BCAS3
Breast carcinoma amplified sequence 3, also known as BCAS3, is a protein which in humans is encoded by the ''BCAS3'' gene.〔(【引用サイトリンク】 url = http://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=54828 )〕 BCAS3 is a gene that is amplified and overexpressed in breast cancer cells.〔 == Function ==
The BCAS3 gene is regulated by estrogen receptor alpha (ER-α). The PELP1 protein acts as a transcriptional coactivator of estrogen receptor induced BCAS3 gene expression. In addition BCAS3 possesses histone acetyltransferase activity and itself appears to act as a coactivator of ER-α. Furthermore BCAS3 requires PELP1 to function as a coactivator in ER-α. Hence BCAS3 apparently is involved in a positive feedback loop leading to ER-α mediated signal amplification.〔
