Summary
(From RefSeq)
This gene product belongs to the nuclear receptor superfamily, members of which are transcription factors characterized by a ligand-binding domain and a DNA-binding domain. The encoded protein is a transcriptional regulator of the cytochrome P450 gene CYP3A4, binding to the response element of the CYP3A4 promoter as a heterodimer with the 9-cis retinoic acid receptor RXR. It is activated by a range of compounds that induce CYP3A4, including dexamethasone and rifampicin. Several alternatively spliced transcripts encoding different isoforms, some of which use non-AUG (CUG) translation initiation codon, have been described for this gene. Additional transcript variants exist, however, they have not been fully characterized. [provided by RefSeq, Jul 2008]
Function
(From Aceview)
There are�138 articles�specifically referring to this gene in PubMed. Functionally, the gene has been tested for association to�diseases�(Asthma; Breast Neoplasms; Coronary Artery Disease; Osteomalacia) and proposed to participate in a�process�(regulation of transcription, DNA-dependent). Proteins are expected to have molecular�functions�(metal ion binding, protein binding, sequence-specific DNA binding, steroid hormone receptor activity and�2 others) and to�localize�in various compartments (cytoplasm, nucleus). Putativeprotein interactors�have been described (ACTN2, NCOA1, NCOA3, NCOR2, NR1I2, NUCB2, POU1F1, PPARGC1A, PSMC5, RXRA, RXRB, RXRG, SRC).�

Human Isoforms
(From�Aceview)
The gene contains�12 distinct gt-ag introns. Transcription produces�9 different mRNAs, 7 alternatively spliced variants and 2 unspliced forms. There are 5 probablealternative promotors, 2 non overlapping alternative last exons and 4 validated�alternative polyadenylation sites�(see the�diagram). The mRNAs appear to differ by truncation of the 5' end, truncation of the 3' end, overlapping exons with different boundaries.�Efficacy of translation may be reduced by the presence of a shorter translated product (uORF) initiating at an AUG upstream of the main open reading frame (in variant dAug10).�
