Term: U2-type precatalytic spliceosome
Accession: GO:0071005
browse the term
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.
Synonyms: exact_synonym: major precatalytic spliceosome
narrow_synonym: GT-AG precatalytic spliceosome; mammalian U2-type spliceosomal complex B; mammalian U2-type spliceosomal complex B1
related_synonym: yeast U12-type spliceosomal complex A2-1
