Application Abreviews Notes
IHC-P Use at an assay dependent concentration.
WB Use at an assay dependent concentration. Detects a band of approximately 15-20 kDa (predicted molecular weight: 12 kDa).
Flow Cyt Use at an assay dependent concentration.
IP Use at an assay dependent concentration.
  • Application notes
    Is unsuitable for ICC.
  • Target

    • 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.
    • Sequence similarities

      Belongs to the eIF4E-binding protein family.
    • Post-translational

      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.
