GO:0000389 | mRNA 3'-splice site recognition | biological_process | Recognition of the intron 3'-splice site by components of the assembling U2- or U12-type spliceosome. [GOC:krc, ISBN:0879695897] |
GO:0000398 | mRNA splicing, via spliceosome | biological_process | 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. [GOC:krc, ISBN:0198506732, ISBN:0879695897] |
GO:0006397 | mRNA processing | biological_process | Any process involved in the conversion of a primary mRNA transcript into one or more mature mRNA(s) prior to translation into polypeptide. [GOC:mah] |
GO:1903241 | U2-type prespliceosome assembly | biological_process | The aggregation, arrangement and bonding together of a set of components to form an U2-type prespliceosome. [GO_REF:0000079, GOC:TermGenie, PMID:12374752] |
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:0005681 | spliceosomal complex | cellular_component | 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. [GOC:editors, GOC:mah, ISBN:0198547684, PMID:19239890] |
GO:0005684 | U2-type spliceosomal complex | cellular_component | Any spliceosomal complex that forms during the splicing of a messenger RNA primary transcript to excise an intron that has canonical consensus sequences near the 5' and 3' ends. [GOC:krc, GOC:mah, PMID:11343900] |
GO:0005686 | U2 snRNP | cellular_component | A ribonucleoprotein complex that contains small nuclear RNA U2, a heptameric ring of Sm proteins, as well as several proteins that are unique to the U2 snRNP, most of which remain associated with the U2 snRNA both while the U2 snRNP is free or assembled into a series of spliceosomal complexes. [GOC:krc, GOC:mah, ISBN:0879695897] |
GO:0016607 | nuclear speck | cellular_component | A discrete extra-nucleolar subnuclear domain, 20-50 in number, in which splicing factors are seen to be localized by immunofluorescence microscopy. [http://www.cellnucleus.com/] |
GO:0071005 | U2-type precatalytic spliceosome | cellular_component | A spliceosomal complex that is formed by the recruitment of the preassembled U4/U6.U5 tri-snRNP to the prespliceosome. Although all 5 snRNPs are present, the precatalytic spliceosome is catalytically inactive. The precatalytic spliceosome includes many proteins in addition to those found in the U1, U2 and U4/U6.U5 snRNPs. [GOC:ab, GOC:krc, GOC:mah, PMID:18322460, PMID:19239890] |
GO:0071013 | catalytic step 2 spliceosome | cellular_component | A spliceosomal complex that contains three snRNPs, including U5, bound to a splicing intermediate in which the first catalytic cleavage of the 5' splice site has occurred. The precise subunit composition differs significantly from that of the catalytic step 1, or activated, spliceosome, and includes many proteins in addition to those found in the associated snRNPs.
