Abstract

Introns are found in the nucleus, in bacteria, in phages and in organelles. All known organellar introns can be classified into two distinct classes according to their structures and splicing pathways: group-I and group-II introns. However, it has to be noted that the distributions of both classes are not limited to organellar genomes. Both classes contain self-splicing introns. Furthermore, some of the introns are mobile. Group-II introns are remarkable because their splicing mechanism resembles that of nuclear pre-messenger RNA (mRNA) introns and because of their much more complex mobility pathway than group-I introns. Also, in contrast to group-I introns, the mobility of group-II introns is strongly linked to their biological role as introns (i.e., splicing). Here, we review recent findings regarding the splicing, distribution and mobility of group-II introns.
