ABSTRACT:
The invention pertains to a multimeric self-cleaving ribozyme comprising multiple repeating units, wherein each unit comprises a ribozyme containing a catalytic domain and an antisense domain, and a target recognition sequence or portion thereof recognized by the antisense domain of the ribozyme and comprising a ribozyme cleavage site to facilitate self-cleavage. The invention also pertains to constructs comprising DNA encoding the multimeric self-cleaving ribozyme, cells stably transformed with these constructs, and methods of cleaving RNA, regulating gene expression and generating molecular weight ladders utilizing the multimeric self-cleaving ribozyme.
