catalytic step 2 spliceosome +   
post-mRNA release spliceosomal complex +   
post-spliceosomal complex +   
precatalytic spliceosome +   
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.
