Term Information

Accession
GO:0005684
Name
U2-type spliceosomal complex
Ontology
cellular_component
Synonyms
major (U2-type) spliceosomal complex, major spliceosomal complex, GT-AG spliceosome
Alternate IDs
None
Definition
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. Source: GOC:krc, GOC:mah, PMID:11343900
Comment
A U2-type complex refers to any of the snRNP-based complexes that form during splicing that uses U2 (as opposed to U12). There are complexes that form during U2-splicing that don't necessarily contain the U2 snRNP.
