The role of small nuclear ribonucleoprotein particles in pre-mRNA splicing.
A small set of distinctive short RNA molecules are found in the nuclei of all higher eukaryotic cells and yeast, in protein complexes known as 'small nuclear ribonucleoprotein particles', or snRNPs. Recent work has confirmed early suggestions that these particles form part of the machinery by which primary RNA transcripts are processed to their mature, functional form. In particular, snRNPs have been shown to be an integral part of the 'spliceosome', a multi-component complex involved in the removal of intron sequences from the coding regions of messenger RNA precursors.
