Prolow-Density Lipoprotein Receptor-Related Protein 1 (LRP1) ELISA Kit for Human

This gene encodes a member of the low-density lipoprotein receptor family of proteins. The encoded preproprotein is proteolytically processed by furin to generate 515 kDa and 85 kDa subunits that form the mature receptor (PMID: 8546712). This receptor is involved in several cellular processes, including intracellular signaling, lipid homeostasis, and clearance of apoptotic cells. In addition, the encoded protein is necessary for the alpha 2-macroglobulin-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's disease patients. [provided by RefSeq, Oct 2015]

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. Involved in the plasma clearance of chylomicron remnants and activated alpha 2-macroglobulin, as well as the local metabolism of complexes between plasminogen activators and their endogenous inhibitors. Plays a fundamental role in cellular signaling pathways in the brain. Mediates neural NMDA gating via a complex of LRP1, PSD-95 and NMDAR. A type I membrane protein. After cleavage, the intracellular domain (LRPICD) is detected both in the cytoplasm and in the nucleus. Most abundant in liver, brain and lung.
