It belongs to the NK class of homeodomain proteins and functions by regulating gene expression involved in cell fate determination and patterning during embryogenesis.\u003c\/p\u003e\u003cp\u003eZebrafish Nkx2.2a is one of two paralogs, the other being Nkx2.2b, resulting from a genome duplication event in teleosts. Nkx2.2a is considered a functional ortholog of the human NKX2 dash 2 gene. Both proteins are highly conserved and share similar developmental roles, particularly in the specification of ventral neural progenitors and in endocrine pancreas formation.\u003c\/p\u003e\u003cp\u003eIn zebrafish embryos, Nkx2.2a is expressed in the ventral neural tube, including the regions that give rise to motor neurons, oligodendrocyte precursors, and serotonergic neurons. It acts downstream of sonic hedgehog signaling and is essential for defining the identity of specific neuronal subtypes. Nkx2.2a also contributes to the early development of the pancreas, where it helps regulate differentiation of insulin producing beta cells and other endocrine cell types.\u003c\/p\u003e\u003cp\u003eLoss of Nkx2.2a function in zebrafish leads to defects in neuronal patterning and impaired endocrine pancreas development, mirroring the phenotypes observed in mammalian systems. Due to its conservation with the human NKX2 dash 2 gene and its involvement in key developmental processes, zebrafish Nkx2.2a is widely used as a model to study neurogenesis, pancreas biology, and transcriptional regulation in vertebrates.\u003c\/p\u003e","brand":"NSJ Bioreagents","offers":[{"title":"100 ug","offer_id":51549544415512,"sku":"RZ1250","price":539.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/files\/get_image_b0699869-c4dd-4558-ab3e-f237a47d9f0c.jpg?v=1768300673","url":"https:\/\/danabiosci.com\/products\/nsj-rz1250-100ug","provider":"Dana Bioscience","version":"1.0","type":"link"}
