CC   -!- FUNCTION: Component of ribonuclease P, a protein complex that generates
CC       mature tRNA molecules by cleaving their 5'-ends.
CC       {ECO:0000269|PubMed:9620854}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=Endonucleolytic cleavage of RNA, removing 5'-extranucleotides
CC         from tRNA precursor.; EC=3.1.26.5;
CC   -!- COFACTOR:
CC       Name=Zn(2+); Xref=ChEBI:CHEBI:29105; Evidence={ECO:0000250};
CC       Note=Binds 1 zinc ion per subunit. {ECO:0000250};
CC   -!- SUBUNIT: Component of nuclear RNase P. RNase P consists of an RNA
CC       moiety and at least 9 protein subunits including POP1, POP3, POP4,
CC       POP5, POP6, POP7, POP8, RPP1 and RPR2, many of which are shared with
CC       the RNase MPR complex. {ECO:0000269|PubMed:9620854}.
CC   -!- INTERACTION:
CC       P40571; P38336: POP4; NbExp=3; IntAct=EBI-25408, EBI-13646;
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000269|PubMed:14562095}.
CC   -!- MISCELLANEOUS: Present with 2070 molecules/cell in log phase SD medium.
CC       {ECO:0000269|PubMed:14562106}.
CC   -!- SIMILARITY: Belongs to the eukaryotic/archaeal RNase P protein
CC       component 4 family. {ECO:0000305}.
