| Heterodimerization with RXR in solution is still a controversial issue. However, COUP-TFs readily form DNA-binding heterodimers with RXR. COUP-TFI is able to heterodimerize with COUP-TFII. Systematic comparison of the relative affinities of COUP-TFs for the various elements reveal that DR1 is the preferred element and then DR6, DR4, DR8, DR0 and DR11. Palindromic and inverted repeats are also recognised but with a lower affinity. In contrast, monomeric elements are not efficiently recognised by COUP-TFs. It has been demonstrated that COUP-TFs repress the hormonal induction of target genes by PPAR, VDR, TR, and RAR in transient transfection assays through direct competition with VDR, TR, and RAR for the available binding sites. | |||||||
| Co-binding Partners |
|||
| Name | Interaction | Effect | Reference |
| Retinoid X receptor-β | Physical, Functional | COUP-TFs are able to sequester the common heterodimerization partner RXR and reduce the available concentrations of RXR. The loss of RXR indirectly decreases the DNA-binding affinity of TR, VDR, RAR, and PPAR and thereby interferes with the potential of this subgroup of receptors to transactivate their target genes. | 7-8,10,31 |
| Hepatocyte nuclear factor-4-α | Physical, Functional | COUP-TF interact both functionally and physically with the NRs HNF4. COUP-TFs have been shown to inhibit the transactivation of HNF4 due to mutually exclusive binding to the promoter of many genes. In addition, COUP-TF activates transcription through protein-protein interaction with DNA-bound factor, such as with HNF-4 in the HNF-1a gene promoter. Similar mechanism are observed for other transcription factor (Sp1). | 11,24,28 |
| Thyroid hormone receptor-α | Physical, Functional | COUP-TFs:TR heterodimerization interfere with TR dependent transcriptional regulation. | 7,12 |
| Retinoic acid receptor-α | Physical, Functional | COUP-TFs:RAR heterodimerization interfere with RAR dependent transcriptional regulation. | 7,12 |
| Estrogen receptor-α | Physical, Functional | the formation of a tight ERa-COUP-TFI intermediate complex through COUP-TFI DBD and ER LBD resulted in an increased recruitment of ERK2/p42 MAPK, phosphorylation of the hERa on Ser 118 and enhanced its transcriptional activity. In addition, COUP-TF has been shown to antagonize ER activation of the lactoferrin and oxytocin promoters by binding to a binding site that overlaps with the estrogen response element. | 14,17 |
| BCL11A | Physical, Functional | COUP-TFs ligand binding domain interacts with BCL11A to repress its endogenous target γ-globin nand Bgl3 genes | 3,5 |

| Tissue Distribution Comments | |
| In human COUP-TFI is expressed as two transcripts of 4.6 and 4.8 kb that show a broad expression pattern. In mice, COUP-TFI expression was first detected at 7.5 dpc, peaked at 14-15 days dpc and strongly declined before birth when organogenesis stops. At 8.5 dpc COUP-TFI is expressed in specific regions of the rostral brain, in stripes in the presumptive hindbrain as well as in the anterior somites. Later on, it exhibits a more complex expression pattern in CNS which is clearly different from the one of COUP-TFII. COUP-TFI is expressed throughout the neural tube with a small increased level in motoneurons. The expression appears also restricted in other organs and is always weaker than the one of COUP-TFII. COUP-TFI is found at high levels in the tongue, the follicles of the vibrissae, the cochlea and in the nasal septum stroma. In organs that requires mesenchymal and epithelial interactions, COUP-TFI is expressed in the mesenchymal cells, but not in the terminally differentiated epithelium. In adult, the expression is strongly reduced and COUP-TFI was found in the rostral and caudal part of the mouse brain, in particular in the supraoptic nucleus [3,20-21]. |

| These animals exhibit defects in morphogenesis of the ninth cranial ganglion and nerve resulting from an excess cell death in the ganglionic precursor cells. In addition axonal guidance and arborization defects were noticed in several regions. This results in a fewer number of cells in the ninth ganglia and abnormal nerve projections toward the hindbrain. Since the ninth ganglia supplies sensory and motor innervation to the pharynx and root of the tongue as well as to the ear and soft palate this may explain the inability of the mutant animals to obtain exogenous nutriments and there death by starvation and dehydratation. In addition COUP-TFI mutants have axon guidance defect which results in the thanlamocortical axon could not reach cortex to innervate neurons in layer IV and to maintain layer IV neuron survival. Furthermore, COUP-TFI mutants has brain regionalization defect. COUP-TFI is one of the regulatory genes that control the expression of genes important for brain regionalization. Finally, COUP-TFI is important for axon myelination. Without it oligodendrocytes cannot differentiation properly. Numerous studies over past decades unequivocally demonstrate that COUP-TFs are key players dictating the development of neural stem/progenitor cells (NSPC) at various subareas of central nervous system (CNS). First, COUP-TFs are intrinsic factors defining the competence of NSPCs and COUP-TFs are required for the gliogenic competence and neuropotency of neural precursor cells in the CNS development [18]. Second, COUP-TFI gene determines the spatial specification of NSPC as COUP-TFI controls the early neocortical regionalization [36]. Further analyses using the dorsal telencephalon specific COUP-TFI knockout indicate that COUP-TFI is necessary for the cortical patterning between frontal/motor and sensory areas [2]. COUP-TFs also define diverse cell fates during NSPCs development. In Emx1Cre mediated COUP-TFI-deficient mice, the corticospinal motor neurons in the somatosensory cortex do not develop properly [30]. Another mutant mouse, having COUP-TFI depleted in the subventricular precursors and postmitotic cells, shows a decrease in late-born, caudal ganglionic eminence (CGE)-derived cortical interneuons with the concomitant augment of early-born cortical interneurons originated from medial ganglionic eminence (MGE) [15]. In addition, COUP-TFI and COUP-TFII coordinately modulates the proliferation, migration and survival of granule cells in the olfactory bulb [37]. Moreover, COUP-TF transcriptional factors are present in dorsal or ventral retinal neural stem cells and direct appropriate neural retina development [23,29]. |
