Inhibitor Of DNA-binding Protein
Inhibitor of DNA-binding/differentiation proteins, also known as Id proteins comprise a family of proteins that heterodimerize with basic helix-loop-helix (bHLH) transcription factors to inhibit DNA binding of bHLH proteins. Id proteins also contain the HLH-dimerization domain but lack the basic DNA-binding domain and thus negatively regulate bHLH transcription factors when they heterodimermize with bHLH proteins.

Famous quotes containing the word protein:
“Firm-style bean curd insoles cushion feet, absorb perspiration and provide more protein than meat or fish innersoles of twice the weight. Tofu compresses with use, becoming more pungent and flavorful. May be removed when not in use to dry or marinate. Innersoles are ready to eat after 1,200 miles of wear. Each pair provides adult protein requirement for 2 meals. Insoles are sized large to allow for snacks. Recipe booklet included.”
