GO:0000363 first U12-type spliceosomal transesterification activity

This term is obsolete.
This term was made obsolete because the activities used in the U2- and U12-type complexes are the same. The cellular component ontology should (and does) represent the two different complexes, but the molecular function ontology should not.

Term Information

ID GO:0000363
Name first U12-type spliceosomal transesterification activity
Ontology Molecular Function
Definition OBSOLETE. Catalysis of the first transesterification reaction of U12-type spliceosomal mRNA splicing. The intron branch site adenosine is the nucleophile attacking the 5' splice site, resulting in cleavage at this position. In cis splicing, this is the step that forms a lariat structure of the intron RNA, which is still joined to the 3' exon. The catalytic site is thought to be formed by U6atac snRNA and/or U2atac snRNA, and/or associated proteins.
