An unusual guide snoRNA U85 that functions in both 2′-O-ribose methylation and pseudouridylation of small nuclear RNA (snRNA) U5 has been identified. [14] This composite snoRNA contains both C/D and H/ACA box domains and associates with the proteins specific to each class of snoRNA (fibrillarin and Gar1p, respectively).
The second class, known as Lsm-class snRNA, consists of U6 and U6atac. Lsm-class snRNAs are transcribed by RNA polymerase III and never leave the nucleus, in contrast to Sm-class snRNA. Lsm-class snRNAs contain a 5′-γ-monomethylphosphate cap [ 6 ] and a 3′ stem–loop, terminating in a stretch of uridines that form the binding site for a ...
snRNA-seq uses isolated nuclei instead of the entire cells to profile gene expression. That is to say, scRNA-seq measures both cytoplasmic and nuclear transcripts, while snRNA-seq mainly measures nuclear transcripts (though some transcripts might be attached to the rough endoplasmic reticulum and partially preserved in nuclear preps).

In molecular biology, the small nucleolar RNA SNORA73 (also called U17/E1 RNA) belongs to the H/ACA class of small nucleolar RNAs (snoRNAs). SNORA73 has functions involved in mediating the formation of 18S rRNA (an essential component of the ribosome), [1] regulating chromatin function, [2] and facilitating secretion of proteins by directing specific mRNAs to the signal recognition particle ...
U6 snRNA is the non-coding small nuclear RNA (snRNA) component of U6 snRNP (small nuclear ribonucleoprotein), an RNA-protein complex that combines with other snRNPs, unmodified pre-mRNA, and various other proteins to assemble a spliceosome, a large RNA-protein molecular complex that catalyzes the excision of introns from pre-mRNA.
Among the things scientists have been looking at recently are the genetic differences of dogs living near in the Chernobyl Exclusion Zone (CEZ) near Pripyat in Ukraine, and a new study has been ...
This type of modifying RNA is usually located in the nucleolus of the eukaryotic cell which is a major site of snRNA biogenesis. It is known as a small nucleolar RNA (snoRNA) and also often referred to as a guide RNA. snoRNA snoR1 belongs to the C/D box class of snoRNAs which contain the conserved sequence motifs known as the C box (UGAUGA) and ...
