Rhodopsin (RHO) Antibody – Mouse Monoclonal

Retinitis pigmentosa is an inherited progressive disease which is a major cause of blindness in western communities. It can be inherited as an autosomal dominant, autosomal recessive, or X-linked recessive disorder. In the autosomal dominant form,which comprises about 25% of total cases, approximately 30% of families have mutations in the gene encoding the rod photoreceptor-specific protein rhodopsin. This is the transmembrane protein which, when photoexcited, initiates the visual transduction cascade. Defects in this gene are also one of the causes of congenital stationary night blindness.

Rhodopsin: a G-protein coupled receptor. The light-absorbing visual pigment in Rod photoreceptor cells. Mediates vision in dim light. Consists of the apoprotein, opsin, covalently linked to cis-retinal. Defects in RHO are a cause of autosomal retinitis pigmentosa and congenital stationary night blindness.
