The Max protein forms a heterodimeric complex with the Myc family of proteins and binds to DNA in a sequence-specific manner. We investigated the role of the helix-loop-helix (HLH), leucine zipper (LZ) and basic domains of Max in protein complex formation, DNA-binding activity and transcriptional regulation. We mutagenized the basic, HLH and LZ domains of Max and studied the ability of the normal and mutant proteins to bind to DNA as both homo- and heterodimers and their ability to heterodimerize with Myc. Helix-1 and helix-2 regions of Max were found to be critical for homodimer formation and subsequent DNA binding, while the LZ was essential for heterodimer formation. In transient transfection assays the Myc protein functioned as a transcriptional activator while Max protein repressed the trans-activation observed with Myc.
