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
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	Nucleus.
Miscellaneous	Present with 1360 molecules/cell in log phase SD medium. Ref.5
Sequence similarities	Belongs to the POP3 family.
