General annotation (Comments)

Function	Required for processing of 5.8S rRNA (short form) at site A3 and for 5' and 3' processing of pre-tRNA. Ref.1 Ref.3
Catalytic activity	Endonucleolytic cleavage of RNA, removing 5'-extranucleotides from tRNA precursor.
Subunit structure	Component of nuclear RNase P and RNase MRP complexes. RNase P consists of an RNA moiety and at least 9 protein subunits including POP1, POP3, POP4, POP5, POP6, POP7, POP8, RPP1 and RPR2. RNase MRP complex consists of an RNA moiety and at least 10 protein subunits including POP1, POP3, POP4, POP5, POP6, POP7, POP8, RMP1, RPP1 and SNM1, many of which are shared with the RNase P complex. Ref.1
Subcellular location	Cytoplasm. Nucleus. Ref.4
Miscellaneous	Present with 846 molecules/cell in log phase SD medium. Ref.5
