Target Data

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.

  1. Our results showed that MEIS1 may have a negative role in regulation of MAML1expression during the esophageal squamous cell carcinoma progression. PMID: 28462489
  2. Authors report that p300 and CBP acetylate Mastermind-like 1 (Maml1) on amino acid residues K188 and K189 to recruit NACK to the Notch1 ternary complex, which results in the recruitment of RNA polymerase II to initiate transcription. PMID: 28625977
  3. Overexpression of Mastermind like1 was detected in 59% of tumor samples PMID: 28325367

  6. MMAL1 overexpression is associated with Esophageal Squamous Cell Carcinoma. PMID: 26294058
  7. study identifies that MAML1 is ubiquitinated in the absence of Notch signaling to maintain low levels of MAML1 in the cell PMID: 26225565
  8. In MCF-7 cells p53 associates with the Notch transcriptional complex (NTC) in a MAML1-dependent fashion, most likely through a p53-MAML1 interaction. PMID: 26033683
  9. The impact of MAML1 genetic variants to heart rate was discovered. PMID: 24680774
  10. Data indicate that EpCAM, CK19, and hMAM triple-marker-positive circulating tumor cells (CTCs) were detected in 86 of 98 (87.8 %) patients. PMID: 22990361
  11. Snail decreased transcription of Notch1 intracellular domain (NICD) target genes via competing with MAML1, co-activator, in NICD complex. PMID: 23454378
  12. Authors report that human papillomavirus type 8 E6 subverts NOTCH activation during keratinocyte differentiation by inhibiting RBPJ/MAML1 transcriptional activator complexes at NOTCH target DNA. PMID: 23365452
  13. This study demonstrated that targeting Maml1-induced tumor cell senescence and differentiation may alter the tumor microenvironment and cytokine and chemokine profiles and may also promote innate and adaptive immune cell infiltration and function. PMID: 22864395
  14. Bioinformatics assessment revealed a correlation between p300, EGR1 and MAML1 copy number and mRNA alterations in renal clear cell carcinoma and p300, EGR1 and MAML1 gene alterations were associated with increased overall survival. PMID: 23029358
  15. MAML1 is best known as the co-activator and effector of NOTCH-induced transcription, and BPV-1 E6 represses synthetic NOTCH-responsive promoters, endogenous NOTCH-responsive promoters, and is found in a complex with MAML1 in stably transformed cells PMID: 22249263

  28. MAML1 has a coactivator function for p53, independent of its function as a coactivator of Notch signaling pathway PMID: 17317671
  29. Maml1 participates in the Wnt signaling by modulating the beta-catenin/TCF activity. Maml1 is recruited by beta-catenin on the cyclin D1 and c-Myc promoters. Maml1 functions in the Wnt/beta-catenin pathway independently of Notch signaling. PMID: 17875709
