Menin

Function

Menin or multiple endocrine neoplasia I (Men) is a putative tumor suppressor. Men possesses two functional nuclear localization signals and inhibits transcriptional activation by JunD^[1].

Disease

Men mutations may be a common mechanism for inactivating tumor suppressor gene products in familial cancer^[2].
