Cadherins are distributed in metazoans. In vertebrates, the most common along with protocadherins are, the classical cadherins, type I and type II. In invertebrates, type III and IV ab cadherins. Here, we focused on the lepidopteran epithelial classical DE-cadherins because they function as a protein-like receptor of Bacillus thuringiensis Cry proteins. Alignment and blasting of protein sequences retrieved from NCBI and a phylogenetic tree was built. A common ancestor and several clades were formed among the different lepidopteran cadherins. The most common are Helicoverpa armigera and Spodoptera litura. Remarkably, lepidopteran cadherins (DE-Cad) from Spodoptera frugiperda (n = 20) matched human E-cadherins with an E value of 1.06 e-47 and a bit score of 177). This data indicate that genes that encode the classical cadherins, present in both, the epithelial midgut of lepidopterans (i.e. Spodoptera frugiperda) and/or the epithelial in mammals, are homologous (around 50%) in the N-terminal region ectodomains, including the conserved free-linkers calcium binding sites. This could have an impact in the diversity of the functionality of these proteins.
