Ribonucleases P/MRP protein subunit POP6

Known also as: RNA-processing protein POP6, RNases P/MRP 18.2 kDa subunit

Known abbreviations: POP6, YGR030C



  1. Component of RNase P complex ( which cleaves tRNA precursors to generate mature 5' ends)  (PMID: 11880623) and RNase MRP (which cleaves pre-rRNA complexes and mRNA in its 5' untranslated region - UTR)  (PMID: 14729943)
  2. pre-tRNA processing at 5' the end (PMID: 9620854)
  3. pre-rRNA processing at site A3 in the Interna Transcribed Spacer 1 (ITS1) (participation in synthesis of short form of 5.8S rRNA - 5.8S(S)) (PMID: 16618965, 9620854, 8247008)
  4. regulation of the cell cycle through the degradation of specific mRNAs (PMID: 14729943)
  5. Box C/D intron-encoded small nucleolar RNAs (snoRNAs) processing (PMID: 18713869)
  6. 6. Interaction with essential P3 subdomain of Rnase P/RNase MRP RNA (in a complex  with Pop7). Pop6/Pop7 comlex is probably involves in interaction of Pop1 with P3 domain as an adapter or mediator (PMID: 17717080)


Nucleolus (PMID: 11880623, 8247008)



Endonucleolytic cleavage of RNA, removing 5'-extranucleotides from tRNA precursor.
