Definition of the transcriptional activation domains of three human HOX proteins depends on the DNA-binding context.

Abstract excerpt

Hox proteins control developmental patterns and cell differentiation in vertebrates by acting as positive or negative regulators of still unidentified downstream target genes. The homeodomain and other small accessory sequences encode the DNA-protein and protein-protein interaction functions which ultimately dictate target recognition and functional specificity in vivo. The effector domains responsible for either...
