Cells activate stress response pathways to survive adverse conditions. Such responses involve the inhibition of global cap-dependent translation. This inhibition is a block that essential transcripts must escape via alternative methods of translation initiation, e.

Treatments that inhibit the canonical translation factor EIF4G1 have little or no effect on the ability of the Insr and Igf1r cellular IRESes to promote translation. Transcripts for two cellular receptors contain RNA elements that facilitate translation initiation without intact EIF4G1.

, a fast-growing Gram-negative bacterium, is gaining interest as a platform for rapid biotechnology applications and metabolic engineering. Only a few bacteriophages that infect this bacterium have been identified. Here, we describe the isolation and characterization of two bacteriophages isolated from Hatches Creek, Wellfleet, Massachusetts.

Twinfilin is a conserved in vivo binding partner of CP, yet the significance of this interaction has remained a mystery. Here, we discover that the C-terminal tail of Twinfilin harbors a CP-interacting (CPI) motif, identifying it as a novel CPI-motif protein.
