit alpha).

C9orf72 regulates the unfolded protein response and stress granule formation by interacting with eIF2alpha.
Title: C9orf72 regulates the unfolded protein response and stress granule formation by interacting with eIF2α.
TorsinA was post-transcriptionally upregulated upon acute ER stress, suggesting a role in this response. Increased basal phosphorylation of eIF2alpha in DYT1 transgenic rats was associated with abnormal response to acute ER stress. Unbiased RNA-Seq-based transcriptomic analysis of embryonic brain tissue in heterozygous and homozygous DYT1 knockin mice confirmed presence of eIF2alpha dysregulation in the DYT1 brain.

results demonstrate the sensitivity of eukaryotic initiation factor 2alpha-subunit (eIF2alpha) to stimulant exposure. Amphetamine possesses the ability to stimulate eIF2alpha phosphorylation in striatal and medial prefrontal cortex neurons in vivo in a dopamine D1 and D2 receptor-dependent manner.
Title: Amphetamine elevates phosphorylation of eukaryotic initiation factor 2α (eIF2α) in the rat forebrain via activating dopamine D1 and D2 receptors.
These results suggest a critical role of the mTOR/eIF2alpha pathway in hypoxic vascular remodeling and pulmonary arterial vascular smooth muscle cell proliferation of pulmonary hypertension.

Data suggest maternal overweight due to high-fat diet up-regulates mTOR complex 1 (mechanistic target of rapamycin) activity and down-regulates eIF2 alpha subunit phosphorylation in placenta; such alterations contribute to placental/fetal overgrowth.
Title: Maternal overweight induced by a diet with high content of saturated fat activates placental mTOR and eIF2alpha signaling and increases fetal growth in rats.
eIF2a is hyperphosphorylated in the cortex of aged rats.
Title: ApoE ε4 is associated with eIF2α phosphorylation and impaired learning in young mice.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
