IP Use at 1-4 µg/mg of lysate.


  • Function
    Acts as a transcriptional coactivator for NOTCH proteins. Has been shown to amplify NOTCH-induced transcription of HES1. Enhances phosphorylation and proteolytic turnover of the NOTCH intracellular domain in the nucleus through interaction with CDK8. Binds to CREBBP/CBP which promotes nucleosome acetylation at NOTCH enhancers and activates transcription. Induces phosphorylation and localization of CREBBP to nuclear foci. Plays a role in hematopoietic development by regulating NOTCH-mediated lymphoid cell fate decisions.
  • Tissue specificity
    Widely expressed with highest levels in heart, pancreas, peripheral blood leukocytes and spleen.
  • Sequence similarities
    Belongs to the mastermind family.
  • Domain
    The C-terminal region is required for transcriptional activation.
  • Cellular localization
    Nucleus speckle. Nuclear, in a punctate manner.
