Application Abreviews Notes
WB 1/1000. Detects a band of approximately 68, 100 kDa.
This antibody has been tested on recombinant protein only. We have not tested it on endogenous protein.


  • 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. In case of HIV-1 infection, functions as a receptor for extracellular Tat in neurons, mediating its internalization in uninfected cells.
  • Involvement in disease
    Defects in LDLR are the cause of familial hypercholesterolemia (FH) [MIM:143890]; a common autosomal semi-dominant disease that affects about 1 in 500 individuals. The receptor defect impairs the catabolism of LDL, and the resultant elevation in plasma LDL-cholesterol promotes deposition of cholesterol in the skin (xanthelasma), tendons (xanthomas), and coronary arteries (atherosclerosis).
  • Sequence similarities
    Belongs to the LDLR family.
    Contains 3 EGF-like domains.
    Contains 7 LDL-receptor class A domains.
    Contains 6 LDL-receptor class B repeats.
  • Post-translational
    N- and O-glycosylated.
    Ubiquitinated by MYLIP leading to degradation.
  • Cellular localization
    Cell membrane. Endomembrane system. Membrane > clathrin-coated pit. Found distributed from the plasma membrane to intracellular compartments.

Submitted Feb 22 2007

Thank you for your enquiry. For ab14056, this was tested against a fusion protein corresponding to amino acids 29 to 205 of the human LDL receptor. Thus, the bands seen will be much smaller than for the full-length protein. Native LDLR will run as...
