4E-BP1 (also known as PHAS-1) normally binds eIF4E, inhibiting cap-dependent translation.
Hyperphosphorylation of 4E-BP1 disrupts this binding, activating cap-dependent translation (1).
The PI3 kinase/Akt pathway and FRAP/mTOR kinase regulate 4E-BP1 (2,3).
4E-BP1 is phosphorylated in vivo on multiple residues (4); phosphorylation by FRAP/mTOR on Thr37 and Thr46 of human 4E-BP1 may prime it for subsequent phosphorylation at sites including Ser65 and Thr70 (5).
Applications:Suitable for use in Western Blot.
Other applications not tested.
Recommended Dilution:Western Blot: 1:1000Optimal dilutions to be determined by the researcher.
Storage and Stability:May be stored at 4°C for short-term only.
For long-term storage, store at -20°C.
Aliquots are stable for at least 12 months at -20°C.
For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
Further dilutions can be made in assay buffer.
