Translational control of nociception via 4E-binding protein 1
Activation of the mechanistic/mammalian target of rapamycin (mTOR) kinase in models of acute and chronic pain is strongly implicated in mediating enhanced translation and hyperalgesia. However, the molecular mechanisms by which mTOR regulates nociception remain unclear. Here we show that deletion of the eukaryotic initiation factor 4E-binding protein 1 (4E-BP1), a major mTOR downstream effector...
متن کاملCell cycle-dependent phosphorylation of the translational repressor eIF-4E binding protein-1 (4E-BP1)
A fundamental control point in the regulation of the initiation of protein synthesis is the formation of the eukaryotic initiation factor 4F (eIF-4F) complex. The formation of this complex depends upon the availability of the mRNA cap binding protein, eIF-4E, which is sequestered away from the translational machinery by the tight association of eIF-4E binding proteins (4E-BPs). Phosphorylation ...
متن کاملTranslational homeostasis: eukaryotic translation initiation factor 4E control of 4E-binding protein 1 and p70 S6 kinase activities.
Eukaryotic translation initiation factor 4E (eIF4E) is the mRNA 5' cap binding protein, which plays an important role in the control of translation. The activity of eIF4E is regulated by a family of repressor proteins, the 4E-binding proteins (4E-BPs), whose binding to eIF4E is determined by their phosphorylation state. When hyperphosphorylated, 4E-BPs do not bind to eIF4E. Phosphorylation of t...
متن کاملTranslational control by neuroguidin, a eukaryotic initiation factor 4E and CPEB binding protein.
CPEB-mediated translation is important in early development and neuronal synaptic plasticity. Here, we describe a new eukaryotic initiation factor 4E (eIF4E) binding protein, Neuroguidin (Ngd), and its interaction with CPEB. In the mammalian nervous system, Ngd is detected as puncta in axons and dendrites and in growth cones and filopodia. Ngd contains three motifs that resemble those present i...
متن کاملExpression of eukaryotic initiation factor 4E and 4E binding protein 1 in colorectal carcinogenesis.
Cap dependent translation is mainly regulated at the level of the eukaryotic initiation factor 4E (eIF4E), the activity of which is controlled by phosphorylation and sequestration by its well established regulator, 4E binding protein 1 (4E-BP1). Both eIF4E and 4E-BP1 have been shown to be involved in the malignant progression of multiple human cancers, including colorectal cancer. However, the ...
