A small nuclear RNA (snRNA) is one of many small RNA species confined to the nucleus; several of the snRNAs are involved in splicing or other RNA processing reactions. Small cytoplasmic RNAs (scRNA) are present in the cytoplasm and (sometimes are also found in the nucleus).
What is the function of the snRNA?
Many small nuclear ribonucleic acids (snRNAs) of eukaryotic cells are involved in the maturation of primary transcripts of messenger RNAs (mRNAs). Certain snRNAs are involved in the formation and function of the spliceosome, a large ribonucleoprotein structure in which pre-mRNA splicing takes place.
What type of RNA is in a Snrnp?
The spliceosome is a large, protein-RNA complex that consists of five small nuclear RNAs (U1, U2, U4, U5, and U6) and over 150 proteins. The snRNAs, along with their associated proteins, form ribonucleoprotein complexes (snRNPs), which bind to specific sequences on the pre-mRNA substrate.
