Abstract

A lariat cap is a naturally occurring substitute of a conventional mRNA cap and is found in a particular genomic setting in a few eukaryotic microorganisms. It is installed by the lariat capping ribozyme acting in cis. In principle, any RNA molecule in any organism can be equipped with a lariat cap in vivo when expressed downstream of a lariat capping ribozyme. Lariat capping is thus a versatile tool for studying the importance of the 5' end structure of RNA molecules. In this chapter, we present protocols to validate the presence of the lariat cap and measure the efficiency of in vivo cleavage by the lariat capping ribozyme.
