    NCoA-3 Antibody (4i301) is a mouse monoclonal IgG1 antibody that detects NCoA-3 in human samples through applications such as western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), and immunohistochemistry. NCoA-3, also known as RAC3, ACTR, AIB-1, and p/CIP, plays a crucial role as a transcriptional coactivator in the steroid receptor family, facilitating the transcriptional activation of hormone-responsive genes. NCoA-3 (4i301) antibody enables research into protein functions involving the regulation of gene expression in response to steroid hormones, thyroid hormones, and retinoic acids, which are vital for numerous physiological processes, including development, metabolism, and homeostasis. Notably, NCoA-3 is often overexpressed in estrogen receptor-positive ovarian and breast cancers, highlighting its importance in cancer biology and potential as a therapeutic target. The interaction of NCoA-3 with other proteins, such as p300/CBP, underscores its role in enhancing transcriptional activity, making anti-NCoA-3 antibody (4i301) a key tool for investigating the mechanisms of hormone signaling and cancer progression.
