Folliculin
Folliculin also known as FLCN, BHD, FLCL, FLCN_HUMAN, MGC17998, or MGC23445 is a protein associated with Birt-Hogg-Dubé syndrome. It is encoded by the Folliculin gene sometimes also referred to as the BHD gene.
The function of the folliculin protein has yet to be determined but current research suggests it may act as a tumor suppressor. Tumor suppressors help control the growth and division of cells.
