dc.description.abstract The homologous membrane proteins Rom-1 and peripherin-2 are localized to the disk rims of photoreceptor outer segments (OSs), where they associate as tetramers and larger oligomers1, 2, 3. Disk rims are thought to be critical for disk morphogenesis, OS renewal4 and the maintenance of OS structure5, but the molecules which regulate these processes are unknown. Although peripherin-2 is known to be required for OS formation (because Prph2−/− mice do not form OSs; ref. 6), and mutations in RDS (the human homologue of Prph2) cause retinal degeneration7, the relationship of Rom-1 to these processes is uncertain. Here we show that Rom1−/− mice form OSs in which peripherin-2 homotetramers are localized to the disk rims, indicating that peripherin-2 alone is sufficient for both disk and OS morphogenesis. The disks produced in Rom1−/− mice were large, rod OSs were highly disorganized (a phenotype which largely normalized with age) and rod photoreceptors died slowly by apoptosis. Furthermore, the maximal photoresponse of Rom1−/− rod photoreceptors was lower than that of controls. We conclude that Rom-1 is required for the regulation of disk morphogenesis and the viability of mammalian rod photoreceptors, and that mutations in human ROM1 may cause recessive photoreceptor degeneration. hu
