| GO:0043021 | | ribonucleoprotein complex binding | | Interacting selectively and non-covalently with any complex of RNA and protein. |
biological process |
| GO:0008380 | | RNA splicing | | The process of removing sections of the primary RNA transcript to remove sequences not present in the mature form of the RNA and joining the remaining sections to form the mature form of the RNA. |
| 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:0045070 | | positive regulation of viral genome replication | | Any process that activates or increases the frequency, rate or extent of viral genome replication. |
| GO:0006461 | | protein complex assembly | | The aggregation, arrangement and bonding together of a set of components to form a protein complex. |
| GO:0006457 | | protein folding | | The process of assisting in the covalent and noncovalent assembly of single chain polypeptides or multisubunit complexes into the correct tertiary structure. |
| GO:0000413 | | protein peptidyl-prolyl isomerization | | The modification of a protein by cis-trans isomerization of a proline residue. |
cellular component |
| GO:0071001 | | U4/U6 snRNP | | A ribonucleoprotein complex that contains base-paired U4 and U6 small nuclear RNAs. |
| GO:0046540 | | U4/U6 x U5 tri-snRNP complex | | A ribonucleoprotein complex formed by the association of the U4/U6 and U5 small nuclear ribonucleoproteins. |
| GO:0005737 | | cytoplasm | | All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
| GO:0016607 | | nuclear speck | | A discrete extra-nucleolar subnuclear domain, 20-50 in number, in which splicing factors are seen to be localized by immunofluorescence microscopy. |
| 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. |
| GO:0005681 | | spliceosomal complex | | Any of a series of ribonucleoprotein complexes that contain snRNA(s) and small nuclear ribonucleoproteins (snRNPs), and are formed sequentially during the spliceosomal splicing of one or more substrate RNAs, and which also contain the RNA substrate(s) from the initial target RNAs of splicing, the splicing intermediate RNA(s), to the final RNA products. During cis-splicing, the initial target RNA is a single, contiguous RNA transcript, whether mRNA, snoRNA, etc., and the released products are a spliced RNA and an excised intron, generally as a lariat structure. During trans-splicing, there are two initial substrate RNAs, the spliced leader RNA and a pre-mRNA. |

cellular component |
| GO:0015030 | | Cajal body | | A class of nuclear body, first seen after silver staining by Ramon y Cajal in 1903, enriched in small nuclear ribonucleoproteins, and certain general RNA polymerase II transcription factors; ultrastructurally, they appear as a tangle of coiled, electron-dense threads roughly 0.5 micrometers in diameter; involved in aspects of snRNP biogenesis; the protein coilin serves as a marker for Cajal bodies. Some argue that Cajal bodies are the sites for preassembly of transcriptosomes, unitary particles involved in transcription and processing of RNA. |
