Nkx2-9 Gene Summary [Mouse]
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).

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Nkx2-9 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
