molecular function |
| GO:0003723 | | RNA binding | | Interacting selectively and non-covalently with an RNA molecule or a portion thereof. |
| GO:0004519 | | endonuclease activity | | Catalysis of the hydrolysis of ester linkages within nucleic acids by creating internal breaks. |
| GO:0016787 | | hydrolase activity | | Catalysis of the hydrolysis of various bonds, e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc. Hydrolase is the systematic name for any enzyme of EC class 3. |
| GO:0004518 | | nuclease activity | | Catalysis of the hydrolysis of ester linkages within nucleic acids. |
| GO:0004526 | | ribonuclease P activity | | Catalysis of the endonucleolytic cleavage of RNA, removing 5' extra nucleotides from tRNA precursor. |
| GO:0004540 | | ribonuclease activity | | Catalysis of the hydrolysis of phosphodiester bonds in chains of RNA. |
biological process |
| GO:0090502 | | RNA phosphodiester bond hydrolysis, endonucleolytic | | The chemical reactions and pathways involving the hydrolysis of internal 3',5'-phosphodiester bonds in one or two strands of ribonucleotides. |
| GO:0006379 | | mRNA cleavage | | Any process in which a pre-mRNA or mRNA molecule is cleaved at specific sites or in a regulated manner. |
| GO:0006364 | | rRNA processing | | Any process involved in the conversion of a primary ribosomal RNA (rRNA) transcript into one or more mature rRNA molecules. |
| GO:0001682 | | tRNA 5'-leader removal | | Generation of the mature 5'-end of the tRNA, usually via an endonucleolytic cleavage by RNase P. |
| GO:0008033 | | tRNA processing | | The process in which a pre-tRNA molecule is converted to a mature tRNA, ready for addition of an aminoacyl group. |
cellular component |
| GO:0005737 | | cytoplasm | | All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
| GO:0000172 | | ribonuclease MRP complex | | A ribonucleoprotein complex that contains an RNA molecule of the snoRNA family, and cleaves the rRNA precursor as part of rRNA transcript processing. It also has other roles: In S. cerevisiae it is involved in cell cycle-regulated degradation of daughter cell-specific mRNAs, while in mammalian cells it also enters the mitochondria and processes RNAs to create RNA primers for DNA replication. |
| GO:0030677 | | ribonuclease P complex | | A ribonucleoprotein complex that catalyzes cleavage of the leader sequence of precursor tRNAs (pre-tRNAs), generating the mature 5' end of tRNAs. |
