  • Function

    Component of the protein complex eIF4F, which is involved in the recognition of the mRNA cap, ATP-dependent unwinding of 5'-terminal secondary structure and recruitment of mRNA to the ribosome.
  • Involvement in disease

    Defects in EIF4G1 are the cause of Parkinson disease type 18 (PARK18) [MIM:614251]. An autosomal dominant, late-onset form of Parkinson disease. Parkinson disease is a complex neurodegenerative disorder characterized by bradykinesia, resting tremor, muscular rigidity and postural instability, as well as by a clinically significant response to treatment with levodopa. The pathology involves the loss of dopaminergic neurons in the substantia nigra and the presence of Lewy bodies (intraneuronal accumulations of aggregated proteins), in surviving neurons in various areas of the brain.
  • Sequence similarities

    Belongs to the eIF4G family.
    Contains 1 MI domain.
    Contains 1 MIF4G domain.
    Contains 1 W2 domain.
  • Post-translational

    Phosphorylated at multiple sites in vivo. Phosphorylation at Ser-1185 by PRKCA induces binding to MKNK1.
    Following infection by certain enteroviruses, rhinoviruses and aphthoviruses, EIF4G1 is cleaved by the viral protease 2A, or the leader protease in the case of aphthoviruses. This shuts down the capped cellular mRNA transcription.

  • Anti-eIF4G1 antibody (ab47649) at 1 µg/ml + HEK293 Human embryonic kidney cell line Whole Cell Lysate at 10 µg

    IRDye 680 Conjugated Goat Anti-Rabbit IgG (H+L) at 1/10000 dilution

    Performed under reducing conditions.

    Predicted band size: 220 kDa
    Observed band size: 220 kDa
    Additional bands at: 110 kDa. We are unsure as to the identity of these extra bands.

  • ICC/IF image of ab47649 stained human HeLa cells. The cells were methanol fixed (5 min), permabilised in PBS-T (20 min) and incubated with the antibody (ab47649, 1µg/ml) for 1h at room temperature. 1%BSA / 10% normal goat serum / 0.3M glycine was used to quench autofluorescence and block non-specific protein-protein interactions. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red). DAPI was used to stain the cell nuclei (blue).
