Molecular Mass
Recombinant Human FLT3 consists of 526 amino acids and has a predicted molecular mass of 59.7 kDa. In SDS-PAGE under reducing conditions, it migRates with an apparent molecular mass of 85-95 kDa due to glycosylation.
Background
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 (PubMed:10535997, PubMed:12615904). Acts as a receptor for vesicular stomatitis virus (PubMed:23589850). In case of HIV-1 infection, may function as a receptor for extracellular Tat in neurons, mediating its internalization in uninfected cells (PubMed:11100124).
