Predicted to enable GDP-dissociation inhibitor activity; eukaryotic initiation factor eIF2 binding activity; and translation initiation factor activity. Predicted to be involved in activation of GTPase activity; cytoplasmic translational initiation; and regulation of translational initiation. Predicted to act upstream of or within translation. Predicted to be located in cytoplasm and plasma membrane. Predicted to be active in cytosol. Is expressed in several structures, including central nervous system; dorsal root ganglion; ear; genitourinary system; and retina nuclear layer. Orthologous to human EIF5 (eukaryotic translation initiation factor 5). [provided by Alliance of Genome Resources, Apr 2022]
