The nuclear receptor coactivator 1 (NCOA1), also called steroid receptor coactivator-1 (SRC-1), is a transcriptional coregulatory protein that contains several nuclear receptor–interacting domains and possesses intrinsic histone acetyltransferase activity.^[5][6] It is encoded by the gene NCOA1.^[7]

NCOA1 is recruited to DNA promoter sites by ligand-activated nuclear receptors. NCOA1, in turn, acylates histones, which makes downstream DNA more accessible to transcription. Hence, NCOA1 assists nuclear receptors in the upregulation of DNA expression as a coactivator.^[5][6]
