Sterols are essential structural components of cell membranes and have functions in many different physiological processes. For example, brassinosteroids are a class of sterol phytohormones that are important in regulating plant growth and development. This study describes the identification of a protein factor that regulates sterol homeostasis in Arabidopsis.
