General Information

General Information Comment Organism
additional information in plants, the protein Pop1p is associated with MRP RNAs, i.e. mitochondrial RNA processing RNAs which cleave the large rRNA precursor at the A3 site, and with the catalytic subunit of enzyme RNase P, either separately or in a single large complex. Pop1p-specific antibodies precipitate RNase P activity from wheat extracts. The eukaryotic RNase P consensus sequence with CR II and CR III that are signature elements specific for RNase P RNA Triticum aestivum
