Ribosomal shunting
Webb5 nov. 2015 · Translation initiation is stimulated by m 6 A modification of the 3′ UTR of mRNA through recruitment of YTHDF1, which subsequently recruits the translation initiation complex. (E) Ribosome shunting. Ribosomal RNA base pairs with mRNA leading to the translocation of 40S subunit from the cap region to internal start codons for … Webb15 okt. 2006 · The results of our systematic mutational, structural and functional analysis of the 5′ UTR led us to conclude that a ribosome-shunting mechanism - rather than leaky scanning, ribosomal reinitiation, or internal ribosome entry site (IRES)-mediated initiation - controls the translation of regA mRNA.

WebbRibosomal shunting has been found to mediate translation initiation on a few viral mRNAs, including cauliflower mosaic virus 35S mRNA ( Futterer et al. 1993) and adenovirus late mRNAs ( Yueh and Schneider 1996) and on the cellular mRNA that encodes heat shock protein 70 ( Yueh and Schneider 2000 ).

By shunting nitrogen directly from ammonium to N(2), anaerobic ammonium oxidation promotes the removal of fixed nitrogen in the oceans. property insurance redlands ca
