Summary: Enables several functions, including DNA-binding transcription factor activity; histone deacetylase binding activity; and identical protein binding activity. Involved in several processes, including cellular response to hydrogen peroxide; negative regulation of transcription by RNA polymerase II; and response to estradiol. Predicted to be located in cytoplasm. Predicted to be part of Nkx-2.5 complex and protein-DNA complex. Predicted to be active in nucleus. Biomarker of pulmonary fibrosis. 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]

The authors findings suggest that Nkx2.5, as a transcription factor, may be a regulatory element connecting different signaling pathways in response to oxidative stress and that reduced Nsd1 (Nuclear receptor-binding SET domain-containing protein 1) expression could lead to the alteration of global H3K36 and H4K20 methylation, influencing cardiac development.

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.
