简介:神经元限制性沉默因子(neuron-restrictivesilencerfactor,NRSF),是一种重要的锌指蛋白转录负调控因子,它与某些基因中相应的神经元限制性沉默元件(neuronrestrictivesilencerelement,NRSE),又称RE-1(repressorelement1,RE-1)相结合,从而对许多与神经元发育及功能相关的基因的表达发挥阻遏作用。REST辅助抑制因子(RESTcorepressor,CoREST)是一种神经元表型调控因子,CoREST与REST的C端结构域(含有一个C2H2型锌指结构)结合,形成阻遏复合物,发挥转录抑制作用。本文就REST和CoREST在神经发育过程中的调控作用进行综述。
