The LDL-receptor (red) is a membrane protein found in almost every human cell. It binds to the apoprotein B100 from LDL-particles and mediates their internalization (endocytosis) in the cell. This occurs in almost all cells but mainly in the liver where it removes about 70 % of LDL from the circulation.
