CC   -!- FUNCTION: Part of ribonuclease P, a protein complex that generates
CC       mature tRNA molecules by cleaving their 5'-ends. {ECO:0000255|HAMAP-
CC       Rule:MF_00755, ECO:0000269|PubMed:18558617,
CC       ECO:0000269|PubMed:21683084, ECO:0000269|PubMed:22298511}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=Endonucleolytic cleavage of RNA, removing 5'-extranucleotides
CC         from tRNA precursor.; EC=3.1.26.5; Evidence={ECO:0000255|HAMAP-
CC         Rule:MF_00755};
CC   -!- SUBUNIT: Consists of a catalytic RNA component and at least 4-5 protein
CC       subunits. Forms a subcomplex with Rnp3 which stimulates the catalytic
CC       RNA. {ECO:0000255|HAMAP-Rule:MF_00755, ECO:0000269|PubMed:18558617,
CC       ECO:0000269|PubMed:21683084, ECO:0000269|PubMed:22298511}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00755}.
CC   -!- SIMILARITY: Belongs to the eukaryotic/archaeal RNase P protein
CC       component 2 family. {ECO:0000255|HAMAP-Rule:MF_00755}.
