precatalytic spliceosome

id: GO:0071011
name: precatalytic spliceosome
namespace: cellular_component
type: go
obsolete: False

Description: 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.
