The low density lipoprotein receptor (LDLR) gene family consists of cell surface proteins involved in receptor-mediated endocytosis of specific ligands. Low density lipoprotein (LDL) is normally bound at the cell membrane and taken into the cell ending up in lysosomes where the protein is degraded and the cholesterol is made available for repression of microsomal enzyme 3-hydro...

Summaries for LDLR Gene

Entrez Gene Summary for LDLR Gene

  • The low density lipoprotein receptor (LDLR) gene family consists of cell surface proteins involved in receptor-mediated endocytosis of specific ligands. Low density lipoprotein (LDL) is normally bound at the cell membrane and taken into the cell ending up in lysosomes where the protein is degraded and the cholesterol is made available for repression of microsomal enzyme 3-hydroxy-3-methylglutaryl coenzyme A (HMG CoA) reductase, the rate-limiting step in cholesterol synthesis. At the same time, a reciprocal stimulation of cholesterol ester synthesis takes place. Mutations in this gene cause the autosomal dominant disorder, familial hypercholesterolemia. Alternate splicing results in multiple transcript variants.[provided by RefSeq, Sep 2010]

GeneCards Summary for LDLR Gene

LDLR (Low Density Lipoprotein Receptor) is a Protein Coding gene. Diseases associated with LDLR include Hypercholesterolemia, Familial, 1 and Familial Hypercholesterolemia. Among its related pathways are Vesicle-mediated transport and Wnt Signaling Pathway and Pluripotency. Gene Ontology (GO) annotations related to this gene include calcium ion binding and low-density lipoprotein particle binding. An important paralog of this gene is LRP8.

UniProtKB/Swiss-Prot Summary for LDLR Gene

  • Binds LDL, the major cholesterol-carrying lipoprotein of plasma, and transports it into cells by endocytosis. In order to be internalized, the receptor-ligand complexes must first cluster into clathrin-coated pits.
  • (Microbial infection) Acts as a receptor for hepatitis C virus in hepatocytes, but not through a direct interaction with viral proteins.
  • (Microbial infection) Acts as a receptor for Vesicular stomatitis virus.
  • (Microbial infection) In case of HIV-1 infection, may function as a receptor for extracellular Tat in neurons, mediating its internalization in uninfected cells.
