Opsins are members of the guanine nucleotide-binding protein (G protein)-coupled receptor superfamily. OPN4 encodes a photoreceptive opsin protein melanopsin that is expressed within the ganglion and amacrine cell layers of the retina. In mouse, retinal ganglion cell axons expressing this gene projected to the suprachiasmatic nucleus and other brain nuclei involved in circadian photoentrainment. In mouse, this protein is coupled to a transient receptor potential (TRP) ion channel through a G protein signaling pathway and produces a physiologic light response via membrane depolarization and increased intracellular calcium. Melanopsin functions as a sensory photopigment and may also have photoisomerase activity. Experiments with knockout mice indicate that this gene attenuates, but does not abolish, photoentrainment. Alternative splicing results in multiple transcript variants encoding different isoforms.蛋白别名为：OPN4; MOP; Melanopsin; Opsin-4;基因ID为：94233；蛋白质ID:Q9UHM6
