Species Distribution
Presumptive Y RNA and Ro protein homologs have been found in eukaryotes and bacteria. Humans appear to have four Y RNAs, named hY1, hY3, hY4 and hY5 and also a large number of pseudogenes. C. elegans has one, named CeY RNA and a large number of sbRNAs that are postulated to also be Y RNA homologues. The radiation-resistant bacterium Deinococcus radiodurans encodes a homolog of Ro called rsr ("Ro sixty related"), and at least four small RNAs accumulate in Deinococcus under conditions where rsr expression is induced (UV irradiation); one of these RNAs appears to be a Y RNA homolog.

Famous quotes containing the words species and/or distribution:
“A man can go from being a lover to being a stranger in three moves flat ... but a woman under the guise of friendship will engage in acts of duplicity which come to light very much later. There are different species of self-justification.”
—Anita Brookner (b. 1938)
“In this distribution of functions, the scholar is the delegated intellect. In the right state, he is, Man Thinking. In the degenerate state, when the victim of society, he tends to become a mere thinker, or, still worse, the parrot of other men’s thinking.”
—Ralph Waldo Emerson (1803–1882)
