How transcription factors (TFs) control enhancer and promoter functions to effect changes in gene expression is an important question. In this issue, Hau et al. (2017. https://doi.org/10.1083/jcb.201701154) show that the TALE TF MEIS recruits the histone modifier PARP1/ARTD1 at promoters to decompact chromatin and activate transcription.
转录因子(TFs)如何控制增强子和启动子功能以实现基因表达的变化是一个重要问题。在本期中,豪等人(2017年。https://doi.org/10.1083/jcb.201701154)表明,TALE转录因子MEIS在启动子处募集组蛋白修饰因子PARP1/ARTD1,以松解染色质并激活转录。
