Function Transcription factor that binds and transactivates the sequence 5'-TAATC[CA]-3' which is found upstream of several photoreceptor-specific genes, including the opsin genes. Acts synergistically with other transcription factors, such as NRL, RORB and RAX, to regulate photoreceptor cell-specific gene transcription. Essential for the maintenance of mammalian photoreceptors. {ECO:0000269PubMed:10625658}.
Subcellular Localization Nucleus {ECO:0000255PROSITE- ProRule:PRU00108}.
Disease Associations Leber congenital amaurosis 7 (LCA7) [MIM:613829]: A severe dystrophy of the retina, typically becoming evident in the first years of life. Visual function is usually poor and often accompanied by nystagmus, sluggish or near-absent pupillary responses, photophobia, high hyperopia and keratoconus. {ECO:0000269PubMed:20513135, ECO:0000269PubMed:9792858, ECO:0000269PubMed:9931337}. Note=The disease is caused by mutations affecting the gene represented in this entry.Cone-rod dystrophy 2 (CORD2) [MIM:120970]: An inherited retinal dystrophy 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. {ECO:0000269PubMed:9390563, ECO:0000269PubMed:9427255, ECO:0000269PubMed:9792858}. Note=The disease is caused by mutations affecting the gene represented in this entry.Retinitis pigmentosa (RP) [MIM:268000]: A retinal dystrophy belonging to the group of pigmentary retinopathies. Retinitis pigmentosa is characterized by retinal pigment deposits visible on fundus examination and primary loss of rod photoreceptor cells followed by secondary loss of cone photoreceptors. 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. {ECO:0000269PubMed:9427255, ECO:0000269PubMed:9792858}. Note=The disease is caused by mutations affecting the gene represented in this entry.
