| | GO:0008408 | | 3'-5' exonuclease activity | | Catalysis of the hydrolysis of ester linkages within nucleic acids by removing nucleotide residues from the 3' end. |
| | GO:0003723 | | RNA binding | | Interacting selectively and non-covalently with an RNA molecule or a portion thereof. |
| | GO:0004527 | | exonuclease activity | | Catalysis of the hydrolysis of ester linkages within nucleic acids by removing nucleotide residues from the 3' or 5' end. |
| | GO:0071207 | | histone pre-mRNA stem-loop binding | | Interacting selectively and non-covalently with a conserved stem-loop structure found in histone pre-mRNAs. |
| | 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:0046872 | | metal ion binding | | Interacting selectively and non-covalently with any metal ion. |
| | GO:0004518 | | nuclease activity | | Catalysis of the hydrolysis of ester linkages within nucleic acids. |
| | GO:0003676 | | nucleic acid binding | | Interacting selectively and non-covalently with any nucleic acid. |
| | GO:0019843 | | rRNA binding | | Interacting selectively and non-covalently with ribosomal RNA. |
| | GO:0043022 | | ribosome binding | | Interacting selectively and non-covalently with any part of a ribosome. |
| biological process |
|---|
| | GO:0000467 | | exonucleolytic trimming to generate mature 3'-end of 5.8S rRNA from tricistronic rRNA transcript (SSU-rRNA, 5.8S rRNA, LSU-rRNA) | | Exonucleolytic digestion of a pre-rRNA molecule to generate the mature 3'-end of a 5.8S rRNA molecule derived from an originally tricistronic pre-rRNA transcript that contained the Small Subunit (SSU) rRNA, the 5.8S rRNA, and the Large Subunit (LSU) rRNA in that order from 5' to 3' along the primary transcript. |
| | GO:0031047 | | gene silencing by RNA | | Any process in which RNA molecules inactivate expression of target genes. |
| | GO:0071044 | | histone mRNA catabolic process | | The chemical reactions and pathways resulting in the breakdown of histone messenger RNA (mRNA). |
| | GO:0031125 | | rRNA 3'-end processing | | Any process involved in forming the mature 3' end of an rRNA molecule. |
| | GO:0006364 | | rRNA processing | | Any process involved in the conversion of a primary ribosomal RNA (rRNA) transcript into one or more mature rRNA molecules. |
| cellular component |
|---|
| | GO:0005737 | | cytoplasm | | All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
| | GO:0071204 | | histone pre-mRNA 3'end processing complex | | A ribonucleoprotein that binds to specific sites in, and is required for cleavage of, the 3'-end of histone pre-mRNAs. The complex contains the U7 snRNP and additional proteins, including the stem-loop binding protein (SLBP) and the exonuclease 3'hExo/Eri-1. |
| | GO:0005730 | | nucleolus | | A small, dense body one or more of which are present in the nucleus of eukaryotic cells. It is rich in RNA and protein, is not bounded by a limiting membrane, and is not seen during mitosis. Its prime function is the transcription of the nucleolar DNA into 45S ribosomal-precursor RNA, the processing of this RNA into 5.8S, 18S, and 28S components of ribosomal RNA, and the association of these components with 5S RNA and proteins synthesized outside the nucleolus. This association results in the formation of ribonucleoprotein precursors; these pass into the cytoplasm and mature into the 40S and 60S subunits of the ribosome. |
| | GO:0005634 | | nucleus | | A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent. |
