General Information
Term trans assembly of SL-containing precatalytic spliceosome ID (Ontology) GO:0000352 (Gene Ontology)
Definition Assembly of a spliceosomal complex containing the SL RNA and the pre-mRNA to be joined, as well as all the spliceosomal snRNPs involved in trans leader splicing. Formation of the trans leader spliceosome brings together the quadruple SL/U4/U5/U6 snRNP and the complex of the U2 snRNP with the splice site of the pre-mRNA.[ ISBN:0879695897 ]
Also Known As "trans assembly of spliced leader-containing precatalytic spliceosome"
