Involved in the negative feedback regulation of the light-activated signaling cascade in photoreceptors through a calcium-mediated process. Interacts with tetrapeptide ligand located in SLCterminal sequence of 3 key components of the visual cascade, tethering them and forming a macromolecular signaling phototransduction complex.
