Abstract: The invention provides a method of screening a substance for the ability to effect the formation of a retinoid X receptor homodimer comprising combining the substance and a solution containing retinoid X receptors and determining the presence of homodimer formation. Also provided is a method of screening a substance for an effect on a retinoid X receptor homodimer's ability to bind DNA comprising combining the substance with the homodimer and determining the effect of the compound on the homodimer's ability to bind DNA. A method of inhibiting an activity of a retinoid X receptor heterodimer comprising increasing the formation of a retinoid X receptor homodimer, thereby preventing the retinoid X receptor from forming a heterodimer and preventing the resulting heterodimer activity is also provided. A method of inhibiting an activity of a retinoid X receptor homodimer is also provided.
