    • The present invention relates to novel receptor polypeptides, which, upon interaction with certain ligands, or activation by certain compounds, modulate transcription of certain genes by binding to cognate response elements associated with promoters of such genes. The novel receptors of the invention modulate transcription in the presence of retinoid compounds.The receptors of the present invention differ significantly from known retinoic acid receptors, in protein primary sequence and in responsiveness to exposure to various retinoids.The invention provides DNAs encoding the novel receptors, expression vectors for expression of the receptors, cells transformed with such expression vectors, cells co-transformed with such expression vectors and with reporter vectors to monitor modulation of transcription by the receptors, and methods of using such co-transformed cells in screening for compounds which are capable, directly or indirectly, of activating the receptors.The invention also provides nucleic acid probes for identifying DNAs which encode additional retinoid receptors of the same class as the novel receptors disclosed herein.
    • 本发明涉及新的受体多肽,其在与某些配体相互作用或某些化合物的活化时,通过结合与这些基因的启动子相关的同源反应元件来调节某些基因的转录。 本发明的新受体在类视色素化合物存在下调节转录。 本发明的受体与已知的视黄酸受体显着不同,蛋白质一级序列和对各种类视黄醇的暴露反应。 本发明提供了编码新受体的DNA,用于表达受体的表达载体,用这种表达载体转化的细胞,用这些表达载体共转化的细胞和用报道载体监测受体转录的调节的方法 共转化细胞筛选能够直接或间接激活受体的化合物。 本发明还提供用于鉴定编码与本文公开的新型受体相同类别的另外的类视黄醇受体的DNA的核酸探针。
