| 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). | | | Catalog # | 0004-19 | | Applications | Suitable for use in Western Blotting. Other applications not tested. | | Recommended Dilution | Western Blot: 1:1000 | | Optimal 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. | | CAS Number | n/a | | Clone Type | Polyclonal | | Host | Rabbit | | Source | Mouse | | Form | Supplied as a liquid in 10mM sodium HEPES, pH 7.5, 150mM sodium chloride, BSA, 50% glycerol. | | Purity | Purified by protein A and peptide affinity chromatography. | | Immunogen | Synthetic phosphopeptide (KLH coupled) corresponding to residues surrounding Thr37 of mouse 4E-BP1 and Thr46 of mouse 4E-BP1. | | Specificity | Detects endogenous levels of 4E-BP1 only when phosphorylated at Thr37 and/or Thr46. This antibody may crossreact with 4E-BP2 and 4E-BP3 when phosphorylated at equivalent sites. | | | Important Note | This product as supplied is intended for research use only, not for use in human, therapeutic or diagnostic applications without the expressed written authorization of United States Biological. |
