U12-type spliceosomal complex

Term ID

GO:0005689

Synonyms

• AT-AC spliceosomal complex
• minor (U12-type) spliceosomal complex
• minor spliceosomal complex

Definition

Any spliceosomal complex that forms during the splicing of a messenger RNA primary transcript to excise an intron; the series of U12-type spliceosomal complexes is involved in the splicing of the majority of introns that contain atypical AT-AC terminal dinucleotides, as well as other non-canonical introns. The entire splice site signal, not just the terminal dinucleotides, is involved in determining which spliceosome utilizes the site. (2)
