4E-BP1 Blocking Peptide #1053
Gallery: 4E-BP1 Blocking Peptide #1053
This peptide is used to block 4E-BP1 (53H11) Rabbit mAb #9644 reactivity in western blot and dot blot protocols.
The quality of the peptide was evaluated by reversed-phase HPLC and by mass spectrometry. The peptide blocks 4E-BP1 (53H11) Rabbit mAb #9644 signal in dot blot.
Use as a blocking reagent to evaluate the specificity of antibody reactivity in dot blot protocols.Storage: Supplied in 20 mM potassium phosphate (pH 7.0), 50 mM NaCl, 0.1 mM EDTA, 1 mg/ml BSA and 5% glycerol. 1% DMSO. Store at –20°C.
Translation repressor protein 4E-BP1 (also known as PHAS-1) inhibits cap-dependent translation by binding to the translation initiation factor eIF4E. 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 at 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).
