Low-density lipoprotein receptor (LDL receptor) is a cell surface protein which is responsible for the cholesterol supply of the cell. The receptor recognizes the protein B100 which is part of the LDL particles. Binding of the B100 protein to the LDL receptor leads to endocytosis via clathrin coated pits. The vesicle fuses with an endosome, the resulting shift in the pH value leads to the detachment of the LDL. The receptor can be transported back to the plasma membrane (receptor recycling). Through this process the cell takes up the cholesterol which is associated with LDL. LDL accumulation in the blood is responsible for Atherosclerosis and many cardiovascular diseases. The LDL gene is regulated by the intracellular level of cholesterol. A low level of cholesterol leads to the activation whereas a high level results in a decrease of transcription.

LDL receptor promoter (sterol regulated)

This part is an LDL receptor responsive element which when placed upstream of other genes could induce their transcription in response to lipid addition to the medium.
