    Yeast Ded1 promotes 48S translation pre-initiation complex assembly in an mRNA-specific and eIF4F-dependent manner

    Neha Gupta, Jon R Lorsch, Alan G Hinnebusch
    Yeast RNA helicase Ded1 stimulates ribosome recruitment of structure-laden native mRNAs in a reconstituted system by interactions between domains in Ded1 and initiation factor eIF4G that stabilizes a Ded1-eIF4F complex.

    La-related protein 1 (LARP1) binds the mRNA cap, blocking eIF4F assembly on TOP mRNAs

    Roni M Lahr, Bruno D Fonseca ... Andrea J Berman
    La-related protein 1 specifically and directly binds the 5' cap and first nucleotide of mRNAs encoding ribosomal proteins and translation factors, inhibiting the assembly of translation initiation factors on these messages and therefore their translation.

    The insulin receptor cellular IRES confers resistance to eIF4A inhibition

    Calla M Olson, Marissa R Donovan ... Michael T Marr II
    Utilizing a conserved mechanism, a ribosome can initiate translation from a site within the insulin receptor mRNA to maintain protein synthesis even when standard mechanisms of initiating translation have been inhibited by stress.

    Decapping factor Dcp2 controls mRNA abundance and translation to adjust metabolism and filamentation to nutrient availability

    Anil Kumar Vijjamarri, Xiao Niu ... Alan G Hinnebusch
    The yeast mRNA decapping enzyme Dcp1/Dcp2 repressses many genes whose products are required on poor carbon or nitrogen sources in nutrient-replete cells by mRNA decapping and degradation or translational repression, adding post-transcriptional controls to the transcriptional repression of these functions.
