A picture says more than a thousand words: Structural insights into hepatitis C virus translation initiation
Pantxika Bellecave, Darius Moradpour – 28 November 2006 – Protein synthesis in mammalian cells requires initiation factor eIF3, a ∼750‐kilodalton complex that controls assembly of 40S ribosomal subunits on messenger RNAs (mRNAs) bearing either a 5′‐cap or an internal ribosome entry site (IRES). Cryoelectron microscopy reconstructions show that eIF3, a five‐lobed particle, interacts with the hepatitis C virus (HCV) IRES RNA and the 5′‐cap binding complex eIF4F via the same domain.
