Clemen, * Vasily Rybakin and Ludwig Eichinger he coronins, first described in Dictyostelium discoideum in 1991, have meanwhile been detected in all eukaryotes except plants. They belong to the superfamily of WD40-repeat Tproteins and represent a large family of proteins, which are often involved in cytoskeletal functions. Phylogenetic studies clearly distinguish 12 subfamilies of which six exclusively occur in vertebrates.
