EIF4EBP2 is a translation initiation repressor protein that plays a critical regulatory role in synaptic plasticity, learning, and memory. In the hypophosphorylated state, EIF4EBP2 competes with EIF4G1/EIF4G3, forms a complex with EIF4E, and inhibits translation. EIF4EBP2 Protein, Human (His) is the recombinant human-derived EIF4EBP2 protein, expressed by E. coli , with N-6*His labeled tag. The total length of EIF4EBP2 Protein, Human (His) is 120 a.a., with molecular weight of ~17.0 kDa.

EIF4EBP2, a repressor of translation initiation, plays a pivotal role in synaptic plasticity, learning, and memory formation. Acting as a key regulator of EIF4E activity, the hypophosphorylated form of EIF4EBP2 competes with EIF4G1/EIF4G3, forming a robust complex with EIF4E, thereby repressing translation. In contrast, the hyperphosphorylated form dissociates from EIF4E, enabling the interaction between EIF4G1/EIF4G3 and EIF4E, ultimately initiating translation. Enriched in the brain, EIF4EBP2 acts as a critical modulator of synapse activity and neuronal stem cell renewal, contributing to the regulation of protein translation in response to various signaling pathways, including MAP kinase and mTORC1. The intricate interplay between phosphorylation events and protein interactions underscores EIF4EBP2's multifaceted role in orchestrating cellular responses to external stimuli.
