Visual pigments are the light-absorbing molecules that mediate vision. They consist of an apoprotein, opsin, covalently linked to cis-retinal. The three color pigments are found in the cone photoreceptor cells. Phosphorylated on some or all of the serine and threonine residues present in the C-terminal region. The disease is caused by variants affecting the gene represented in this entry. The disease is caused by variants affecting the gene represented in this entry.
