LRP-1 is a large multi-functional receptor that regulates endocytosis of multiple ligands directly or indirectly through interaction with other ligands, such as Apolipoprotein E (ApoE), α2-macroglobulin, or other receptor associated proteins many of which have been implicated in AD pathogenesis (Liu et al., 2013; Kanekiyo and Bu, 2014). The gene discussed is LRP1; the disease is Alzheimer disease.
