Key tethering protein found to transport cellular cholesterol

Despite its less-than-stellar reputation in the news, cholesterol is an essential molecule for living things. It serves as the building block for hormones and gives shape to the membranes that enclose cells and their internal parts (Fig.1). Consequently, many diseases arise from defects in the proper transport of cholesterol. Now, researchers at Osaka University have shed new light on one of the key pathways used to transport cholesterol inside of cells.
