Components of snrnps

WebSnRNPs "recognize" the places along a strand of pre-mRNA and are essential in the removal of introns. These molecules are found within the cell's nucleus. The two essential components of snRNPs are protein molecules and RNA. The RNA found within each snRNP particle is known as small nuclear RNA, or snRNA. WebSTRING analysis of nuclear eIF4E RIPs from LY1 cells indicates that eIF4E is physically associated with RNAs encoding components of each of the major snRNPs. Number of RNAs in each group is shown. All enrichments were statistically significant with false discovery rates (FDR) ranging from 0.0016 to 2.16 × 10 −49.
