| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | Binding of FREAC-3 and FREAC-4 to their cognate sites results in bending of the DNA at an angle of 80-90 degrees. Regulates FOXO1 through binding to a conserved element, 5'-GTAAACAAA-3' in its promoter region, implicating FOXC1 as an important regulator of cell viability and resistance to oxidative stress in the eye. Ref.7 |
| Subunit structure | Monomer. Interacts with C1QBP. Ref.8 |
| Subcellular location | |
| Tissue specificity | Expressed in all tissues and cell lines examined. Ref.5 |
| Involvement in disease | Axenfeld-Rieger syndrome 3 (RIEG3) [MIM:602482]: An autosomal dominant disorder of morphogenesis that results in abnormal development of the anterior segment of the eye, and results in blindness from glaucoma in approximately 50% of affected individuals. Features include posterior corneal embryotoxon, prominent Schwalbe line and iris adhesion to the Schwalbe line, hypertelorism, hypodontia, sensorineural deafness, redundant periumbilical skin, and cardiovascular defects such as patent ductus arteriosus and atrial septal defect. When associated with tooth anomalies, the disorder is known as Rieger syndrome. Iridogoniodysgenesis anomaly (IGDA) [MIM:601631]: Autosomal dominant phenotype characterized by iris hypoplasia, goniodysgenesis, and juvenile glaucoma. Peters anomaly (PAN) [MIM:604229]: Consists of a central corneal leukoma, absence of the posterior corneal stroma and Descemet membrane, and a variable degree of iris and lenticular attachments to the central aspect of the posterior cornea. |
| Sequence similarities | Contains 1 fork-head DNA-binding domain. |
