Abstract

MicroRNAs (miRNAs) are produced through a set of cleavages within a longer RNA, one of the nucleases involved in this process is Drosha. A subset of miRNAs (mirtrons) are matured through an alternative pathway that is Drosha-independent. These mirtrons may be the early ancestors of the majority of miRNAs that were expressed once Drosha function emerged.
