Example sentences for: cap-dependent

How can you use “cap-dependent” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • eIF4E gene transcription is enhanced in response to mitogenic stimulation and may be mediated by c-myc [ 3 ] . Phosphorylation of eIF4E by the protein kinase Mnk1 increases its affinity for the cap, and thus increases cap-dependent initiation of translation [ 4 5 6 ] . An inhibitor of eIF4E, 4E binding protein (4EBP), is also regulated by phosphorylation.

  • IRES entirely contained within a translated ORF has been shown in the MMLV gag [ 47 ] , and host mRNA encoding p110 PITSLREand p58 PITSLRE [ 48 ] . Along these lines, cap-dependent translation may be cell cycle regulated, especially when cells are arrested at the G2 phase of the cell cycle, where the cap-dependent translation of most cellular host cell mRNAs is inhibited [ 49 50 51 ] .

  • Expression of constitutively active 4EBP-1 should lead to a global decrease in cap-dependent translation which could lead to cell cycle arrest.

  • Phosphorylation of 4EBP disrupts its ability to bind eIF4E, freeing eIF4E to bind eIF4G, which functions to recruit additional components of the initiation complex [ 7 8 ] . The net result is that phosphorylation of 4EBP enhances cap-dependent translation initiation.

  • A novel finding of the experiments above is that synthesis of endogenous p27 Kip1is enhanced under conditions that are expected to reduce cap-dependent translation.
