WebJun 11, 2011 · Abstract. Melanocortin signalling is mediated by binding to a family of G protein-coupled receptors that positively couple to adenylyl cyclase. Tetrapod species have five melanocortin (MC –MC) receptors. The number of receptors varies in fish, zebrafish, for example, having six melanocortin receptors, with two copies of the melanocortin … WebCromatòfor. Els cromatòfors del peix zebra permeten el mimetisme amb el rerefons en ser exposats a ambients foscos (a dalt) o lluminosos (a baix). Els cromatòfors són cèl·lules amb pigments a l'interior que reflecteixen la llum. Poden trobar-se en diversos éssers vius, com els amfibis, els peixos, certs crustacis i alguns cefalòpodes.
