The length of an average snRNA is approximately 150 nucleotides. They are transcribed by either RNA polymerase II or RNA polymerase III. Their primary … Zobacz więcej snRNA are often divided into two classes based upon both common sequence features as well as associated protein factors such as the RNA-binding LSm proteins. The first class, … Zobacz więcej U1 snRNP is the initiator of spliceosomal activity in the cell by base pairing with the 5′ splice site of the pre-mRNA. In the major spliceosome, experimental data has shown that the U1 snRNP is present in equal stoichiometry with U2, U4, U5, and U6 snRNP. … Zobacz więcej In eukaryotes, snRNAs contain a significant amount of 2′-O-methylation modifications and pseudouridylations. These modifications are associated with snoRNA activity … Zobacz więcej Spliceosomes catalyse splicing, an integral step in eukaryotic precursor messenger RNA maturation. A splicing mistake in even a single nucleotide can be devastating to the cell, and … Zobacz więcej Through the study of small nuclear ribonucleoproteins (snRNPs) and small nucleolar (sno)RNPs we have been able to better understand many important diseases.
