Functions of signal transducers and activators of transcription (STAT) in the liver

  • 摘要:

    <正>1 JAK-STAT通路及其激活和调控1.1 JAK-STAT通路组成JAKs是一类胞浆内可溶性非受体酪氨酸蛋白激酶,分子量在120~140 kD左右。JAKs具有7个保守的同源结构域(JAK homology domain,JH)JH1~JH7。家族中已发现四个成员,即JAK1、JAK2、JAK3和Tyk2。JAKs的底物为STATs,即信号转导子和转录激活子(signal transduc-
