target relevance
The low density lipoprotein receptor (LDLR) is the founding member of the LDL R family of widely expressed cell surface scavenger receptors. It is a cell-surface receptor that recognizes the apoprotein B100 which is embedded in the phospholipid outer layer of LDL particles.

LDLR family
FUNCTION: 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). {ECO:0000269|PubMed:3005267, ECO:0000269|PubMed:30443021, ECO:0000269|PubMed:6091915}.; FUNCTION: (Microbial infection) Acts as a receptor for hepatitis C virus in hepatocytes, but not through a direct interaction with viral proteins. {ECO:0000269|PubMed:10535997, ECO:0000269|PubMed:12615904}.; FUNCTION: (Microbial infection) Acts as a receptor for Vesicular stomatitis virus. {ECO:0000269|PubMed:23589850}.; FUNCTION: (Microbial infection) In case of HIV-1 infection, may function as a receptor for extracellular Tat in neurons, mediating its internalization in uninfected cells. {ECO:0000269|PubMed:11100124}.; FUNCTION: (Microbial infection) Acts as a receptor for Crimean-Congo hemorrhagic fever virus (CCHFV). {ECO:0000269|PubMed:38182887}.; FUNCTION: (Microbial infection) Acts as a receptor for many Alphavirus, including Getah virus (GETV), Ross river virus (RRV) and Semliki Forest virus. {ECO:0000269|PubMed:38182887}.
