Description
CST's PathScan® Total 4E-BP1 Sandwich ELISA Kit is a solid phase sandwich enzyme-linked immunosorbent assay (ELISA) that detects endogenous levels of 4E-BP1. A 4E-BP1 Rabbit Antibody has been coated onto the microwells. After incubation with cell lysates, 4E-BP1 (phospho and nonphospho) is captured by the coated antibody. Following extensive washing, a 4E-BP1 Mouse Detection Antibody is added to detect the captured 4E-BP1 protein. Anti-mouse IgG, HRP-linked Antibody #7076 is then used to recognize the bound detection antibody. HRP substrate, TMB, is added to develop color. The magnitude of absorbance for this developed color is proportional to the quantity of total 4E-BP1.
*Antibodies in kit are custom formulations specific to kit.
Specificity/Sensitivity
This kit detects proteins from the indicated species, as determined through in-house testing, but may also detect homologous proteins from other species.
Background
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).
