| molecular function |
|---|
| | GO:0008409 | | 5'-3' exonuclease activity | | Catalysis of the hydrolysis of ester linkages within nucleic acids by removing nucleotide residues from the 5' end. |
| | 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:0004521 | | endoribonuclease activity | | Catalysis of the hydrolysis of ester linkages within ribonucleic acid 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: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:0005515 | | protein binding | | Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules). |
| 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:0031124 | | mRNA 3'-end processing | | Any process involved in forming the mature 3' end of an mRNA molecule. |
| | GO:0006398 | | mRNA 3'-end processing by stem-loop binding and cleavage | | Any mRNA 3'-end processing that involves the binding to and cleavage of a stem-loop structure. For example, histone mRNAs contain a highly conserved stem-loop sequence at the 3' end of the mRNA with a 6 base pairs (bp) stem and a 4-nt loop. The mRNA is cleaved between these two elements, after the fourth or fifth nucleotide, which is typically an adenosine. |
| | 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:0006406 | | mRNA export from nucleus | | The directed movement of mRNA from the nucleus to the cytoplasm. |
| | GO:0006378 | | mRNA polyadenylation | | The enzymatic addition of a sequence of 40-200 adenylyl residues at the 3' end of a eukaryotic mRNA primary transcript. |
| | GO:0006397 | | mRNA processing | | Any process involved in the conversion of a primary mRNA transcript into one or more mature mRNA(s) prior to translation into polypeptide. |
| | GO:0000398 | | mRNA splicing, via spliceosome | | The joining together of exons from one or more primary transcripts of messenger RNA (mRNA) and the excision of intron sequences, via a spliceosomal mechanism, so that mRNA consisting only of the joined exons is produced. |
| | GO:0090305 | | nucleic acid phosphodiester bond hydrolysis | | The nucleic acid metabolic process in which the phosphodiester bonds between nucleotides are cleaved by hydrolysis. |
| | GO:0006369 | | termination of RNA polymerase II transcription | | The process in which the synthesis of an RNA molecule by RNA polymerase II using a DNA template is completed. |
| cellular component |
|---|
| | GO:0030529 | | intracellular ribonucleoprotein complex | | An intracellular macromolecular complex containing both protein and RNA molecules. |
| | GO:0005847 | | mRNA cleavage and polyadenylation specificity factor complex | | A multisubunit complex that binds to the canonical AAUAAA hexamer and to U-rich upstream sequence elements on the pre-mRNA, thereby stimulating the otherwise weakly active and nonspecific polymerase to elongate efficiently RNAs containing a poly(A) signal. |
| | GO:0005654 | | nucleoplasm | | That part of the nuclear content other than the chromosomes or the nucleolus. |
| | 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. |
