Keratins and Their Genes in Xenopus laevis
Cytokeratins and cytokeratin genes in Xenopus laevis have been studied from both a structural and a developmental point of view. The former must be seen in the context of the extensive work on cytokeratins in many vertebrate animals; the information obtained for Xenopus provides additional comparative opportunities with important evolutionary implications. Since most other studies on cytokeratins have been done on mammalian material, it is very useful to have extensive data available on a cold-blooded animal as well. The second major impetus for this work came from developmental considerations: cytokeratins are prominent tissue-specific products and the study of their expression proved to be a powerful tool for the characterization of developmental processes.
