Summary: Enables eukaryotic initiation factor 4E binding activity. Involved in several processes, including cell surface receptor protein tyrosine kinase signaling pathway; determination of adult lifespan; and regulation of translation. Located in cytosol. Is active in glutamatergic synapse and neuromuscular junction. Is expressed in several structures, including anlage in statu nascendi; extraembryonic structure; gut section; head epidermis primordium; and salivary gland. Orthologous to several human genes including EIF4EBP1 (eukaryotic translation initiation factor 4E binding protein 1) and EIF4EBP2 (eukaryotic translation initiation factor 4E binding protein 2).

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).
