In normal cells, FOS and MYC mRNAs and the proteins they encode are intrinsically unstable and degrade rapidly after the genes are transcribed, Conversion of the MYC proto-oncogene into an oncogene can occur by different mechanisms, Other members of this protein set include MAD, MAX, and MNT, choose incorrect statement regarding this,

#Unit 4. Cell Communication and Cell Signaling
  1. MYC-MAX dimers regulate genes that control proliferation, such as cyclins. 
  2. MAD and MNT work with the SIN3 co-repressor protein to bring in histone deacetylases that help to block transcription.
  3. MAD proteins inhibit MYC proteins, which has led to an interest in using MAD proteins, or drugs that stimulate MAD proteins, to rein in excessive MYC activity that contributes to tumor formation.
  4. MYC protein complexes affect transcription by recruiting chromatin-modifying complexes containing histone deacetyl transferases.
