    • 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.

    • The characterization of LXR.alpha., an orphan member of the nuclear hormone receptor superfamily that can function as a tissue-specific mediator of 9-cis retinoic acid (9cRA) is described herein. When expressed in cells, LXR.alpha. activates transcription in response to 9cRA on a distinct response element, termed an LXRE. Significantly, neither RXR homodimers nor RXR/RAR heterodimers are able to substitute for LXR.alpha. in mediating this retinoid response. The LXR.alpha. response to retinoids is due to its unique interaction with endogenous RXR. This interaction shifts RXR from its previously described role as a silent, heterodimer partner to an active ligand binding partner, thus defining a novel retinoid response pathway.
    • 本文描述了可用作9-顺式视黄酸(9cRA)的组织特异性介质的核激素受体超家族的孤儿成员的LXRα的表征。 当在细胞中表达时,LXRα响应于9cRA在不同的响应元件(称为LXRE)上激活转录。 值得注意的是,RXR同源二聚体和RXR / RAR异源二聚体都不能在介导这种类视黄醇反应中替代LXRα。 对类维生素A的LXRα反应是由于其与内源性RXR的独特相互作用。 这种相互作用将RXR从其先前描述的作为静默的异二聚体配偶体的作用转移到活性配体结合配偶体,从而定义了新的维甲酸反应途径。
