NANOG Human Recombinant produced in E.coli is a single, non-glycosylated polypeptide chain containing 174 amino acids (1-154) and having a molecular mass of 19.6 kDa.The NANOG is fused to a 20 amino acid His-Tag at N-terminus and purified by proprietary chromatographic techniques.
NANOG is a multidomain homeobox transcription factor which functions to maintain the undifferentiated state of pluripotent stem cells. NANOG expression counteracts the differentiation-promoting signals induced by the extrinsic factors LIF, Stat3 and BMP. Once NANOG expression is downregulated, cell differentiation can proceed. Proteins which regulate NANOG expression include transcription factors Oct4, SOX2, FoxD3, and Tcf3 and tumor suppressor p53.
