Menin Antibody

The MEN1 gene encodes Menin, a nuclear scaffold protein that regulates gene transcription by coordinating chromatin remodeling. It is mapped to 11q13.1. MEN1 is considered to act as a tumor suppressor gene. It has been found that that MEN1 inactivation by antisense RNA antagonizes transforming growth factor-beta-mediated cell growth inhibition. Overexpression in an inducible cell culture system downregulated the proximal promoter. In vitro studies have shown that the protein is localized to the nucleus, possesses two functional nuclear localization signals, and inhibits transcriptional activation by JunD. Additionally, MEN1 was essential to maintain MLL-associated myeloid transformation.
