Coup (chicken ovalbumin upstream promoter) transcription factor binds to the ovalbumin promoter and, in conjunction with another protein (S300-II) stimulates initiation of transcription. Binds to both direct repeats and palindromes of the 5'-AGGTCA-3' motif. Represses transcriptional activity of LHCG. Binds DNA as dimer; homodimer and probable heterodimer with NR2F6 (PubMed:11682620). Interacts with GTF2B; this interaction is direct (PubMed:1517211). Interacts with COPS2 (PubMed:10207062). Inhibited by gonadotropin in granulosa cells. The disease is caused by variants affecting the gene represented in this entry. Belongs to the nuclear hormone receptor family. NR2 subfamily.
