eukaryotic translation initiation factor 4E binding protein<br />1
Phosphorylated heat- and acid-stable protein regulated by insulin 1
eIF4E-binding protein 1
Background Information
4E-BP1 is a eukaryotic translation initiation factor (eIF4E- binding protein), also known as PHAS-1. The binding of 4E-BP to eIF4E is regulated by phosphorylation and is reversible. Non-phosphorylated 4E-BP1 bind strongly to eIF4E; however, phosphorylated 4E-BP1 will not bind to eIF4E. Akt, TOR, MAP, S6, and Cdc2 kinases are able to inactivate 4E-BP1 by phosphorylation. 4E-BP1 undergoes phosphorylation which releases it from eIF4E, ultimately forming initiation complexes that aid in the upregulation of protein synthesis.

Specificity
This antibody detects 4E-BP1 phosphorylated at Ser65.
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.
FUNCTION:Regulates eIF4E activity by preventing its assembly into the eIF4F complex. Mediates the regulation of protein translation by hormones, growth factors and other stimuli that signal through the MAP kinase and mTORC1 pathways. SUBUNIT STUCTURE:Nonphosphorylated EIF4EBP1 competes with EIF4G1/EIF4G3 to interact with EIF4E; insulin stimulated MAP-kinase (MAPK1 and MAPK3) or mTORC1 phosphorylation of EIF4EBP1 causes dissociation of the complex allowing EIF4G1/EIF4G3 to bind and consequent initiation of translation. Interacts with RPTOR. PTM:Phosphorylated on serine and threonine residues in response to insulin, EGF and PDGF. Phosphorylation at Thr-37, Thr-46, Ser-65 and Thr-70 is regulated by mTORC1. Phosphorylated upon DNA damage, probably by ATM or ATR. SEQUENCE SIMILARITIES:Belongs to the eIF4E-binding protein family.

Usage Statement
Unless otherwise stated in our catalog or other company documentation accompanying the product(s), our products are intended for research use only and are not to be used for any other purpose, which includes but is not limited to, unauthorized commercial uses, in vitro diagnostic uses, ex vivo or in vivo therapeutic uses or any type of consumption or application to humans or animals.
Storage and Shipping Information
Storage Conditions
Stable for 1 year at -20ºC from date of receipt.
Handling Recommendations: Upon first thaw, and prior to removing the cap, centrifuge the vial and gently mix the solution. Aliquot into microcentrifuge tubes and store at -20°C. Avoid repeated freeze/thaw cycles, which may damage IgG and affect product performance.
