PHOX2A

Species
Homo sapiens
Symbol
PHOX2A
Name
paired like homeobox 2A
Synonyms
  • aristaless homeobox homolog
  • aristaless homeobox protein homolog
Biotype
protein coding gene
Automated Description
Enables DNA-binding transcription activator activity, RNA polymerase II-specific and RNA polymerase II transcription regulatory region sequence-specific DNA binding activity. Involved in positive regulation of transcription by RNA polymerase II. Acts upstream of or within regulation of transcription by RNA polymerase II. Located in chromatin. Implicated in congenital fibrosis of the extraocular muscles 2.
RGD Description
The protein encoded by this gene contains a paired-like homeodomain most similar to that of the Drosophila aristaless gene product. The encoded protein plays a central role in development of the autonomic nervous system. It regulates the expression of tyrosine hydroxylase and dopamine beta-hydroxylase, two catecholaminergic biosynthetic enzymes essential for the differentiation and maintenance of the noradrenergic neurotransmitter phenotype. The encoded protein has also been shown to regulate transcription of the alpha3 nicotinic acetylcholine receptor gene. Mutations in this gene have been associated with autosomal recessive congenital fibrosis of the extraocular muscles. [provided by RefSeq, Jul 2008]
