Term Information [More information on U2-type prespliceosome]

Accession
GO:0071004
Name
U2-type prespliceosome
Ontology
cellular_component
Synonyms
major prespliceosome, GT-AG prespliceosome, mammalian U2-type spliceosomal complex A, yeast U2-type spliceosomal complex B
Definition
A spliceosomal complex that is formed by association of the 5' splice site with the U1 snRNP, while the branch point sequence is recognized by the U2 snRNP. The prespliceosome includes many proteins in addition to those found in the U1 and U2 snRNPs. Commitment to a given pair of 5' and 3' splice sites occurs at the time of prespliceosome formation.
