Also known as: Nkx2-8; Nkx2.9; tinman; Nkx-2.9
Summary: Predicted to enable DNA-binding transcription activator activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Acts upstream of or within axonogenesis; lung development; and negative regulation of epithelial cell proliferation. Predicted to be active in nucleus. Is expressed in several structures, including central nervous system; embryo ectoderm; embryo mesoderm; liver; and lung epithelium. Orthologous to human NKX2-8 (NK2 homeobox 8).

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.
