The nuclear receptor co-repressor 1 also known as thyroid-hormone- and retinoic-acid-receptor-associated co-repressor 1 (TRAC-1) is a protein that in humans is encoded by the NCOR1 gene.

NCOR1 is a transcriptional coregulatory protein which contains several nuclear receptor interacting domains. In addition, NCOR1 appears to recruit histone deacetylases to DNA promoter regions. Hence NCOR1 assists nuclear receptors in the downregulation of gene expression.

Loss of function of this protein significantly increases the strength and power of mouse muscles.
