U12-type prespliceosome

Term Information

Accession
GO:0071015
Name
U12-type prespliceosome
Ontology
cellular_component
Synonyms
minor prespliceosome, AT-AC prespliceosome, mammalian U12-type spliceosomal complex A, yeast U12-type spliceosomal complex B
Alternate IDs

Definition
A spliceosomal complex that is formed by the cooperative binding of the heterodimeric U11/U12 snRNP to the 5' splice site and the branch point sequence. The U12-type prespliceosome includes many proteins in addition to those found in the U11/U12 heterodimeric snRNPs. Commitment to a given pair of 5' and 3' splice sites occurs at the time of prespliceosome formation. Source: GOC:krc, PMID:16201866, GOC:ab, GOC:mah, PMID:10197985
