Anti-NKX6.2 from rabbit, purified by affinity chromatography

Homeobox protein Nkx-6.2 (UniProt Q9C056; also known as Homeobox protein NK-6 homolog B) is encoded by the NKX6-2 (also known as GTX, NKX6B) gene (Gene ID 84504) in human. Mammalian NKX gene products and their orthologs in other species are known to regulators of neuronal cell fate. Both the ventral nervous system defective (vnd) gene product in Drosophila and murine NKX proteins in spinal cord direct progenitors to adopt specific ventral neural identities. In mice, NKX6.2 is expressed in a small subset of ventral neural progenitors in a restricted spatial pattern at the border between the medial and caudal ganglionic eminence (MGE and CGE). NKX6,2 is required for specification of V1 interneurons in the spinal cord and progenitors are found to adopt a more dorsal V0 identity in the absence of NKX6,2. In addition, NKX6.2-positive brain region is shown to give rise to both parvalbumin (PV) and somatostatin (SST) cortical interneurons and in particular be enriched in a subpopulation of SST cortical interneurons that coexpress calretinin (CR).
