What's a GeneRIF?

The present study demonstrates an upregulatory effect of Phox2a and Phox2b on the expression of dopamine beta-hydroxylase and norepinephrine transporter in noradrenergic neurons of rat brains
Title: Transcription factor Phox2 upregulates expression of norepinephrine transporter and dopamine β-hydroxylase in adult rat brains.
mapped the distribution of Phox2a in the adult rat brain; data support the conclusion that Phox2a plays an important role in brainstem catecholamine neurotransmission and in the regulation of adaptive homeostatic functions in the adult nervous system
Title: Distribution and phenotype of Phox2a-containing neurons in the adult sprague-dawley rat.
Data show that exogenous Phox2a delivery to embryonic chick midbrain can drive a complete oculomotor complex molecular program, including the production of visceral and somatic motoneurons.
Title: PHOX2A regulation of oculomotor complex nucleogenesis.
data suggest that constitutive expression of Phox2a/2b defines the potential of neurons to become dopaminergic in response to membrane depolarization during a critical window of phenotypic plasticity.
Title: Expression of Phox2 transcription factors and induction of the dopaminergic phenotype in primary sensory neurons.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
