== Disease ==
[[http://www.uniprot.org/uniprot/NCOA1_HUMAN NCOA1_HUMAN]] Note=A chromosomal aberration involving NCOA1 is a cause of rhabdomyosarcoma. Translocation t(2;2)(q35;p23) with PAX3 generates the NCOA1-PAX3 oncogene consisting of the N-terminus part of PAX3 and the C-terminus part of NCOA1. The fusion protein acts as a transcriptional activator. Rhabdomyosarcoma is the most common soft tissue carcinoma in childhood, representing 5-8% of all malignancies in children. 
== Function ==
[[http://www.uniprot.org/uniprot/NR1H4_HUMAN NR1H4_HUMAN]] Ligand-activated transcription factor. Receptor for bile acids such as chenodeoxycholic acid, lithocholic acid and deoxycholic acid. Represses the transcription of the cholesterol 7-alpha-hydroxylase gene (CYP7A1) through the induction of NR0B2 or FGF19 expression, via two distinct mechanisms. Activates the intestinal bile acid-binding protein (IBABP). Activates the transcription of bile salt export pump ABCB11 by directly recruiting histone methyltransferase CARM1 to this locus.<ref>PMID:10334992</ref> <ref>PMID:10334993</ref> <ref>PMID:12815072</ref> <ref>PMID:15471871</ref> <ref>PMID:12718892</ref> <ref>PMID:18621523</ref> <ref>PMID:19410460</ref> <ref>PMID:19586769</ref>  [[http://www.uniprot.org/uniprot/NCOA1_HUMAN NCOA1_HUMAN]] Nuclear receptor coactivator that directly binds nuclear receptors and stimulates the transcriptional activities in a hormone-dependent fashion. Involved in the coactivation of different nuclear receptors, such as for steroids (PGR, GR and ER), retinoids (RXRs), thyroid hormone (TRs) and prostanoids (PPARs). Also involved in coactivation mediated by STAT3, STAT5A, STAT5B and STAT6 transcription factors. Displays histone acetyltransferase activity toward H3 and H4; the relevance of such activity remains however unclear. Plays a central role in creating multisubunit coactivator complexes that act via remodeling of chromatin, and possibly acts by participating in both chromatin remodeling and recruitment of general transcription factors. Required with NCOA2 to control energy balance between white and brown adipose tissues. Required for mediating steroid hormone response. Isoform 2 has a higher thyroid hormone-dependent transactivation activity than isoform 1 and isoform 3.<ref>PMID:9427757</ref> <ref>PMID:7481822</ref> <ref>PMID:9223431</ref> <ref>PMID:9296499</ref> <ref>PMID:9223281</ref> <ref>PMID:10449719</ref> <ref>PMID:12954634</ref>

== Publication Abstract from PubMed ==
Starting from the known FXR agonist GW 4064 1a, a series of stilbene replacements were prepared. The 6-substituted 1-naphthoic acid 1b was an equipotent FXR agonist with improved developability parameters relative to 1a. Analog 1b also reduced the severity of cholestasis in the ANIT acute cholestatic rat model.
