    Summary
    Predicted to enable growth factor activity and nerve growth factor receptor binding activity. Acts upstream of or within circadian behavior; multicellular organismal response to stress; and nervous system development. Predicted to be active in several cellular components, including axon; dendrite; and synaptic vesicle. Is expressed in several structures, including blastoderm; digestive system; kidney; nervous system; and oral region. Human ortholog(s) of this gene implicated in several diseases, including cocaine dependence; cognitive disorder (multiple); congenital central hypoventilation syndrome; neurodegenerative disease (multiple); and obstructive sleep apnea. Orthologous to human BDNF (brain derived neurotrophic factor). [provided by Alliance of Genome Resources, Dec 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.
