SmY RNA

SmY ribonucleic acids (SmY RNAs) are a family of small nuclear RNAs found in some species of nematode worms. They are thought to be involved in mRNA trans-splicing.SmY RNAs are about 70-90 nucleotides long and share a common secondary structure, with two stem-loops flanking a consensus binding site for Sm protein.Sm protein is a shared component of spliceosomal snRNPs.
