Summary: Enables eukaryotic initiation factor 4E binding activity. Involved in several processes, including negative regulation of cell size; regulation of translation; and transmembrane receptor protein tyrosine kinase signaling pathway. Located in cytosol. Is expressed in several structures, including digestive system; ectoderm anlage; extended germ band embryo; germ layer; and gonad. Human ortholog(s) of this gene implicated in lung non-small cell carcinoma. Orthologous to human EIF4EBP1 (eukaryotic translation initiation factor 4E binding protein 1); EIF4EBP2 (eukaryotic translation initiation factor 4E binding protein 2); and EIF4EBP3 (eukaryotic translation initiation factor 4E binding protein 3).

4E-BP determines lifespan in the context of temperature changes, revealing a genetic mechanism for cold-induced longevity in this model organism. Our results suggest that the 4E-BP pathway, chiefly thought of as a nutrient sensor, may represent a master metabolic switch responding to diverse environmental factors
Title: The 4E-BP growth pathway regulates the effect of ambient temperature on Drosophila metabolism and lifespan.
Here, the authors show that cell autonomous insulin signaling within the Drosophila CM9 motor neuron regulates the release of neurotransmitter via alteration of the synaptic vesicle fusion machinery. This effect of insulin utilizes the FOXO-dependent regulation of the thor gene, which encodes the Drosophila homologue of the eif-4e binding protein (4eBP).
