NCIt definition : A fusion protein (1024 aa, 112 kDa) encoded by the CRTC1/MAML2 fusion gene. This
protein is comprised of the first 42 N-terminal amino acids of the CREB-regulated
transcription coactivator 1 protein fused to most of the mastermind-like protein 2.;
NCIt note : The CRTC1/MAML2 fusion protein activates transcription of the Notch target gene HES1
independently of both Notch ligand and CSL. (Atlas of Genetics and Cytogenetics in
