Applications
Western Blot
Western blot analysis of K562 cell extract untreated or treated with imatinib using Phospho-4E-BP1 (Thr37/Thr46) antibody 4EB1T37T46-A5 at 1 ng/mL.Immunohistochemistry
Immunohistochemical staining of rat kidney cells including peptide blocking shows phospho-specificity for 4EB1T37T46-A5 Cat. #2041. Anti-rabbit secondary antibody staining (red) is punctate in the nuclei. Neither control peptide (A) nor non-phospho 4E-BP1 peptide (B) blocks 4EB1T37T46-A5 staining but phospho 4E-BP1 (T37/T46) peptide efficiently blocks signal (C). No signal was observed when the primary antibody is omitted (D). The central object in the field is a glomerulus with surrounding tubules sectioned in various orientations.Flow Cytometry
Peptide blocking flow cytometric analysis of Jurkat cells LY294002 plus wortmannin plus U0126 LWU) treated cells stained with secondary antibody as negative control (light blue) or treated with LWU (red) or treated with FBS (green) or LUW and blocked with phospho-peptide (black) or FBS and blocked with phospho peptide (gold) or LUW and blocked with non-phospho peptide (dark blue) or FBS and blocked with non-phospho peptide (purple) using Phospho-4E-BP1 (Thr37/Thr46) antibody 4EB1T37T46-A5 at 0.1 ug/mL. -

HyperlinkGene Summary
This gene encodes one member of a family of translation repressor proteins. The protein directly interacts with eukaryotic translation initiation factor 4E (eIF4E), which is a limiting component of the multisubunit complex that recruits 40S ribosomal subunits to the 5' end of mRNAs. Interaction of this protein with eIF4E inhibits complex assembly and represses translation. This protein is phosphorylated in response to various signals including UV irradiation and insulin signaling, resulting in its dissociation from eIF4E and activation of mRNA translation.
