MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] The DNA-associated protein encoded by this gene is a member of the paired family of homeobox proteins localized to the nucleus. The protein functions as a transcription factor involved in the development of several major noradrenergic neuron populations and the determination of neurotransmitter phenotype. The gene product is linked to enhancement of second messenger-mediated activation of the dopamine beta-hydroylase, c-fos promoters and several enhancers, including cyclic amp-response element and serum-response element. Expansion of a 20 amino acid polyalanine tract in this protein by 5-13 aa has been associated with congenital central hypoventilation syndrome. [provided by RefSeq, Jul 2016]
PHENOTYPE: Heterozygotes for an ethylnitrosourea-induced mutation exhibit dilated pupils and reduced preweaning viability. Other mice heterozygous for mutations in this gene exhibit respiratory failure and specific loss of parafacial interneurons. Homozygotes are inviable. [provided by MGI curators]
