NCOR1（nuclear receptor corepressor 1），癌症关联基因，基因ID：9611，该基因编码一种蛋白质，通过促进染色质凝聚和阻止转录机制的进入，介导甲状腺激素和维甲酸受体的配体非依赖性转录抑制。它是一个复合物的一部分，该复合物还包括组蛋白脱乙酰酶和类似于酵母蛋白sin3p的转录调节因子，该基因位于17号染色体上charcot-marie-tooth和smith-magnis综合征的关键区域之间。交替剪接导致多个转录变体。在17号和20号染色体上发现了该基因的假基因。[由RefSeq提供，2010年6月]This gene encodes a protein that mediates ligand-independent transcription repression of thyroid-hormone and retinoic-acid receptors by promoting chromatin condensation and preventing access of the transcription machinery. It is part of a complex which also includes histone deacetylases and transcriptional regulators similar to the yeast protein Sin3p. This gene is located between the Charcot-Marie-Tooth and Smith-Magenis syndrome critical regions on chromosome 17. Alternate splicing results in multiple transcript variants. Pseudogenes of this gene are found on chromosomes 17 and 20.[provided by RefSeq， Jun 2010]。
