The ultrastructural localization of 60-kDa Ro protein and human cytoplasmic RNAs: association with novel electron-dense bodies.
Genes for murine Y1 and Y3 Ro RNAs have class 3 RNA polymerase III promoter structures and are unlinked on mouse chromosome 6.
Y3 is the most conserved small RNA component of Ro ribonucleoprotein complexes in vertebrate species.
