Light sensitivity in a vertebrate mechanoreceptor?

Baker, G. E., de Grip, W. J., Turton, M. , Wagner, H. J., Foster, R. G. & Douglas, R. H. (2015). Light sensitivity in a vertebrate mechanoreceptor?. The Journal of Experimental Biology, 218(18), pp. 2826-2829. doi: 10.1242/jeb.125203


Using immunohistochemistry and Western blot analysis we demonstrate that melanopsin is localised in cells around the central pore of lateral line neuromasts in the African clawed frog, Xenopus laevis. Since melanopsin is a known photoreceptor pigment with diverse functions in vertebrates, we suggest that the lateral line of Xenopus laevis, which is primarily a mechanorecptor, may also be light sensitive. Potential functions of such photosensitivity are discussed, including its role in mediating locomotor responses following dermal illumination.
