GO:0005684 U2-type spliceosomal complex

Term Information

ID GO:0005684
Name U2-type spliceosomal complex
Ontology Cellular Component
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.
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.

ID Mapping

QuickGO maps between different identifier types by using a combination of mapping files provided by the databases, and using identifier cross-references supplied by UniProtKB.

If more than one identifier type needs to be used to map all required sequences, drag the selected databases to change the order in which identifiers are found.
