Luke, G. and Holland, P.W. (1999) Amphioxus type I keratin cDNA and the evolution of intermediate filament genes. Journal of Experimental Zoology Part a-Comparative Experimental Biology, 285 (1). pp. 50-56. ISSN 0022-104X doi: 10.1002/(SICI)1097-010X(19990415)285:1<50::AID-JEZ6>3.0.CO;2-C
Abstract/Summary
We report the cloning of an intermediate filament (IF) cDNA from the cephalochordate amphioxus that encodes a protein assignable to the type I keratin group. This is the first type I keratin reported from an invertebrate. Molecular phylogenetic analyses reveal that amphioxus also possesses a type II keratin, and that the genes encoding short-rod IF proteins underwent different patterns of duplication in vertebrates and their closest relatives, the cephalochordates. Extensive IF gene duplication and divergence may have facilitated the origin of new specialised cell types in vertebrates.
