Small Nucleolar RNA Snord103 (Paperback)

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. snoRNA U103 (also known as SNORD103) is a non-coding RNA (ncRNA) molecule which functions in the modification of other small nuclear RNAs (snRNAs). This type of modifiying 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 U103 belongs to the C/D box class of snoRNAs which contain the conserved sequence motifs known as the C box (UGAUGA) and the D box (CUGA). Most of the members of the box C/D family function in directing site-specific 2''-O-methylation of substrate RNAs.
