nuclear hormone receptor


Also found in: Encyclopedia.

nuclear hormone receptor

member of large family of intracellular molecules that act as ligand-activated transcription factors; all steroid and thyroid hormones and retinoic acid exert their effects through nuclear receptors. Member molecules that have no known ligand have been called orphan nuclear receptor.

DAX1

A gene (DSS-AHC critical region on the X chromosome, gene 1—formally known, per HUGO nomenclature, as NR0B1) located on chromosome Xp21.3 that encodes a protein containing a DNA-binding domain, which acts as a dominant-negative regulator of transcription mediated by the retinoic acid receptor. DAX1 also acts as an anti-testis gene by antagonising SRY.

Molecular pathology
DAX1 mutations cause both X-linked congenital adrenal hypoplasia and hypogonadotropic hypogonadism.
