Identification
HMDB Protein ID CDBP01764
Secondary Accession Numbers Not Available
Name Low-density lipoprotein receptor
Description Not Available
Synonyms
  1. LDL receptor
Gene Name LDLR
Protein Type Enzyme
Biological Properties
General Function Involved in calcium ion binding
Specific 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
