Comments
  • FUNCTION: Binds and transactivates the sequence 5'-TAATC[CA]-3' which is found upstream of several photoreceptor-specific genes, including the opsin genes. Essential for the maintenance of mammalian photoreceptors.
  • SUBUNIT: Interacts with SCA7 (By similarity). Interacts with RAX2.
  • SUBCELLULAR LOCATION: Nucleus (By similarity).
  • TISSUE SPECIFICITY: Retina.
  • DISEASE: Defects in CRX are a cause of Leber congenital amaurosis (LCA1) [MIM:204000, 602225]. LCA1 designates a clinically and genetically heterogeneous group of childhood retinal degenerations, generally inherited in an autosomal recessive manner. Affected infants have little or no retinal photoreceptor function as tested by electroretinography. LCA represents the most common genetic cause of congenital visual impairment in infants and children.
  • DISEASE: Defects in CRX are the cause of cone-rod dystrophy type 2 (CORD2) [MIM:120970]; also known as cone-rod retinal dystrophy 2 (CRD2). CORDs are inherited retinal dystrophies belonging to the group of pigmentary retinopathies. CORDs are characterized by retinal pigment deposits visible on fundus examination, predominantly in the macular region, and initial loss of cone photoreceptors followed by rod degeneration. This leads to decreased visual acuity and sensitivity in the central visual field, followed by loss of peripheral vision. Severe loss of vision occurs earlier than in retinitis pigmentosa.
  • DISEASE: Defects in CRX are a cause of retinitis pigmentosa (RP) [MIM:268000]. RP leads to degeneration of retinal photoreceptor cells. Patients typically have night vision blindness and loss of midperipheral visual field. As their condition progresses, they lose their far peripheral visual field and eventually central vision as well.
  • SIMILARITY: Belongs to the paired homeobox family.
  • SIMILARITY: Contains 1 homeobox DNA-binding domain.
  • WEB RESOURCE: Name=Mutations of the CRX gene; Note=Retina International's Scientific Newsletter; URL="http://www.retina-international.com/sci-news/crxmut.htm";.
  • WEB RESOURCE: Name=GeneReviews; URL="http://www.genetests.org/query?gene=CRX";.
