Description

General description

Low-density lipoprotein receptor (UniProt P01130; also known as LDL receptor) is encoded by the LDLR (also known as FH, FHC) gene (Gene ID 3949) in human. Low-density lipoprotein (LDL) receptor recognizes the apoprotein B100 embedded in the outer phospholipid layer of cholesterol-rich LDL particles and mediates their remval by endocytosis via clathrin-coated pits. LDL receptor also recognizes the apoE protein found in chylomicron remnants and VLDL remnants (IDL). LDLR gene mutations are known causes of familial hypercholesterolaemia (FH). LDL receptor is initially produced with a signal peptide sequence (a.a. 1-21), the removal of which yields the mature single transmembrane (a.a. 789-810) protein with a C-terminal cytoplasmic tail (a.a. 811-860) and a large N-terminal extracellular region (a.a. 22-788) that contains seven class A (a.a. 25-313) and six class B (a.a. 397-658) LDLR repeats, as well as three EGF-like domains (a.a. 314-353, 354-393, 663-712). LDL-A repeats mediate LDL binding, repeats 2-7 are required for ApoB binding, while only repeat 5 is required for ApoE binding. The class B (LDL-B) repeats region adopts a beta-propeller conformation and is believed to be responsible for the pH-dependent release of LDL in the endosome. The cytoplasmic tail contains a signal sequence important for localizing the receptors to clathrin-coated pits and for triggering receptor-mediated endocytosis upon LDL binding.
