Allgemeine Beschreibung
The protein encoded by this gene is a member of the basic helix-loop-helix leucine zipper (bHLHZ) family of transcription factors. It is able to form homodimers and heterodimers with other family members, which include Mad, Mxi1 and Myc. Myc is an oncoprotein implicated in cell proliferation, 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. (provided by RefSeq)
Biochem/physiol Actions
Myc-associated factor X (MAX) interacts with N-, L-, and c-Myc proteins both in vitro and in vivo. MAX plays a vital role in the regulation of the MYC/MAX/ MAX dimerization protein (MXD) network of basic helix-loop-helix leucine zipper (bHLHZip) transcription factors implicated in cell proliferation, differentiation, and apoptosis. Mutation of the gene leads to pheochromocytomas and paragangliomas (PPGLs). Heterodimer complex of c-Myc and Max proteins stimulates the transcription at target promoters by binding hexameric DNA consensus sequences “CANNTG” (E-boxes). Apart from this, Max hinders MYC-dependent cell transformation by transcriptional repression of the same E-boxes by associating with various repressors such as MXD, MAX network transcriptional repressor (MNT), and MAX gene-associated protein (MGA). Gene transcription activated by MYC–MAX heterodimers can be repressed by Max homodimers by decreasing the level of free MAX monomers and by binding to E-box DNA sequences.
