Abstract

HDART结合于HDAC(组蛋白脱乙酰基酶)并起到阻遏物的作用。同样，HDART直接结合于起核内受体共活化物作用的Skip，以抑制核内受体的转录。并且，HDART能结合于作为核内受体的转录共阻遏物之一的HDAC，由此强烈的抑制通过HDAC的组蛋白脱乙酰作用的转录。另一方面，获得了一种HDART的显性阴性肽，并证实该肽活化转录，与全长HDART蛋白作用相反。特别是，该肽在活化视黄酸受体转录的活性方面优于全反式视黄酸(ATRA)。

Description

参与转录调控的因子
技术领域
本发明涉及转录调控因子等等，更具体地，涉及能控制核激素受体引起的转录的因子或肽。
背景技术
激素，脂溶性维生素等在生物的稳定维持、能量代谢、分化、生长等方面起着重要的作用。这些激素的受体等是存在于核内的转录调控因子，并且与染色质DNA的特定位点结合从而控制基因的转录反应。在大多数情况下，当配体如激素等不与受体结合时，转录的发生将会受到抑制。一旦配体(如激素)与受体结合，转录将通过染色质结构的改变而活化。据报道，从核内受体到转录装置(transcriptor)的路程中，许多称作共活化物(co-activator)和共阻遏物(co-repressor)的因子形成复合体。配体未结合型受体与包含组蛋白脱乙酰基酶的共阻遏物结合，从而抑制基因表达。另一方面，当受体结构经过与配体的结合而发生变化时，共阻遏物复合体被释放，包含组蛋白乙酰基转移酶的共活化物复合体被募集(recruited)。比如Skip共活化物(即Ski相互作用蛋白，也称作N-CoA62)，它直接结合于某些类型的核内受体(比如维生素3受体，视黄酸受体，雌激素受体以及糖皮质激素受体)以增强由这些核内受体引起的基因表达(Baudino，T.A.，Kraichely，D.M.，Jefcoat，S.C.，Jr.，winchester，S.K.，Partridge，N.C.，and MacDonald，P.N.(1998)J.Biol Chem 273(26)，16434-41，MacDonaldo，P.N.，Baudio，T.A.，Tokumaru，H.，Dowd，D.R.，and Zhang，C.(2001)Streoids 66(3-5)，171-6)。发明内容
