The protein max is a member of the [[basic helix-loop-helix]] [[leucine zipper]] ([[Basic helix-loop-helix leucine zipper transcription factors|bHLHZ]]) family of [[transcription factor]]s. It is able to form homodimers and heterodimers with other family members, which include [[MXD1|Mad]], [[MXI1|Mxl1]] and [[Myc]]. Myc is an [[oncogene|oncoprotein]] implicated in [[cell growth|cell proliferation]], [[cell differentiation|differentiation]] and [[apoptosis]]. The homodimers and heterodimers compete for a common DNA target site (the [[E-box]]) and rearrangement among these dimer forms provides a complex system of transcriptional regulation. Multiple alternatively spliced transcript variants have been described for this gene but the full-length nature for some of them is unknown.<ref name="entrez"/>
The protein product of ''MAX'' contains the [[basic helix-loop-helix]] and [[leucine zipper]] motifs. It is therefore included in the [[Basic helix-loop-helix leucine zipper transcription factors|bHLHZ]] family of transcription factors. It is able to form homodimers with other MAX proteins and heterodimers with other transcription factors, including [[MXD1|Mad]], [[MXI1|Mxl1]] and [[Myc]]. The homodimers and heterodimers compete for a common DNA target site (the [[E-box]]) in a gene promoter zone. Rearrangement of dimers (e.g., Mad:Max, Max:Myc) provides a system of transcriptional regulation with greater diversity of gene targets. Max must dimerise in order to be biologically active.<ref>{{cite journal|last1=Ecevit|first1=O|last2=Khan|first2=MA|last3=Goss|first3=DJ|title=Kinetic analysis of the interaction of b/HLH/Z transcription factors Myc, Max, and Mad with cognate DNA.|journal=Biochemistry|date=30 March 2010|volume=30|issue=42|doi=10.1021/bi901913a|pmid=20170194|pmc=2852888}}</ref>


Max binds to itself and to other transcription factors through its leucine zipper to form homo- and hetero-dimers respectively. Max itself lacks a [[transactivation]] domain so that Max homodimers have a repressive function.  In contrast, Myc contains a transactivation domain but cannot homodimerize.  However Myc can heterodimerize with Max to form heterodimers that can both bind DNA and transactivate. The transcriptionally active Max/Myc dimer promotes cell proliferation as well as [[apoptosis]].<ref name="pmid8193530">{{cite journal |vauthors=Amati B, Land H | title = Myc-Max-Mad: a transcription factor network controlling cell cycle progression, differentiation and death | journal = Curr.

This is mutually exclusive with alterations at MYC and BRG1, the latter coding for an ATPase of the SWI/SNF complex. It was demonstrated that BRG1 regulates the expression of MAX through direct recruitment to the MAX promoter, and that depletion of BRG1 strongly hinders cell growth, specifically in MAX-deficient cells, heralding a synthetic lethal interaction.

MAX (also known as myc-associated factor X) is a gene that in humans encodes the MAX transcription factor.[1][2]

Function

The protein product of MAX contains the basic helix-loop-helix and leucine zipper motifs. It is therefore included in the bHLHZ family of transcription factors. It is able to form homodimers with other MAX proteins and heterodimers with other transcription factors, including Mad, Mxl1 and Myc. The homodimers and heterodimers compete for a common DNA target site (the E-box) in a gene promoter zone. Rearrangement of dimers (e.g., Mad:Max, Max:Myc) provides a system of transcriptional regulation with greater diversity of gene targets. Max must dimerise in order to be biologically active.[3]

Transcriptionally active hetero- and homodimers involving Max can promote cell proliferation as well as apoptosis.[4]

Interactions

The protein product of Max has been shown to interact with:

Clinical relevance

This gene has been shown mutated in cases of hereditary pheochromocytoma.[21] More recently the Max gene becomes mutated and becomes inactivated in small cell lung cancer (SCLC). This is mutually exclusive with alterations at Myc and BRG1, the latter coding for an ATPase of the SWI/SNF complex. It was demonstrated that the BRG1 product regulates the expression of Max through direct recruitment to the Max promoter region, and that depletion of BRG1 strongly hinders cell growth, specifically in Max-deficient cells, suggesting that the two together cause synthetic lethality. Furthermore, Max required BRG1 to activate neuroendocrine transcriptional programs and to up-regulate Myc targets, such as glycolytic-related genes.[22]
