The effect of loop size in antisense and target RNAs on the efficiency of antisense RNA control
(1992) In Nucleic Acids Research 20(24). p.6723-6732- Abstract
- Most natural antisense RNAs display a high degree of
secondary structure with stem-loops as their most
prominent feature. Mutations affecting the Inhibitory
activity of these RNAs most often map in or close to
loop regions in both the antisense and target RNAs.
The primary recognition loops often contain 5- 7
unpaired nucleotldes. Nucleotide changes in the loops
affect the binding rate and, hence, the inhibitory effect
on the activity of the target RNA. Here we address the
question whether loop sizes affect binding rates
between antisense and target RNAs, using the
replication control system of plasmid R1 as a model
system. By creating a series of loop size mutants we

show that loop size alterations have strong effects on
the binding rates between the two reactant RNAs In
vitro, and that most of the mutations analyzed display
corresponding effects on antisense RNA control In
vivo. Our data suggest that the three-dimensional
structures of antisense and target RNA stem-loops are
crucial for determining binding rates. The Implications
of these results for the design of efficient artificial
antisense RNA control systems are discussed. (Less)
