Recent insights into Groucho co-repressor recruitment and function

摘要

Gene expression is often controlled by transcriptional repressors during development. Many transcription factors lack intrinsic repressive activity but recruit co-factors that inhibit productive transcription. Here we discuss new insights and models for repression mediated by the Groucho/Transducin-Like Enhancer of split (Gro/TLE) family of co-repressor proteins.
