U5 small nuclear ribonucleoproteins

Definitions of U5 Small Nuclear Ribonucleoproteins

  1. A nuclear RNA- protein complex that plays a role in RNA processing. In the nucleoplasm, the U5 snRNP along with U4- U6 snRNP preassemble into a single 25S particle that binds to the U1 and U2 snRNPs and the substrate to form SPLICEOSOMES.
