MAD protein is a protein that in humans is encoded by the MXD1 gene.^[5][6]

MAD-MAX dimerization protein belongs to a subfamily of MAX-interacting proteins. This protein competes with MYC for binding to MAX to form a sequence-specific DNA-binding complex, acts as a transcriptional repressor (while MYC appears to function as an activator) and is a candidate tumor suppressor.^[6]

Interactions

MXD1 has been shown to interact with Histone deacetylase 2,^[7][8] SMC3,^[9] MLX,^[10][11] SIN3A^[12][13][14] and MAX.^{[9][15][16][17]}
