Chicken ovalbumin upstream promoter transcription factors (COUP-TFs) belong to the steroid/thyroid hormone receptor superfamily. Cloning of their cDNAs demonstrated the existence of two distinct but related genes: COUP-TFI (EAR-3, NR2F1) and COUP-TFII (ARP-1, NR2F2). They are referred to as orphan receptors because ligands for COUP-TFs have yet to be identified. Since 1998, extensive studies have demonstrated their physiological importance in cell-fate specification, organogenesis, angiogenesis, and metabolism, as well as a variety of diseases. In this article, we will comprehensively review the biological functions of COUP-TFII and its underlying mechanism in various developmental processes and diseases. In addition, we will briefly summarize some of the current findings of COUP-TFI.
鸡卵清蛋白上游启动子转录因子(COUP-TFs)属于甾体/甲状腺激素受体超家族。它们的 cDNA 克隆表明存在两种不同但相关的基因:COUP-TFI(EAR-3,NR2F1)和 COUP-TFII(ARP-1,NR2F2)。它们被称为孤儿受体,因为 COUP-TFs 的配体尚未被确定。自 1998 年以来,广泛的研究已经证明了它们在细胞命运特化、器官发生、血管生成和代谢以及各种疾病中的生理重要性。在本文中,我们将全面综述 COUP-TFII 的生物学功能及其在各种发育过程和疾病中的潜在机制。此外,我们将简要总结 COUP-TFI 的一些最新发现。
