The nuclear receptor coactivator 3 also known as NCOA3 is a protein that, in humans, is encoded by the NCOA3 gene.[1][2] NCOA3 is also frequently called 'amplified in breast 1' (AIB1), steroid receptor coactivator-3 (SRC-3), or thyroid hormone receptor activator molecule 1 (TRAM-1).

Function[edit]

NCOA3 is a transcriptional coactivator protein that contains several nuclear receptor interacting domains and an intrinsic histone acetyltransferase activity. NCOA3 is recruited to DNA promotion sites by ligand-activated nuclear receptors. NCOA3, in turn, acylates histones, which makes downstream DNA more accessible to transcription. Hence, NCOA3 assists nuclear receptors in the upregulation of gene expression.[3][4]

Clinical significance[edit]

The ratio of PAX2 to AIB-1 protein expression may be predictive of the effectiveness of tamoxifen in breast cancer treatment.[5][6]
