Preferred Name	Ribonucleoprotein, U4-U6 Small Nuclear
Definitions	A nuclear RNA-protein complex that plays a role in RNA processing. In the nucleoplasm, the U4-U6 snRNP along with the U5 snRNP preassemble into a single 25S particle that binds to the U1 and U2 snRNPs and the substrate to form mature SPLICEOSOMES. There is also evidence for the existence of individual U4 or U6 snRNPs in addition to their organization as a U4-U6 snRNP.
Synonyms	Small Nuclear Ribonucleoproteins, U4 Small Nuclear Ribonucleoproteins, U4 U6 Ribonucleoproteins, U6 Small Nuclear U4-U6 Small Nuclear Ribonucleoproteins U4 Small Nuclear Ribonucleoproteins U4 U6 Small Nuclear Ribonucleoproteins Ribonucleoproteins, Small, U4-U6 U4 snRNP U4-U6 snRNP Ribonucleoproteins, U4 Small Nuclear U6 snRNP Ribonucleoprotein, U4 U6 Small Nuclear Small Nuclear Ribonucleoproteins, U4-U6 U6 Small Nuclear Ribonucleoproteins Small Nuclear Ribonucleoproteins, U6 See more See less
