UniProt Annotation
Function Involved in the development of several major noradrenergic neuron populations, including the locus coeruleus. Transcription factor which could determine a neurotransmitter phenotype in vertebrates. Enhances second-messenger-mediated activation of the dopamine beta-hydrolase and c-fos promoters, and of several enhancers including cAMP-response element and serum- response element.
Subcellular Localization Nucleus {ECO:0000255PROSITE- ProRule:PRU00108}.
Disease Associations Congenital central hypoventilation syndrome (CCHS) [MIM:209880]: Rare disorder characterized by abnormal control of respiration in the absence of neuromuscular or lung disease, or an identifiable brain stem lesion. A deficiency in autonomic control of respiration results in inadequate or negligible ventilatory and arousal responses to hypercapnia and hypoxemia. {ECO:0000269PubMed:12640453, ECO:0000269PubMed:14566559, ECO:0000269PubMed:15657873}. Note=The disease is caused by mutations affecting the gene represented in this entry.Neuroblastoma 2 (NBLST2) [MIM:613013]: A common neoplasm of early childhood arising from embryonic cells that form the primitive neural crest and give rise to the adrenal medulla and the sympathetic nervous system. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.
Tissue Specificity Expressed in neuroblastoma, brain and adrenal gland.
