Eif2s1 Gene Summary [Rat]
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).

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Eif2s1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
