NKX2.2 is a nuclear transcription factor to the NK2 homeobox 2 gene. This transcription factor is involved in neural morphogenesis as well as the development of neuroendocrine cells, such as those of pancreatic islet cells. The expression of NKX2.2 by IHC is a useful biomarker for distinguishing primitive neuroectodermal tumor/ Ewing sarcoma (PNET/ES) from other small blue round cell tumors, when used as a component of a panel of other tests.
