What is the official name of the MEN1 gene?
The official name of this gene is “multiple endocrine neoplasia I.”
MEN1 is the gene's official symbol. The MEN1 gene is also known by other names, listed below.

What is the normal function of the MEN1 gene?
The MEN1 gene provides instructions for making a protein called menin. This protein acts as a tumor suppressor, which means that it keeps cells from growing and dividing too fast or in an uncontrolled way. Although the exact function of menin is uncertain, it is likely involved in several important cell functions. For example, it may play a role in copying and repairing DNA and regulating controlled cell death (apoptosis). The menin protein is present in the nucleus of many different types of cells and appears to be active in all stages of development.
Menin interacts with many other proteins, including several transcription factors. Transcription factors bind to specific areas of DNA and help control whether particular genes are turned on or off. Some of these genes likely play a role in cell growth and division. Researchers are working to identify the proteins that interact with menin and determine its specific role as a tumor suppressor.
