LDLR Recombinant Monoclonal Antibody

Uniprot Id

P01130

Target Species

Human

Target Name

LDLR

Target Full Name

Low-density lipoprotein receptor

Target Function

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.

Target Involvement

Familial hypercholesterolemia (FH)

Target Subcellular Location

Cell membrane; Single-pass type I membrane protein. Membrane, clathrin-coated pit. Golgi apparatus. Early endosome. Late endosome. Lysosome.

Target Protein Families

LDLR family

Target Synonyms

FH; FHC; LDL R; LDL receptor; LDLCQ2; Ldlr; LDLR_HUMAN; Low Density Lipoprotein Receptor; Low density lipoprotein receptor class A domain containing protein 3; Low density lipoprotein receptor familial hypercholesterolemia; Low-density lipoprotein receptor

Target Background

The low density lipoprotein receptor (LDLR) gene family consists of cell surface proteins involved in receptor-mediated endocytosis of specific ligands. The encoded protein is normally bound at the cell membrane, where it binds low density lipoprotein/cholesterol and is taken into the cell. Lysosomes release the cholesterol, which 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.
