Summary
Enables guanyl-nucleotide exchange factor activity. Predicted to be involved in translational initiation. Predicted to be located in cytosol. Predicted to be part of eukaryotic translation initiation factor 2B complex. Is expressed in adult head. Human ortholog(s) of this gene implicated in leukoencephalopathy with vanishing white matter and leukoencephalopathy with vanishing white matter 5. Orthologous to human EIF2B5 (eukaryotic translation initiation factor 2B subunit epsilon). [provided by Alliance of Genome Resources, Dec 2024]
