ID:OPSG_HUMAN DESCRIPTION: RecName: Full=Medium-wave-sensitive opsin 1; AltName: Full=Green cone photoreceptor pigment; AltName: Full=Green-sensitive opsin; Short=GOP; FUNCTION: Visual pigments are the light-absorbing molecules that mediate vision. They consist of an apoprotein, opsin, covalently linked to cis-retinal. BIOPHYSICOCHEMICAL PROPERTIES: Absorption: Abs(max)=530 nm; SUBCELLULAR LOCATION: Membrane; Multi-pass membrane protein. TISSUE SPECIFICITY: The three color pigments are found in the cone photoreceptor cells. PTM: Phosphorylated on some or all of the serine and threonine residues present in the C-terminal region. DISEASE: Defects in OPN1MW are the cause of partial colorblindness deutan series (CBD) [MIM:303800]; also known as deuteranopia. DISEASE: Defects in OPN1MW are a cause of blue cone monochromacy (BCM) [MIM:303700]. A rare X-linked congenital stationary cone dysfunction syndrome characterized by the absence of functional long wavelength-sensitive and medium wavelength-sensitive cones in the retina. Color discrimination is severely impaired from birth, and vision is derived from the remaining preserved blue (S) cones and rod photoreceptors. BCM typically presents with reduced visual acuity, pendular nystagmus, and photophobia. Patients often have myopia. DISEASE: Defects in OPN1MW are a cause of cone dystrophy type 5 (COD5) [MIM:303700]. A X-linked cone dystrophy. Cone dystrophies are retinal dystrophies characterized by progressive degeneration of the cone photoreceptors with preservation of rod function, as indicated by electroretinogram. However, some rod involvement may be present in some cone dystrophies, particularly at late stage. Affected individuals suffer from photophobia, loss of visual acuity, color vision and central visual field. Another sign is the absence of macular lesions for many years. Cone dystrophies are distinguished from the cone-rod dystrophies in which some loss of peripheral vision also occurs. SIMILARITY: Belongs to the G-protein coupled receptor 1 family. Opsin subfamily.

The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
