Also known as: Nkx6.3; 9130417I07Rik
Summary: Predicted to enable DNA-binding transcription activator activity, RNA polymerase II-specific; DNA-binding transcription repressor activity, RNA polymerase II-specific; and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Acts upstream of or within cell fate determination; enteroendocrine cell differentiation; and negative regulation of epithelial cell differentiation. Predicted to be active in nucleus. Is expressed in several structures, including central nervous system; ear; and gut. Orthologous to human NKX6-3 (NK6 homeobox 3). [provided by Alliance of Genome Resources, Nov 2024]
Expression: Biased expression in stomach adult (RPKM 8.8), duodenum adult (RPKM 7.3) and 2 other tissues See more

What's a GeneRIF?

Thus, cross-antagonism between Nkx6 and Ptf1a in multipotent progenitors governs the equilibrium between endocrine and acinar cell neogenesis required for normal pancreas development.
Title: Nkx6 transcription factors and Ptf1a function as antagonistic lineage determinants in multipotent pancreatic progenitors.
Nkx6.3 function is dispensable for CNS development and lead to the proposal that absence of overt defects is due to functional compensation from a related homeodomain transcription factor.
Title: Expression and function of Nkx6.3 in vertebrate hindbrain.
Nkx6.3 transcripts localize in the epithelium of the most distal stomach region, the antrum and pylorus; expression in the adult intestine is lower and confined to the proximal duodenum.
Title: Requirement of the tissue-restricted homeodomain transcription factor Nkx6.3 in differentiation of gastrin-producing G cells in the stomach antrum.
Nkx6.3 shows a remarkably selective expression in a subpopulation of differentiating V2 neurons at caudal hindbrain levels.

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.
