Summary
Enables translation initiation factor activity. Predicted to be involved in translational initiation. Predicted to be located in cytosol. Predicted to be part of eukaryotic 48S preinitiation complex; eukaryotic translation initiation factor 2 complex; and eukaryotic translation initiation factor 2B complex. Is expressed in adult head; adult heart; and ovary. Human ortholog(s) of this gene implicated in Alzheimer's disease. Orthologous to human EIF2S1 (eukaryotic translation initiation factor 2 subunit alpha). [provided by Alliance of Genome Resources, Nov 2024]
