Retinitis pigmentosa (RP) is a blinding retinal disease in which the photoreceptor cells
degenerate. Mutations in the gene for retinitis pigmentosa GTPase regulator (RPGR) are a
frequent cause of RP. The function of RPGR is not well understood, but it is thought to be a
putative guanine nucleotide exchange factor for an unknown G protein. Ablation of the
RPGR gene in mice suggested a role in maintaining the polarized distribution of opsin
across the cilia. To investigate its function, we used a protein interaction screen to identify …
