SRC-1

Introduction

The nuclear receptor coactivator 1 (NCOA1) is a transcriptional coregulatory protein that contains several nuclear receptor interacting domains and an intrinsic histone acetyltransferase activity (EC 2.3.1.48). NCOA1 is recruited to DNA promotion 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.[1][2]

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

Interactions

Interactions

Nuclear receptor coactivator 1 possesses a basic helix-loop-helix (bHLH) domain and has been shown to interact with:
