| GO:0090502 | RNA phosphodiester bond hydrolysis, endonucleolytic | biological_process | The chemical reactions and pathways involving the hydrolysis of internal 3',5'-phosphodiester bonds in one or two strands of ribonucleotides. [GOC:dph, GOC:tb] |
| GO:0032039 | integrator complex | cellular_component | A protein complex that stably associates with the C-terminus of RNA polymerase II and mediates 3'-end processing of small nuclear RNAs generated by RNA polymerase II. [PMID:16239144] |
| GO:0005634 | nucleus | cellular_component | 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. [GOC:go_curators] |
| GO:0005654 | nucleoplasm | cellular_component | That part of the nuclear content other than the chromosomes or the nucleolus. [GOC:ma, ISBN:0124325653] |
| GO:0005515 | protein binding | molecular_function | Binding to a protein. [GOC:go_curators] |
| GO:0005737 | cytoplasm | cellular_component | The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. [ISBN:0198547684] |
| GO:0110165 | cellular anatomical entity | cellular_component | A part of a cellular organism that is either an immaterial entity or a material entity with granularity above the level of a protein complex but below that of an anatomical system. Or, a substance produced by a cellular organism with granularity above the level of a protein complex. [GOC:kmv] |
| GO:0004521 | endoribonuclease activity | molecular_function | Catalysis of the hydrolysis of ester linkages within ribonucleic acid by creating internal breaks. [GOC:mah, ISBN:0198547684] |
| GO:0016180 | snRNA processing | biological_process | Any process involved in the conversion of a primary small nuclear RNA (snRNA) transcript into a mature snRNA molecule. [GOC:jl] |
| GO:0005829 | cytosol | cellular_component | The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes. [GOC:hjd, GOC:jl] |
