 RESEARCH OVERVIEW
 
The Brown/Goldstein laboratory is unique in medical research because it has been supervised jointly by two scientists for 33 years. The laboratory is devoted to solving a fundamental problem: how do animals regulate the synthesis of cholesterol and other lipids so as to maintain constant membrane composition? Several years ago we discovered sterol regulatory element-binding proteins (SREBPs), membrane-bound transcription factors that activate genes encoding more than 30 enzymes required for lipid synthesis, uptake and storage. To reach the nucleus the SREBPs must travel to the Golgi complex where proteases release the active transcription domains. We call this the SREBP pathway. Excess cholesterol blocks SREBP movement, thus inhibiting lipid synthesis and establishing a feedback loop. Defects in SREBP regulation contribute to common diseases, ranging from heart attacks to obesity and diabetes.
