The subcellular distribution of an RNA quality control protein, the Ro autoantigen, is regulated by noncoding Y RNA binding.


The Ro autoantigen is a ring-shaped RNA-binding protein that binds misfolded RNAs in nuclei and is proposed to function in quality control. In the cytoplasm, Ro binds noncoding RNAs, called Y RNAs, that inhibit access of Ro to other RNAs. Ro also assists survival of mammalian cells and at least one bacterium after UV irradiation. In mammals, Ro undergoes… (More)
