General Information
Term precatalytic spliceosome ID (Ontology) GO:0071011 (Gene Ontology)
Definition A spliceosomal complex that is formed by the recruitment of a preassembled U5-containing 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 associated snRNPs.[ PubMed:18322460 PubMed:19239890 ]
