This family of proteins is found in the photoreceptor cells of the retina [1,2]. Mutations of the gene encoding this protein have been associated with retinal disorders such as retinitis pigmentosa and late-onset progressive retinal atrophy [1-4]. The function of this family of proteins is unknown, but it is likely to be important in the development and function of the retina [2-3].
