Résumé UniProt
Endocytic receptor involved in endocytosis and in phagocytosis of apoptotic cells. Required for early embryonic development. 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. May modulate cellular events, such as APP metabolism, kinase-dependent intracellular signaling, neuronal calcium signaling as well as neurotransmission (PubMed:11907044, PubMed:12888553, PubMed:12713657). Acts as an alpha-2-macroglobulin receptor (PubMed:26142438).
Résumé Entrez
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.
Spécificité tissulaire
Most abundant in liver, brain and lung.
Implication dans la maladie
Keratosis pilaris atrophicans: A group of rare genodermatoses characterized by keratotic follicular papules, variable degrees of inflammation, and secondary atrophic scarring. Most cases are associated with an atopic diathesis and keratosis pilaris on the extensor extremities. KPA is comprised of three distinct clinical subtypes: keratosis pilaris atrophicans faciei, atrophoderma vermiculatum, and keratosis follicularis spinulosa decalvans. Affected individuals may present with features overlapping the 3 subtypes.
Similitudes de séquence
Belongs to the LDLR family.
Modification post-traductionnelle
Cleaved into a 85 kDa membrane-spanning subunit (LRP-85) and a 515 kDa large extracellular domain (LRP-515) that remains non-covalently associated. Gamma-secretase-dependent cleavage of LRP-85 releases the intracellular domain from the membrane.
