Summary: Enables several functions, including DNA-binding transcription activator activity, RNA polymerase II-specific; RNA polymerase II cis-regulatory region sequence-specific DNA binding activity; and protein homodimerization activity. Involved in several processes, including cardiac muscle tissue development; regulation of heart contraction; and regulation of transcription by RNA polymerase II. Acts upstream of or within several processes, including circulatory system development; proepicardium development; and regulation of DNA-templated transcription. Located in cytoplasm and nucleus. Part of transcription regulator complex. Is expressed in several structures, including alimentary system; brain; branchial arch; heart; and hemolymphoid system. Used to study atrial heart septal defect 7; congenital heart disease; hypoplastic left heart syndrome; and tetralogy of Fallot. Human ortholog(s) of this gene implicated in aortic valve disease 2; atrioventricular block; congenital heart disease (multiple); and congenital nongoitrous hypothyroidism 5. Orthologous to human NKX2-5 (NK2 homeobox 5). [provided by Alliance of Genome Resources, Dec 2024]

Study shows that Nkx2-5 directly represses cardiac Furin expression. Furthermore, Furin is required for the maturation of the cardiac progenitor cells and for the correct formation of the atrioventricular junction where it is expressed. Finally, study shows that this function is, at least in part, mediated by modulation of the BMP pathway.

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.
