Summary: Enables chromatin binding activity and transcription cis-regulatory region binding activity. Acts upstream of or within with a positive effect on neural crest cell migration. Acts upstream of or within several processes, including hematopoietic stem cell differentiation; macrophage migration; and motor neuron axon guidance. Predicted to be located in cytoplasm and nucleus. Is expressed in several structures, including cardiovascular system; digestive system; musculature system; nervous system; and pleuroperitoneal region. Human ortholog(s) of this gene implicated in carcinoma (multiple); diabetic retinopathy; myocardial infarction; prostate cancer; and type 2 diabetes mellitus. Orthologous to human HIF1A (hypoxia inducible factor 1 subunit alpha). [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.
