Abstract

Ribonuclease P (RNase P) has been hitherto well known as a catalytic ribonucleoprotein that processes the 5′ leader sequence of precursor tRNA. Recent studies, however, reveal a new role for nuclear forms of RNase P in the transcription of tRNA genes by RNA polymerase (pol) III, thus linking transcription with processing in the regulation of tRNA gene expression. However, RNase P is also essential for the transcription of other small noncoding RNA genes, whose precursor transcripts are not recognized as substrates for this holoenzyme. Accordingly, RNase P can act solely as a transcription factor for pol III, a role that seems to be conserved in eukarya.
