Efficient expression of ribozyme and reduction of stromelysin mRNA

... originally developed to increase the copy number and maintain catalytic activity of ribozyme expressed inside cells (Thompson et al., 1995a). To generate ribozyme with minimal flanking sequence we chose the U6 snRNA promoter since the U6 promoter is extragenic except for the "G" at +1. We have devel ...

Hammerhead ribozyme



The hammerhead ribozyme is a RNA molecule motif that catalyzes reversible cleavage and joining reactions at a specific site within an RNA molecule. It serves as a model system for research on the structure and properties of RNA, and is used for targeted RNA cleavage experiments, some with proposed therapeutic applications. Named for the resemblance of early secondary structure diagrams to a hammerhead shark, hammerhead ribozymes RNAs were originally discovered in two classes of plant virus-like RNAs: satellite RNAs and viroids. They have subsequently been found to be widely dispersed within many forms of life.The self-cleavage reactions, first reported in 1986, are part of a rolling circle replication mechanism. The hammerhead sequence is sufficient for self-cleavage and acts by forming a conserved three-dimensional tertiary structure.
