Rpp21, a protein subunit of human nuclear
ribonuclease P
(
RNase P
) was cloned by virtue of its homology with Rpr2p, an essential subunit of Saccharomyces cerevisiae nuclear
RNase P
. Rpp21 is encoded by a gene that resides in the class I gene cluster of the
major histocompatibility complex
, is associated with highly purified
RNase P
, and binds precursor tRNA. Rpp21 is predominantly localized in the nucleoplasm but is also observed in nucleoli and Cajal bodies when expressed at high levels. Intron retention and splice-site selection in Rpp21 precursor mRNA regulate the intranuclear distribution of the protein products and their association with the
RNase P
holoenzyme. Our study reveals that dynamic nuclear structures that include nucleoli, the perinucleolar compartment and Cajal bodies are all involved in the production and assembly of human
RNase P
.
