鸡卵清蛋白上游启动子转录因子(COUP-TF)是类固醇受体超家族的成员,参与多种基因的调控。尽管COUP-Tf具有多种功能,但尚未鉴定出配体或激活分子,因此它被归类为孤儿受体。瞬时转染实验中观察到生理浓度的神经递质多巴胺对COUP-TF的激活作用。用多巴胺受体激动剂α-麦角隐亭处理转基因细胞,也激活了报告基因依赖于Coup的表达。含有COOH-末端结构域缺失的COUP-Tf不被这些化合物激活。这些观察结果表明,多巴胺可能是COUP-TF的一种生理激活剂。
The chicken ovalbumin upstream promoter transcription factor (COUP-TF) is a member of the steroid receptor superfamily and participates in the regulation of several genes. While a number of functions have been ascribed to COUP-TF, no ligand or activator molecule has been identified, and thus it is classified as one of a group of orphan receptors. Activation of COUP-TF by physiological concentrations of the neurotransmitter dopamine was observed in transient transfection assays. Treatment of transfected cells with the dopamine receptor agonist alpha-ergocryptine also activated COUP-dependent expression of a reporter gene. COUP-TF that contained a deletion in the COOH-terminal domain was not activated by these compounds. These observations suggest that dopamine may be a physiological activator of COUP-TF.
