Anti-4EBP1 Antibody (Mouse Monoclonal antibody) General Information
Reacts with: Human
Recombinant Human 4E-BP1 / EIF4EBP1 Protein (Catalog#10022-H07E)
This antibody was produced from a hybridoma resulting from the fusion of a mouse myeloma with B cells obtained from a mouse immunized with purified, recombinant Human 4E-BP1 / EIF4EBP1 (rh 4E-BP1 / EIF4EBP1; Catalog#10022-H07E; NP_004086.1; Ser2-Ile118). The IgG fraction of the cell culture supernatant was purified by Protein A affinity chromatography.

Flow cytometric analysis of Human 4EBP1 expression on HeLa cells. The cells were treated according to manufacturer’s manual (BD Pharmingen™ Cat. No. 554714), stained with purified anti-Human 4EBP1, then a FITC-conjugated second step antibody. The fluorescence histograms were derived from gated events with the forward and side light-scatter characteristics of intact cells.

4EBP1 Background Information
The translational suppressor eIF4E binding protein-1, 4E-BP1 functions as a key regulator in cellular growth, differentiation, apoptosis and survival. The Eif4ebp1 gene, encoding 4E-BP1, is a direct target of a transcription factor activating transcription factor-4 (ATF4), a master regulator of gene expression in stress responses. 4E-BP1 is characterized by its capacity to bind specifically to eIF4E and inhibit its interaction with eIF4G. Phosphorylation of 4E-BP1 regulates eIF4E availability, and therefore, cap-dependent translation, in cell stress. Binding of eIF4E to eIF4G is inhibited in a competitive manner by 4E-BP1. Phosphorylation of 4E-BP1 decreases the affinity of this protein for eIF4E, thus favouring the binding of eIF4G and enhancing translation. 4E-BP1 is important for beta-cell survival under endoplasmic reticulum (ER) stress. 4E-BP1 mediates the regulation of protein translation by hormones, growth factors and other stimuli that signal through the MAP kinase and mTORC1 pathways. Recently, 4E-BP1 was found to be a key factor, which converges several oncogenic signals, phosphorylates the molecules, and drives the downstream proliferative signals. Recent studies showed that high expression of phosphorylated 4E-BP-1 (p-4E-BP1) is associated with poor prognosis, tumor progression, or nodal metastasis in different human cancers.
