| Abstract: | The catalogue of mosaic proteins showing evidence of exon-shuffling continues to expand. The repeated use of exon modules suggests that current protein diversity could have been generated from a finite set of such exon modules, and that the size and character of this underlying exon universe can still be glimpsed in extant proteins. |
