Post Translational Modifications
Cleaved into a 85kDa membrane-spanning subunit (LRP-85) and a 515kDa large extracellular domain (LRP-515) that remains non-covalently associated. Gamma-secretase-dependent cleavage of LRP-85 releases the intracellular domain from the membrane.The N-terminus is blocked.Phosphorylated on serine and threonine residues.Phosphorylated on tyrosine residues upon stimulation with PDGF. Tyrosine phosphorylation promotes interaction with SHC1.
Subunit Structure
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. Interacts with SNX17, PID1/PCLI1, PDGF and CUBN. The intracellular domain interacts with SHC1, GULP1 and DAB1. Interacts with LRPAP1. Can weakly interact (via NPXY motif) with DAB2 (via PID domain); the interaction is enhanced by tyrosine phosphorylation of the NPXY motif. Interacts with bacterial exotoxins. Interacts with MDK; promotes neuronal survival. 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. Also interacts with tPA/PLAT alone or in complex with SERPINE1. Interacts with the urokinase receptor PLAUR; this interaction leads to PLAUR internalization and is impaired in the presence of SORL1. Interacts with LRPAP1; this interaction is followed by rapid internalization. Interacts with PDGFB.
Similarity
Belongs to the LDLR family.
Subcellular Location
Cell membrane>Single-pass type I membrane protein. Membrane>Coated pit. Cell membrane>Peripheral membrane protein>Extracellular side. Membrane>Coated pit. Cytoplasm. Nucleus.
Note: After cleavage, the intracellular domain (LRPICD) is detected both in the cytoplasm and in the nucleus.Postsynaptic Golgi apparatus. Cytoplasm>Cytoskeleton>Microtubule organizing center.
Note: Localizes to the postsynaptic Golgi apparatus region, also named Golgi outpost, which shapes dendrite morphology by functioning as sites of acentrosomal microtubule nucleation.
Preparation and Storage
Store at -20 degree C. Stable for 12 months from date of receipt.

NCBI Description

The protein encoded by this gene is an endocytic receptor involved in several cellular processes, including intracellular signaling, lipid homeostasis, and clearance of apoptotic cells. In addition, the encoded protein is necessary for the A2M-mediated clearance of secreted amyloid precursor protein and beta-amyloid, the main component of amyloid plaques found in Alzheimer patients. Expression of this gene decreases with age and has been found to be lower than controls in brain tissue from Alzheimer patients. [provided by RefSeq, Jan 2010]

Uniprot Description

LRP1: a receptor involved in endocytosis, phagocytosis of apoptotic cells, and neural signaling. Modulates cellular events including APP metabolism, kinase-dependent intracellular signaling, neuronal calcium signaling and neurotransmission.

It is sometimes possible for the material contained within the vial of "LRP1/CD91, Polyclonal Antibody" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.
