MXI1 - MAX interactor 1, dimerization protein Gene
Also Known as MXI; MAD2; MXD2; bHLHc11
Species: Homo sapiens
About MXI1
This gene has 38 transcripts (splice variants), 258 orthologues, 4 paralogues and is associated with 1 phenotype. Ubiquitous expression in ovary (RPKM 23.6), brain (RPKM 22.2) and 25 other tissues.
Summary
Expression of the c-Myc gene, which produces an oncogenic transcription factor, is tightly regulated in normal cells but is frequently deregulated in human cancers. The protein encoded by this 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. Defects in this gene are frequently found in patients with prostate tumors. Three alternatively spliced transcripts encoding different isoforms have been described. Additional alternatively spliced transcripts may exist but the products of these transcripts have not been verified experimentally. [provided by RefSeq, Jul 2008]
