'''RECOGNITION BY MAX OF ITS COGNATE DNA THROUGH A DIMERIC B/HLH/Z DOMAIN'''<br />


==Overview==
==RECOGNITION BY MAX OF ITS COGNATE DNA THROUGH A DIMERIC B/HLH/Z DOMAIN==
The three-dimensional structure of the basic/helix-loop-helix/leucine zipper domain of the transcription factor Max complexed with DNA has been determined by X-ray crystallography at 2.9 A resolution. Max binds as a dimer to its recognition sequence CACGTG by direct contacts between the alpha-helical basic region and the major groove. This symmetric homodimer, a new protein fold, is a parallel, left-handed, four-helix bundle, with each monomer containing two alpha-helical segments separated by a loop. The two alpha-helical segments are composed of the basic region plus helix 1 and helix 2 plus the leucine repeat, respectively. As in GCN4, the leucine repeat forms a parallel coiled coil.

Recognition by Max of its cognate DNA through a dimeric b/HLH/Z domain., Ferre-D'Amare AR, Prendergast GC, Ziff EB, Burley SK, Nature. 1993 May 6;363(6424):38-45. PMID:[http://ispc.weizmann.ac.il//pmbin/getpm?pmid=8479534 8479534]
== Function ==
[[Category: ]]
[https://www.uniprot.org/uniprot/MAX_HUMAN MAX_HUMAN] Transcription regulator. Forms a sequence-specific DNA-binding protein complex with MYC or MAD which recognizes the core sequence 5'-CAC[GA]TG-3'. The MYC-MAX complex is a transcriptional activator, whereas the MAD-MAX complex is a repressor. May repress transcription via the recruitment of a chromatin remodeling complex containing H3 'Lys-9' histone methyltransferase activity.
