Cone-rod homeobox protein is a protein that in humans is encoded by the CRX gene.The protein encoded by this gene is a photoreceptor-specific transcription factor which plays a role in the differentiation of photoreceptor cells. This homeodomain protein is necessary for the maintenance of normal cone and rod function. Mutations in this gene are associated with photoreceptor degeneration Leber congenital amaurosis type III and the autosomal dominant cone-rod dystrophy 2.
