transcription factor-like protein 4, transcription factor-like 4, MAX-like bHLHZIP protein, BigMax protein, bHLHd13, TCFL4, MXD7, MAD7, MAX-like protein X, MLX

The product of this gene belongs to the family of basic helix-loop-helix leucine zipper (bHLH-Zip) transcription factors. These factors form heterodimers with Mad proteins and play a role in proliferation, determination and differentiation. This gene product may act to diversify Mad family function by its restricted association with a subset of the Mad family of transcriptional repressors, namely, Mad1 and Mad4. Alternatively spliced transcript variants encoding different isoforms have been identified for this gene.
