4E-BP1 Antibody detects endogenous levels of total 4E-BP1, independent of phosphorylation.
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Ser112 of human 4E-BP1. Antibodies are purified by protein A affinity chromatography.
BackgroundTranslation repressor protein 4E-BP1 (also known as PHAS-1) inhibits cap-dependent translation by binding to the eIF4E translation initiation factor. Hyperphosphorylation of 4E-BP1 disrupts this interaction and results in activation of cap-dependent translation (1). Both the PI3 kinase/Akt pathway and FRAP/mTOR kinase regulate 4E-BP1 activity (2,3). Multiple 4E-BP1 residues are phosphorylated in vivo (4). While phosphorylation by FRAP/mTOR on Thr37 and Thr46 does not prevent the binding of 4E-BP1 to eIF4E, it is thought to prime 4E-BP1 for subsequent phosphorylation at Ser65 and Thr70 (5).
