Unformatted text preview: ed mRNAs are associated with proteins that prevent their translation." In some organisms, a protein brings 5 and 3 ends together by binding eIF4E and CPEB In Xenopus oocytes, translation is blocked by maskin protein, which does not allow eIF4A and 4G to bind. Ribosome can t bind this conformation 4 2/5/13 Amphibian ovulation  mRNAs translated 3 and 5 end of mRNAs brought together: Atomic force microscopy to visualize mRNA with bound eIF4E and eIF4G. Current model for the formation and use of microRNAs RNA half life and storage can be regulated by miRNAs Current model for the formation and use of microRNAs 5 2/5/13 mRNA Localization: Selective localization of mRNA messages in the cytoplasm is controlled by 3 UTR and often seen in oocytes. Bicoid mRNA is tethered to the anterior pole of egg and thus the protein is as well. 6...
