Words similar to cap-dependent
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.
