Description_x000D_ General description_x000D_ NLK (also known as nemo-like kinase) is a member of the serine/threonine protein kinase that is encoded by the NLK gene. NLK plays a role in cell fate determination and is required for the differentiation of bone marrow stromal cells. NLK also suppresses a wide range of transcription factors such as CREB by phosphorylation of the co-activator CREBBP. NLK expression increases the number of apoptotic cells but does not induce obvious cell cycle arrest. NLK suppresses Notch signalling by interfering with formation of the Notch active transcriptional complex._x000D_ Physical form_x000D_ Supplied in 50 mM Tris-HCl, pH 7.5, 150 mM NaCl, 10 mM glutathione, 0.1 mM EDTA, 0.25 mM DTT, 0.1 mM PMSF, 25% glycerol._x000D_ Preparation Note_x000D_ After opening, aliquot into smaller quantities and store at -70 °C.
