Summary: Enables guanyl-nucleotide exchange factor activity and translation initiation factor activity. Involved in regulation of translational initiation. Located in cytosol. Part of eukaryotic translation initiation factor 2B complex and guanyl-nucleotide exchange factor complex. Used to study leukoencephalopathy with vanishing white matter. 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]

What's a GeneRIF?

These data show that multiple contacts between eIF2gamma and eIF2Bepsilon mediate nucleotide exchange.
Title: Critical contacts between the eukaryotic initiation factor 2B (eIF2B) catalytic domain and both eIF2beta and -2gamma mediate guanine nucleotide exchange.
