Summary: Enables DNA-binding transcription activator activity, RNA polymerase II-specific and sequence-specific double-stranded DNA binding activity. Involved in several processes, including nervous system development; positive regulation of cold-induced thermogenesis; and regulation of respiratory gaseous exchange by nervous system process. Acts upstream of or within several processes, including negative regulation of type B pancreatic cell proliferation; nervous system development; and regulation of neuron differentiation. Located in nucleus. Is expressed in several structures, including adrenal gland; epibranchial placode; genitourinary system; gut; and nervous system. Used to study congenital central hypoventilation syndrome. Human ortholog(s) of this gene implicated in colorectal cancer; congenital central hypoventilation syndrome; and neuroblastoma. Orthologous to human PHOX2B (paired like homeobox 2B). [provided by Alliance of Genome Resources, Nov 2024]

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.
