Isolation of genes encoding the receptors for steroids, retinoids, vitamin D, and thyroid hormone and their structural and functional analysis revealed an evolutionarily conserved template for nuclear hormone receptors. This discovery sparked identification of numerous genes encoding related proteins, termed orphan receptors. Characterization of these orphan receptors and, in particular, of the retinoid X receptor (RXR) positioned nuclear receptors at the epicenter of the "Big Bang" of molecular endocrinology. This Review provides a personal perspective on nuclear receptors and explores their integrated and coordinated signaling networks that are essential for multicellular life, highlighting the RXR heterodimer and its associated ligands and transcriptional mechanism.
基因编码的甾体激素、维甲酸、维生素 D 和甲状腺激素受体的分离及其结构和功能分析揭示了核激素受体的一个进化保守模板。这一发现引发了对许多编码相关蛋白的基因的鉴定,这些蛋白被称为孤儿受体。这些孤儿受体的特征,特别是视黄酸 X 受体(RXR)的特征,将核受体置于分子内分泌学“大爆炸”的中心。本综述提供了核受体的个人观点,并探讨了它们的整合和协调的信号网络,这对多细胞生命是必不可少的,强调了 RXR 异二聚体及其相关配体和转录机制。
