c-Myc (bHLHe39) is a transcription factor that regulates the expression of multiple genes involved in apoptosis, cell growth, differentiation, and proliferation. Active c-Myc is coupled to the MAX protein via c-Myc’s C-terminal helix-loop-helix leucine zipper (bHLHLZ) domain. The c-Myc-MAX heterodimer also interacts with a number of other transcription-related proteins including TRRAP, p107 and Miz-1, and c-Myc-MAX may indirectly regulate histone acetylases involved in chromatin remodeling. c-Myc is itself acetylated on lysine 323 by GCN5, and on lysine 148 and 157 by p300/CBP. The significance of c-Myc acetylation is still under investigation; however, previous studies have suggested that HAT-dependent acetylation of c-Myc may regulate its turnover and stability. c-Myc may play a role in various cancers such as Burkitt’s lymphoma.
