Thus far, over 90 human peripherin/RDS gene mutations have been identified. 2020-08-18 · The PRPH2 gene (also known as RDS) provides instructions for making a protein called peripherin 2. This protein plays an important role in normal vision. Peripherin 2 is found in the retina, the light-sensitive tissue that lines the back of the eye.

Peripherin/rds is an integral membrane glycoprotein found in the rim regions of vertebrate photoreceptor cell discs. Natural mutations of the encoding gene result in degenerative retinal disorders, such as retinitis pigmentosa. As the peripherin/rds protein traffics up the transition zone to aid in the formation of new disks it has numerous binding partners, including a cargo sorting protein melanoregulin (MREG) as well as Calcium/Calmodulin (Ca/CaM) (Boesze-Battaglia, 2007; Edrington, 2007a). These functional and binding regions of peripherin/rds are illustrated in Fig.1. In this short communication we document the association of Ca/CaM with peripherin /rds, analyze its distribution profile in photoreceptor cells Conclusions: Mutations in the peripherin/RDS gene are the major cause of multifocal pattern dystrophy simulating STGD1/fundus flavimaculatus.

The relevance of this protein to photoreceptor outer segment morphology was first demonstrated in retinal degeneration slow ( rds) mice.

Papers; People; X-Shaped Macular Dystrophy with Flavimaculatus Flecks. Two families showed a retinal pigment epithelial dystrophy characterized by an X-shaped yellowish macular lesion … Abstract. Peripherin/rds, a transmembrane glycoprotein, has been localized to the rim region of mature disks and the basal region adjacent to the cilia of rod and cone outer segments where disk morphogenesis occurs (Arikawaet al.1992).The importance of peripherin/rds to photoreceptor outer segment structure is inferred by its involvement in theretinal degeneration slow (rds) mutant mouse … The Effect of Peripherin/rds Haploinsufﬁciency on Rod and Cone Photoreceptors Tong Cheng,1 Neal S.

In the family with ROM1 and RDS mutations, single heterozygotes were normal but 2002-05-01 This amino acid position in peripherin would thus be a key site of interest for study at the molecular level; to this purpose, the underlying pathogenic mechanisms have started to be explored.[19-21] A practical conclusion is that searching for RDS-ROM1 digenic causation in RP may not be worthwhile except when this codon 185 RDS mutation is detected in a family with RP.

Peripherin 2 (sometimes referred to as peripherin/RDS or simply RDS) is a cell surface glycoprotein found in the outer segment of both rod and cone photoreceptor cells. It is located in the rim regions of the flattened disks that contain rhodopsin , which is the protein that is responsible for initiation of visual phototransduction upon reception of light. The elaborate membranous architecture of the OS requires peripherin/rds (P/rds), an integral membrane protein and tetraspanin protein family member. Gene-level defects in P/rds cause a broad variety of late-onset progressive retinal degenerations in humans and dysmorphic photoreceptors in murine and Xenopus models. Previous studies indicate that the protein, peripherin or peripherin/rds, is localized along the rim of mature disks of rod outer segments. A mutation in the gene for this protein has been reported to be responsible for retinal degeneration in the rds mouse.

2001-07-01 · Introduction. Several mutations and polymorphisms of the peripherin/ RDS (retinal degeneration slow) gene have been found in patients with retinal dystrophies. 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14 Fujiki et al 13 have suggested that peripherin/ RDS gene mutations might be rare in Japanese patients.
