Abstract:
Here we present first dinucleotide affinity resins for purification of proteins that specifically recognize the 5' end of mRNA. Constructed resins possess either a naturally occurring mono- or trimethylated cap or their analogues resistant towards enzymatic degradation, bearing a CH(2) bridge between β and γ position of the 5',5'-triphosphate chain. All cap analogues were attached to a polymer support (EAH-Sepharose) through the carboxylic group that had been generated by derivatization of the 2',3'-cis diol of the second nucleotide in the cap structure with levulinic acid.

Pre-mRNA Processing: Modification of pre-mRNA Ends
Once about 20-40 ribonucleotides have been joined together by RNA polymerase, a group of enzymes adds a cap to the 5' end of the growing transcript. In this process, a 5' phosphate is replaced by modified guanosine that has a methyl group attached (7-methyl guanosine). This 5' cap helps the cell...
