Uridine insertion/deletion RNA editing in kinetoplastid mitochondria involves the participation of a number of ribonucleoprotein complexes which contain multiple proteins. There are currently multiple names to designate the major editing complex and the polypeptide components, which has led to confusion and lack of communication both within and outside this field. We urge that the field adapt a more unified nomenclature for the complexes and the component polypeptides and we present possible options.
