DESCRIPTION

Also known as LRP1_HUMAN, LRP1, A2MR, APR. Endocytic receptor involved in endocytosis and in phagocytosis of apoptotic cells (PubMed:11907044, PubMed:12713657). Required for early embryonic development (By similarity). Involved in cellular lipid homeostasis. Involved in the plasma clearance of chylomicron remnants and activated LRPAP1 (alpha 2-macroglobulin), as well as the local metabolism of complexes between plasminogen activators and their endogenous inhibitors. Acts as an LRPAP1 alpha-2-macroglobulin receptor (PubMed:26142438, PubMed:1702392). Acts as TAU/MAPT receptor and controls the endocytosis of TAU/MAPT as well as its subsequent spread (PubMed:32296178). May modulate cellular events, such as APP metabolism, kinase-dependent intracellular signaling, neuronal calcium signaling as well as neurotransmission (PubMed:12888553)., (Microbial infection) Functions as a receptor for Pseudomonas aeruginosa exotoxin A. Heterodimer of an 85-kDa membrane-bound carboxyl subunit and a non-covalently attached 515-kDa N-terminal subunit. Intracellular domain interacts with MAFB (By similarity). Found in a complex with PID1/PCLI1, LRP1 and CUBNI (PubMed:17124247). Interacts with SNX17, PID1/PCLI1, PDGF and CUBN. The intracellular domain interacts with SHC1, GULP1 and DAB1. Can weakly interact (via NPXY motif) with DAB2 (via PID domain); the interaction is enhanced by tyrosine phosphorylation of the NPXY motif. Interacts with MDK; promotes neuronal survival (PubMed:10772929). Interacts with LRPAP1; this interaction is followed by rapid internalization (PubMed:15053742, PubMed:32296178, PubMed:16938309). Interacts with uPA/PLAU and PAI1/SERPINE1, either individually or in complex with each other, leading to rapid endocytosis; this interaction is abolished in the presence of LRPAP1/RAP (PubMed:15053742). Also interacts with tPA/PLAT alone or in complex with SERPINE1 (PubMed:15053742). Interacts with the urokinase receptor PLAUR; this interaction leads to PLAUR internalization and is impaired in the presence of SORL1 (PubMed:14764453). Interacts with PDGFB (PubMed:15053742). Interacts with TAU/MAPT, leading to endocytosis; this interaction is reduced in the presence of LRPAP1/RAP (PubMed:32296178).
