Summary: Predicted to enable DNA-binding transcription factor activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Predicted to be involved in cell differentiation and regulation of transcription by RNA polymerase II. Predicted to be active in nucleus.

What's a GeneRIF?

Results suggest a role for NK1 homeobox 2 (NKX1-2) in promoting adipogenesis and possibly in regulating the balance between adipocyte and osteoblast differentiation of bone marrow mesenchymal precursor cells.
Title: The transcription factor NKX1-2 promotes adipogenesis and may contribute to a balance between adipocyte and osteoblast differentiation.
This study identifies Nkx1-2-expressing cells as the source of most trunk and tail tissues in the mouse.
Title: Lineage tracing of axial progenitors using Nkx1-2CreER(T2) mice defines their trunk and tail contributions.
In this study use a combination of genomics, CRISPR/Cas9 engineering and TF motif analysis to investigate the transcriptional networks guiding development of the MGE and its descendants. Whereas NKX2-1 is required for initiating MGE characteristics in the VZ.
Title: Genomic analysis of transcriptional networks directing progression of cell states during MGE development.
These results suggest that Nkx1-2 is a critical component of the gene regulatory network that operates downstream of Wnt/b-catenin signaling to regulate the formation of mesendoderm.
Title: Nkx1-2 is a transcriptional repressor and is essential for the activation of Brachyury in P19 mouse embryonal carcinoma cell.
In neurokinin 1 receptor knockout retinas no changes were seen: neurokinin 3 receptor mRNA levels as well as substance P and neurokinin 3 receptor immunostainings were similar to wild types.

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.
