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.

Webb20 feb. 2008 · Ribosome shunt is a mechanism of eukaryotic translation initiation that combines features of both 5′-end dependent scanning and internal ribosome entry. It has been discovered in plants, first for Cauliflower mosaic virus (CaMV) [1], [2] and then for Rice tungro bacilliform virus (RTBV) [3]. WebbThe virus multiplies in mid-villus enterocytes, which are then sloughed leading to villar blunting and fusion of non-epithelialized basement membranes, thus decreasing digestive surface and enzymatic activity resulting in maldigestive/malabsorptive diarrhea.

Ribosome shunting process was first discovered in CaMV in 1993, and then was reported in Rice tungro bacilliform virus (RTBV) in 1996. The mechanism of ribosome shunting in RTBV resembles that in CaMV: it also requires the first short ORF as well as a following strong secondary structure. Swapping of the … Visa mer Ribosome shunting is a mechanism of translation initiation in which ribosomes bypass, or "shunt over", parts of the 5' untranslated region to reach the start codon. However, a benefit of ribosomal shunting is that it … Visa mer Sendai virus Y proteins are initiated by ribosome shunting. Among 8 primary translation products of Sendai virus P/C mRNA, leaky scanning accounts for translation of protein … Visa mer Translation of Cauliflower mosaic virus (CaMV) 35S RNA is initiated by a ribosome shunt. The 35S RNA of CaMV contains a ~600 nucleotide leader sequence which contains 7-9 short open reading frames (sORFs) depending on the strain.
