AmiGO 2: Term Details for "U2-type precatalytic spliceosome" (GO:0071005)

Accession: GO:0071005
Name: U2-type precatalytic spliceosome
Ontology: cellular_component
Synonyms: major precatalytic spliceosome, yeast U12-type spliceosomal complex A2-1, GT-AG precatalytic spliceosome, mammalian U2-type spliceosomal complex B, mammalian U2-type spliceosomal complex B1
Alternate IDs: None
Definition: 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. Source: GOC:krc, PMID:19239890, GOC:ab, GOC:mah, PMID:18322460
