    basic FUNCTION
  • MYC-MAX complex is a transcriptional activator, whereas the MAD-MAX complex is a repressor
  • is the obligatory DNA-binding and dimerization partner for all the bHLHZip regulators of the Myc/Max/Mad network, including the Myc family of oncoproteins and the Mad family of Myc antagonists, which recognize E-box DNA elements in the regulatory regions of target genes
  • is a constitutively expressed and phosphorylated protein
  • key role for the MYC-MAX-MXD1 network in the development and progression of neural crest tumors
  • MAX prevents ectopic and precocious meiosis in embryonic stem cells (ESCs) and germ cells, respectively
  • "clock" function of MAX is required for maintaining a proper circadian rhythm and MAX and ARNTL contribute to two temporally alternating transcriptional complexes on clock-regulated promoters
  • MAX regulates clock gene expression and contributes to keeping the balance between positive and negative elements of the molecular clock machinery
  • CELLULAR PROCESS nucleotide, transcription, regulation
    PHYSIOLOGICAL PROCESS
    PATHWAY
    metabolism
    signaling signal transduction
    a component
  • heterodimerizing with MYC, with high affinity for the DNA-binding site of MYC (transcriptional activator)
  • heterodimerizing with MAD (transcriptional repressor)
  • forms a specific DNA-binding complex with MYC
  • part of the MYC-MAX-MXD1 network
  • INTERACTION
    DNA binding
    RNA
    small molecule
    protein
  • MAD and MNT binding
  • requires dimerization with another bHLH protein to efficient DNA binding
  • MYC and MNT use MAX as a cofactor for DNA binding
  • MYC, ZBTB17 and MAX are associated with the CEBPD promoter in proliferating cells, when CEBPD expression is repressed
  • deacetylation of MYC by SIRT1 promotes its association with MAX, a partner essential for its activation, thereby facilitating MYC transactivation activity on TERT promoter
  • MAX deficiency impairs human endometrial decidualization through down-regulating OSR2 in women with recurrent spontaneous abortion
