مستخلص: | The genomic structure of the mouse 59-kDa keratin gene, a Type I intermediate filament (IF) gene is presented. A comparison of the organization of this gene with that of the human 67-kDa keratin, a Type II IF gene, and hamster vimentin, a Type III IF gene, suggests a common evolutionary origin for Type I, II, and III IF genes. Most introns in these three types of IF genes occur at similar positions within the region encoding sequences predicted to form coiled-coils, but do not delineate structural subdomains. Interestingly though, most of the introns interrupt at or near the beginning of the characteristic 7-residue (heptad) repeat of sequences which form the coiled-coil. These data suggest that the three types of IF genes arose from a common ancestor which may have been assembled from smaller units containing multiple heptad repeats. Subsequent duplication events may then have formed the three known alpha-helical types and each of their various members. |
