Purified polyclonal antibody supplied in PBS with 0.09% (W/V) sodium azide. This antibody is purified through a protein A column, followed by peptide affinity purification.
concentration :
Vial Concentration: 0.29
storage stability :
Maintain refrigerated at 2-8 degree C for up to 6 months. For long term storage store at -20 degree C in small aliquots to prevent freeze-thaw cycles.
tested application :
Dot Blot (DB), ELISA (EIA)
other info1 :
Antigen Type: Synthetic Peptide
other info2 :
Antigen Source: HUMAN. Function : Regulates eIF4E activity by preventing its assembly into the eIF4F complex:. hypophosphorylated form competes with EIF4G1/EIF4G3 and strongly binds to EIF4E, leading to repress translation. Mediates the regulation of protein translation by hormones, growth factors and other stimuli that signal through the MAP kinase and mTORC1 pathways.

products description :
EIF4EBP1 is a member of a family of translation repressor proteins. This 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 EIF4EBP1 with eIF4E inhibits complex assembly and represses translation. EIF4EBP1 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 summary :
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. Protein type: Translation initiation; Translation. Chromosomal Location of Human Ortholog: 8p12. Cellular Component: nucleoplasm; protein complex; cytoplasm; cytosol. Molecular Function: protein binding; translation repressor activity; eukaryotic initiation factor 4E binding. Biological Process: negative regulation of translational initiation; cellular protein metabolic process; response to ethanol; TOR signaling pathway; translation; insulin receptor signaling pathway; translational initiation; gene expression; positive regulation of mitotic cell cycle; negative regulation of protein complex assembly; lung development; G1/S transition of mitotic cell cycle
