Abstract
The melanoma antigen (MAGE) protein family contains more than 25 members that share a conserved MAGE homology domain (MHD). Type I MAGE genes exhibit cancer/testis-specific expression patterns and antigenic properties which render them ideal candidates for cancer immunotherapies. Maged1, a type II MAGE gene, is ubiquitously expressed and has been previously shown to play an important role in neuronal apoptosis during development. Recent studies have expanded the functional tissues and processes in which Maged1 activity is important and uncovered interacting partners of MAGED1 protein, adding novel layers to Maged1 functions. Maged1 plays a role in anti-tumorigenesis in a variety of cell types, and the down-regulation of MAGED1 has been observed in tumor cells. Moreover, MAGED1 can interact with a specific group of nuclear members and regulate circadian clock functions. These newly identified functions will enrich the molecular and clinical studies of the MAGE family of proteins.
