Specificity
Detects endogenous levels of 4E-BP1 only when dephosphorylated at Thr46. This antibody cross-reacts with 4E-BP2 and 4E-BP3 dephosphorylated at equivalent sites. Phospho- 4E-BP1 (Ser65) Antibody detects endogenous levels of 4EBP1 when phosphorylated at Ser65, and may also recognize 4E-BP1 when phosphorylated at Ser101. Phospho-4E-BP1 (Ser65) (174A9) Rabbit mAb detects endogenous levels of 4E-BP1 when phosphorylated at Ser65. Phospho-4E-BP1 (Thr70) Antibody detects endogenous levels of 4E-BP1 only when phosphorylated at Thr70. 4E-BP1 (53H11) Rabbit mAb detects endogenous levels of total 4E-BP1 protein. 4E-BP2 Antibody detects endogenous levels of total 4E-BP2 independent of phosphorylation and does not cross-react significantly with 4E-BP1.

Immunogen
Synthetic phosphopeptide (KLH-coupled) corresponding to residues surrounding Thr37 and Thr46 of mouse 4E-BP1, residues surrounding Thr46 of human 4E-BP1, residues surrounding Ser65 of mouse 4E-BP1 and derived from the sequence around Ser112 of human 4E-BP1.
Preparation and Storage
May be stored at 4 degree C for short-term only. For long-term storage, aliquot and store at -20 degree C. Aliquots are stable for at least 12 months at -20 degree 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.
Other Notes
Small volumes of anti-EIF4EBP1 antibody vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.
Related Product Information for
anti-EIF4EBP1 antibody
PHAS-I, also known as eIF4E-BP1 and PHAS-II,-III (eIF4E-BP2, 3), are members of a family of proteins that regulate eukaryotic translation initiation which is mediated by the cap structure (m7GpppN, where N=any nucleotide) present at the 5í end of all cellular mRNAs, except organellar (1). The m7 cap is essential for the translation of most mRNA because it directs the translation machinery of the 5í end of the mRNA via its interaction with the cap binding protein, the translation initiation factor 4E(eIF4E) (2). eIF4E plays an principal role in determining global translation rates because its interaction with the cap facilitates the binding of the ribosome to the mRNA. Consistent with this role, eIF4E is required for cell cycle progression, exhibits anti-apoptotic activity and when overexpressed transforms cells (2). Interaction with PHAS proteins prevents incorporation of eIF4E into an active translation initiation complex and inhibits cap-dependent translation. However, this inhibitory effect is alleviated following phosphorylation of the PHAS proteins by a P13K-dependent pathway, involving signaling by the anti-apoptotic kinase Akt/PKB, as well as FRAP/mTOR (2). Rat PHAS-I has 117 amino acids with a apparent molecular weight of 22kD and is 93% identical to eIF-4E-BPI cloned from human placenta (3, 4). PHAS-I and ñII were found to have overlapping but different patterns of expression in tissues. PHAS-I is expressed in a wide variety of cell types with the highest being in two of the most insulin-responsive tissues, adipocytes and skeletal muscle (3). Both PHAS proteins are phosphorylated in response to insulin or growth factors such as EGF, PDGF and IGF-1. Increasing cAMP in cells promotes dephosphorylation of both PHAS-I and PHAS-II but that regulation of the two protein differ because PHAS-II, unlike PHAS-I is readily phosphorylated by PKA (5). The PHAS-I initiation factor has 2-8 phosphorylation sites and is multiply phosphorylated by insulin-stimulated protein kinase(s) resulting in 8-10 phosphorylated isoforms in exponentially growing cells. Changes occur in the expression of these isoforms in response to stresses such as heat shock, and this may contribute to translation repression (6).

NCBI Summary for EIF4EBP1
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.

UniProt Comments for EIF4EBP1
4E-BP1: binds to eIF4E, preventing its assembly into the EIF4F complex and inhibiting cap-dependent translation. Phosphorylation of 4E-BP1 disrupts this binding, activating cap-dependent translation. Mediates the regulation of protein translation by hormones, growth factors and other stimuli that signal through the PI3 kinase pathway.
