Max-like protein X is a protein that in humans is encoded by the MLX gene.^[1][2]

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.^[2]

Interactions

MLX (gene) has been shown to interact with MNT,^[3][4] MXD1^[3][4] and MLXIPL.^[3]
