Term Information

Accession
GO:0000349
Name
generation of catalytic spliceosome for first transesterification step
Ontology
biological_process
Synonyms
formation of catalytic spliceosome for first transesterification step, catalytic spliceosome assembly for first transesterification step, U12-type catalytic spliceosome formation for first transesterification step, U2-type catalytic spliceosome formation for first transesterification step, spliceosomal A2-2 complex biosynthesis, spliceosomal A2-2 complex formation, spliceosomal C1 complex biosynthesis, spliceosomal C1 complex formation
Alternate IDs
GO:0000356, GO:0000357
Definition
Formation of a catalytic spliceosome complex ready to perform the first splicing reaction. This occurs by an ATP-dependent conformational change of the pre-catalytic spliceosome. Source: GOC:krc, ISBN:0879695897
Comment
Note that this step represents the formation of the A2-2 complex (yeast) or the C1 complex (mammalian).
