Y_RNA

SO:0000405

Definition: Y RNAs are components of the Ro ribonucleoprotein particle (Ro RNP), in association with Ro60 and La proteins. The Y RNAs and Ro60 and La proteins are well conserved, but the function of the Ro RNP is not known. In humans the RNA component can be one of four small RNAs: hY1, hY3, hY4 and hY5. These small RNAs are predicted to fold into a conserved secondary structure containing three stem structures. The largest of the four, hY1, contains an additional hairpin.

Change history

This timeline summarizes changes identified in SO’s GitHub commit history, including updates to labels, definitions, parent terms, synonyms, subsets, and obsoletion status. It is a best-effort reconstruction and may not include every change to a term. Since only history from GitHub is included at the moment, any term added before the migration from SVN to Git will show as being created in 2016. This will be addressed once SVN history is incorporated.
