ab30532 staining LDL receptor in human lung parenchyma.
Left panel : with primary antibody at 1/400. Right panel : isotype control.
Sections were stained using an automated system (DAKO Autostainer Plus), at room temperature : sections were rehydrated and antigen retrieved with the Dako 3 in 1 AR buffers citrate pH6.1. Slides were peroxidase blocked in 3% H2O2 in methanol for 10 mins. They were then blocked with Dako Protein block for 10 minutes (containing casein 0.25% in PBS) then incubated with primary antibody for 20 min and detected with Dako envision flex amplification kit for 30 minutes. Colorimetric detection was completed with Diaminobenzidine for 5 minutes. Slides were counterstained with Haematoxylin and coverslipped under DePeX. Please note that for manual staining we recommend to optimize the primary antibody concentration and incubation time (overnight incubation), and amplification may be required.

Supplementary information

The LDL Receptor also called LDLR is a protein that plays an important role in the uptake and clearance of low-density lipoproteins (LDL) from the bloodstream. LDLR binds LDL particles facilitating their internalization through receptor-mediated endocytosis. This receptor is expressed mainly in the liver adrenal glands and other tissues involved in cholesterol metabolism. It has an approximate molecular weight of 160 kDa. Researchers often study LDLR using techniques like Western blotting to understand its presence and function.
Biological function summary

The LDL receptor interacts with LDL particles to regulate cholesterol levels in the body. It is part of a cell surface complex that recognizes and binds to apolipoprotein B-100 or apolipoprotein E present on LDL. This interaction initiates internalization of LDL leading to its degradation in lysosomes where cholesterol can be released and used by the cell. Mutations in the gene encoding LDLR can lead to inefficient cholesterol uptake influencing various metabolic processes.

Pathways

LDL receptor activities are integral to lipid metabolism and cholesterol homeostasis. Two important biological pathways that involve LDLR include the cholesterol biosynthesis pathway and the lipoprotein clearance pathway. Within these pathways LDLR collaborates closely with proteins like PCSK9 which modulates its expression and degradation and HMG-CoA reductase an important enzyme in cholesterol synthesis to balance cholesterol levels in the body.

Defects in the LDL receptor are strongly associated with familial hypercholesterolemia and atherosclerosis. These conditions arise from impaired clearance of LDL leading to elevated cholesterol levels which pose risks for cardiovascular diseases. LDLR dysfunctions are linked with the Protein PCSK9 whose gain-of-function mutations can exacerbate hypercholesterolemia by promoting degradation of LDLR while statins aim to increase LDLR expression to lower LDL cholesterol levels.

Target data

Binds low density lipoprotein /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. Forms a ternary complex with PGRMC1 and TMEM97 receptors which increases LDLR-mediated LDL internalization (PubMed : 30443021).. (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.. (Microbial infection) Acts as a receptor for Crimean-Congo hemorrhagic fever virus (CCHFV).. (Microbial infection) Acts as a receptor for many Alphavirus, including Getah virus (GETV), Ross river virus (RRV) and Semliki Forest virus.
