Nuclear receptor coactivator 1

The nuclear receptor coactivator 1 is a transcriptional coregulatory protein that contains several is_associated_with::nuclear receptor interacting domains and an intrinsic is_associated_with::histone acetyltransferase activity. NCOA1 is recruited to DNA promotion sites by ligand-activated nuclear receptors. NCOA1, in turn, acylates histones, which makes downsteam DNA more accessible to transcription. Hence, NCOA1 assists nuclear receptors in the upregulation of DNA expression.

NCOA1 is also frequently called steroid receptor coactivator-1 (SRC-1).
