Protein-coding gene in the species Homo sapiens
Mastermind-like protein 1 is a
protein that in humans is encoded by the MAML1
gene .
[5]
[6]
[7]
Function
This protein is the human homolog of mastermind, a Drosophila protein that plays a role in the Notch signaling pathway involved in cell-fate determination. There is in vitro evidence that the human homolog forms a complex with the intracellular portion of human Notch receptors and can increase expression of a Notch-induced gene. This evidence supports its proposed function as a transcriptional co-activator in the Notch signaling pathway.
