U11 spliceosomal RNA
The U11 snRNA (small nuclear ribonucleic acid) is an important non-coding RNA in the minor spliceosome protein complex, which activates the alternative splicing mechanism. The minor spliceosome is associated with similar protein components as the major spliceosome. It uses U11 snRNA to recognize the 5' splice site (functionally equivalent to U1 snRNA) while U12 snRNA binds to the branchpoint to recognize the 3' splice site (functionally equivalent to U2 snRNA).
