small nuclear ribonucleoprotein 25kDa (U11/U12)

Two types of spliceosomes catalyze splicing of pre-mRNAs. The major U2-type spliceosome is found in all eukaryotes and removes U2-type introns, which represent more than 99% of pre-mRNA introns. The minor U12-type spliceosome is found in some eukaryotes and removes U12-type introns, which are rare and have distinct splice consensus signals. The U12-type spliceosome consists of several small nuclear RNAs and associated proteins. This gene encodes a 25K protein that is a component of the U12-type spliceosome.

RNA, U11 small nuclear

Predicted to enable pre-mRNA 5'-splice site binding activity. Predicted to be involved in mRNA 5'-splice site recognition. Predicted to act upstream of or within RNA splicing. Predicted to be part of U11 snRNP. [provided by Alliance of Genome Resources, Mar 2025]

small nuclear ribonucleoprotein 35kDa (U11/U12)

The protein encoded by this gene is a homolog of the U1-snRNP binding protein. The N-terminal half contains a RNA recognition motif and the C-terminal half is rich in Arg/Asp and Arg/Glu dipeptides, which is a characteristic of a variety of splicing factors. This protein is a component of the U11/U12 small nuclear ribonucleoproteins (snRNP) that form part of the U12-type spliceosome. Alternative splicing results in multiple transcript variants encoding two distinct isoforms and representing a non-protein coding variant. [provided by RefSeq, Aug 2013]
