Mastermind-like protein 1 (MAML1)

Acts as a transcriptional coactivator for NOTCH proteins. Has been shown to Boost 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 in NOTCH enhancers and activates transcription.
