From: The first identification of complete Eph-ephrin signalling in ctenophores and sponges reveals a role for neofunctionalization in the emergence of signalling domains

Fig. 2

Conserved domain architectures of Eph receptors in different holozoan lineages. a Schematic representation showing the presence (filled blue boxes) or absence (filled grey boxes) of full-length, partial and truncated Eph-receptor-like domain architectures in metazoans and unicellular holozoans. b Representative domain architectures of full length Eph receptors in non-bilaterian metazoans. Sequence identifies (numbers) are provided below the schematic domain architecture, and the actual protein sequences can be found in the Additional file 2
