Term:U12-type precatalytic spliceosome
go back to main search page
Accession:GO:0071016 term browser browse the term
Definition:A spliceosomal complex that is formed by the recruitment of the preassembled U4atac/U6atac.U5 tri-snRNP to the U12-type 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 U11, U12 and U4atac/U6atac.U5 snRNPs.
Synonyms:exact_synonym: minor precatalytic spliceosome
 narrow_synonym: AT-AC precatalytic spliceosome;   mammalian U12-type spliceosomal complex B;   mammalian U12-type spliceosomal complex B1;   yeast U12-type spliceosomal complex A2-1
