NCIt synonyms : MXI1; MAX Interacting Protein-1; MAX Dimerization Protein 2; bHLHc11; Class C Basic Helix-Loop-Helix Protein 11; Max Interactor 1; MAX Interacting Protein 1; MAD2;
NCIt definition : Max-interacting protein 1 (228 aa, 26 kDa) is encoded by the human MXI1 gene. This
protein plays a role in transcription factor binding and transcriptional repression.;
NCIt note : MAX Interacting Protein 1, encoded by the MXI1 gene, is a transcriptional repressor
thought to negatively regulate MYC function, and is therefore a potential tumor suppressor.
This protein inhibits the transcriptional activity of MYC by competing for MAX, another
basic helix-loop-helix protein that binds to MYC and is required for its function.;
