Summary: Predicted to enable ribosome binding activity and translation initiation factor activity. Involved in several processes, including cellular response to amino acid starvation; negative regulation of translational initiation in response to stress; and stress granule assembly. Acts upstream of or within protein autophosphorylation; regulation of translational initiation in response to stress; and translation. Located in cytoplasmic stress granule and nucleus. Is active in synapse. Is expressed in several structures, including brain ventricular layer; jaw; nose; orbito-sphenoid; and thymus primordium. Human ortholog(s) of this gene implicated in Alzheimer's disease. Orthologous to human EIF2S1 (eukaryotic translation initiation factor 2 subunit alpha).

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.
