They share several motifs, mainly the seven transmembrane helices, GCPRs of the rhodopsin superfamily. All opsins bind a chromophore, such as 11-cis-retinal. The function of most opsins other than the photoisomerases is split into two steps: light absorption and G-protein activation. Photoisomerases, on the other hand, are not coupled to G-proteins - they are thought to generate and supply the chromophore that is used by visual opsins [1].

ZNRF-3 is a transmembrane E3 ubiquitin ligase that antagonizes Wnt signalling, the signalling system used to mediate Rspo protein actions. ZNFR3 and RNF43, alongside the Rspo proteins, have emerged as a system with therapeutic potential for a number of pathological processes. This domain is known as the ectodomain [1].
