ChREBP (carbohydrate response element-binding protein) is a glucose responsive basic helix-loop-helix/leucine zipper (bHLH/LZ) transcription factor that binds MLX and then carbohydrate response element /ChoRE for the induction of genes involved in glycolysis, de novo lipogenesis (DNL), and fatty acid desaturation. ChREBP’s target genes includes glucokinase (GCK), fatty acid synthase (FAS), acetyl-CoA carboxylase (ACC), pyruvate kinase/liver type pyruvate kinase (PK1/ PKLR), delta-9-desaturase (SCD/SCD1) etc.
