Synonyms
cis assembly of U12-type pre-catalytic spliceosome, cis assembly of U2-type pre-catalytic spliceosome, formation of spliceosomal A2-1 complex, formation of spliceosomal B1 complex, spliceosomal A2-1 complex biosynthesis, spliceosomal A2-1 complex formation, spliceosomal B1 complex biosynthesis, spliceosomal B1 complex formation
Alternate IDs

Definition
Assembly of a spliceosomal complex containing the intact pre-mRNA and all of the spliceosomal snRNPs. This occurs when the tri-snRNP associates with the pre-mRNA and associated snRNPs in an ATP-dependent manner. Source: GOC:krc, GOC:mtg_mpo, ISBN:0879695897
Comment
Note that this step represents formation of the A2-1 complex (yeast) or the B1 complex (mammals).
