Summary
Predicted to enable translation initiation factor activity. Predicted to be involved in cytoplasmic translational initiation. Predicted to be located in cytosol. Predicted to be part of eukaryotic translation initiation factor 2B complex. Is expressed in several structures, including adult head; embryonic epipharynx; embryonic/larval midgut primordium; gland; and gut section. Human ortholog(s) of this gene implicated in leukoencephalopathy with vanishing white matter 4. Orthologous to human EIF2B4 (eukaryotic translation initiation factor 2B subunit delta).
