UniProt Protein Function: | Mad4: Transcriptional repressor. Binds with MAX to form a sequence-specific DNA-binding protein complex which recognizes the core sequence 5'-CAC[GA]TG-3'. Antagonizes MYC transcriptional activity by competing for MAX and suppresses MYC dependent cell transformation. |
UniProt Protein Details: | Chromosomal Location of Human Ortholog: 4p16.3 Cellular Component: nucleus Molecular Function:DNA binding; protein binding; protein dimerization activity; transcription corepressor activity Biological Process: negative regulation of cell proliferation; negative regulation of transcription from RNA polymerase II promoter; transcription, DNA-dependent |
NCBI Summary: | This gene is a member of the MAD gene family . The MAD genes encode basic helix-loop-helix-leucine zipper proteins that heterodimerize with MAX protein, forming a transcriptional repression complex. The MAD proteins compete for MAX binding with MYC, which heterodimerizes with MAX forming a transcriptional activation complex. Studies in rodents suggest that the MAD genes are tumor suppressors and contribute to the regulation of cell growth in differentiating tissues. [provided by RefSeq, Jul 2008] |
