COUP-TFICOUP-TF1 also known as NR2F1 is a protein that in humans is encoded by the NR2F1 gene. This protein is a member of nuclear hormone receptor family of steroid hormone receptors.FunctionCoup transcription factor binds to the ovalbumin promoter and, in conjunction with another protein stimulates initiation of transcription. COUP-TF1 binds to both direct repeats and palindromes of the 5'-AGGTCA-3' motif.InteractionsCOUP-TFI has been shown to interact with: BCL11A, BCL11B, COPS2, and ESR1.ClinicalMutations in this gene have been associated with Bosch-Boonstra-Schaaf optic atrophy syndrome.
