Pop8 is a component of ribonuclease P, a protein complex that generates mature tRNA molecules by cleaving their 5'-ends. It is also a component of Ribonuclease MRP, which cleaves pre-rRNA sequences [1]. Ribonuclease P consists of an RNA moiety and at least 9 protein subunits including POP1, POP3, POP4, POP5, POP6, POP7, POP8, RPP1 and RPR2. Ribonuclease 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 Ribonuclease P complex [2]. Pop8 interacts with Pop5 and Rpp1 to form the Pop5-Pop8-(Rpp1)2 heterotetramer, which is part of the arm module of the p[protein hook [2].	Domain

This family consists of several archaeal and eukaryotic proteins. The archaeal proteins are found to be expressed within ribosomal operons and several of the sequences are described as ribonuclease P protein subunit p29 proteins [1,2]. The structure of the RNase P subunit, Rpp29, from Methanobacterium thermoautotrophicum has been determined. Mth Rpp29 is a member of the oligonucleotide/oligosaccharide binding fold family. It contains a structured beta-barrel core and unstructured N- and C-terminal extensions bearing several highly conserved amino acid residues that could be involved in RNA contacts in the protein-RNA complex [2]. Rpp29 catalyses the endonucleolytic cleavage of RNA, removing 5'-extranucleotides from tRNA precursor. It interacts with the Rpp25 and Pop5 subunits.	Domain

This entry represents the C-terminal domain of human Ribonuclease P/MRP protein subunit POP1 and similar eukaryotic sequences. POP1 is a component of Ribonuclease P that cleaves the 5' leader from precursor tRNAs. The C-terminal domain of POP1 interacts with H1 RNA and has a stabilizing role. This domain adopts a beta-barrel structure that is structurally very similar to the C-terminal beta-barrel domains of eIF2 gamma, EF-Tu and tRNA thiouridylase MnmA [1].	Domain

This entry represents a conserved region approximately 150 residues long located towards the N-terminus of the POP1 subunit that is common to both the RNase MRP and RNase P ribonucleoproteins (EC:3.1.26.5) [1].
