a transcription factor. Forms a DNA- binding protein complex with MYC or MAD. The MYC-MAX complex is a transcriptional activator, whereas the MAD-MAX complex is a repressor. CPG methylation of the recognition site greatly inhibits DNA binding, suggesting that DNA methylation may regulate the MYC/MAX complex in vivo. May repress transcription via the recruitment of a chromatin remodeling complex containing H3-K9 histone methyltransferase activity. Three alternatively spliced isoforms have been reported.
