Definitions of U2 snRNP

  1.   A nuclear RNA protein complex that plays a role in RNA processing In the nucleoplasm the U2 snRNP along with other small nuclear ribonucleoproteins U1 U4 U6 and U5 assemble into SPLICEOSOMES that remove introns from pre mRNA by splicing The U2 snRNA forms base pairs with conserved sequence motifs at the branch point which associates with a heat and RNAase sensitive factor in an early step of splicing
