Menin: Expanding and dichotomous roles in cancer

Abstract

Menin, the protein product of the MEN1 gene, is a ubiquitously expressed protein that lacks homology with other protein families, yet is highly conserved among various species [1]. Menin primarily resides in the nucleus, where it serves as a scaffold for epigenetic regulators [1, 2]. While much is known about menin and its diverse roles in numerous cellular processes, there remains much to be discovered, especially with regard to its role in cancer.
