This antibody may cross-react with 4E-BP2 and 4E-BP3 when phosphorylated at equivalent sites. Non-specific staining has been observed in mitotic cells by immunofluorescence.\nSpecies Reactivity: Human, Mouse, Rat, Monkey, D. melanogaster\n\u003cb\u003eSource \/ Purification\u003c\/b\u003e\nMonoclonal antibody is produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Thr37 and Thr46 of mouse 4E-BP1.\n\u003cb\u003eBackground\u003c\/b\u003e\nTranslation 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 (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).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\n4E-BP1; 4EBP1; BP-1; eIF4E-binding protein 1; EIF4EBP1; eukaryotic translation initiation factor 4E binding protein 1; Eukaryotic translation initiation factor 4E-binding protein 1; MGC4316; PHAS-I; Phosphorylated heat- and acid-stable protein regulated by insulin 1\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H M R Mk Dm\nSENSITIVITY: Endogenous\nMW (kDa): 15 to 20\nSource\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46798055080105,"sku":"2855S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-2855s","provider":"Iright","version":"1.0","type":"link"}
