Ribonucleases P/MRP protein subunit POP8

Known also as: RNA-processing protein POP8, RNases P/MRP 15.5 kDa subunit

Known abbreviations: POP8, YBL018C, YBL0301



  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. regulation of the cell cycle through the degradation of specific mRNAs (PMID: 14729943) 
  4. Box C/D intron-encoded small nucleolar RNAs (snoRNAs) processing ( PMID: 18713869)
Nucleolus (PMID: 11880623, 8247008)

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