This protein plays a critical role in pancreatic β cell function and proliferation. NKX6.1 is expressed in the nervous system during development and plays a key role in motor neuron specification. NKX6.1 also functions as an epithelial-to-mesenchymal transition suppressor, thereby suppressing the metastatic behavior of cancer cells according to literature."}]}]}
