Ribonucleases P/MRP protein subunit Pop8 (IPR020347)

Short name: Pop8

Family relationships

None.

Description

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 [PMID: 9620854]. 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. This protein is found at the nucleus.
