Gene: OPN5 
Alternate names for this Gene:  GPR136|GRP136|PGR12|TMEM13
Gene Summary: Opsins are members of the guanine nucleotide-binding protein (G protein)-coupled receptor superfamily. This opsin gene is expressed in the eye, brain, testes, and spinal cord. This gene belongs to the seven-exon subfamily of mammalian opsin genes that includes peropsin (RRH) and retinal G protein coupled receptor (RGR). Like these other seven-exon opsin genes, this family member may encode a protein with photoisomerase activity. Alternative splicing results in multiple transcript variants. 
Gene is located in Chromosome:  6
Location in Chromosome :  6p12.3
Description of this Gene:  opsin 5
Type of Gene:  protein-coding
