Abstract excerpt
Max is a basic helix-loop-helix/leucine zipper (bHLH/LZ) protein that forms sequence-specific DNA-binding complexes with the c-Myc oncoprotein (Myc). Using Saccharomyces cerevisiae, we have shown that the Max bHLH/LZ domain enables Myc to activate transcription through CACGTG and CACATG sequences in vivo, and that the number and context of such sites determines the level of activation. In addition, we have used...
