Hammerhead ribozyme cleavage of hamster prion pre-mRNA in complex cell-free model systems.

Abstract

The cleavage properties of a trans-acting hammerhead ribozyme targeted 51 bases upstream of the putative splicing branch point in the hamster prion pre-mRNA intron were investigated in cell-free model systems in vitro. The specificity of cleavage was demonstrated by the inability of this ribozyme to cleave a non-homologous synthetic message encoding part of… (More)
