'''LDL (Low Density Lipoprotein) receptor''' (LDLR) mediates the endocytosis of cholesterol-rich LDL. LDLR recognizes the apoprotein B100 which is embedded in the outer layer of the LDL particle. LDLR sits on the cell surface and binds LDL particles which circulate in the blood stream. LDLR transports the LDL particle into the cell where the cholesterol is used. Upon release of the LDL particle, the LDLR is recycled back into the cell membrane surface<ref>PMID:19299327</ref>. | '''LDL (Low Density Lipoprotein) receptor''' (LDLR) mediates the endocytosis of cholesterol-rich LDL.
