Sortilin related receptor 1 (SORL1), a multifunctional protein, is also known as SorLA-1, LR11, LRP9 and gp250. It is a type-I transmembrane protein highly expressed in neurons. This protein belongs to the low-density lipoprotein receptor family. It contains a transmembrane domain, a large extracellular domain and a short cytoplasmic tail. SORL1 gene is located on human chromosome 11q 23/24. This mosaic receptor contains a domain that shares similarity with the vacuolar protein sorting 10 (VPS10) and with the low-density lipoprotein receptor (LDLR) family of proteins.

Sortilin related receptor 1 (SORL1) protein plays a key role in intracellular protein transport and endocytosis, cell signaling and the proliferation and migration of smooth muscle cells. It acts as a receptor for lipoproteins, glial cell-line-derived neurotrophic factor (GDNF) and platelet-derived growth factor (PDGF). Expression of this protein is developmentally regulated, with high transcript levels found during morphogenesis. SORLA is involved in development of atherosclerosis and in Alzheimer′s disease (AD). It mediates the uptake of apolipoprotein E (ApoE)-rich lipoproteins and is markedly induced in atheroma. SORL1 is known to play a regulating role in trafficking and processing of the amyloid precursor protein (APP) in neuronal cells. In the Golgi, SorLA/LR11 binding of APP leads to sequestration of APP and thereby it blocks the processing to the beta-amyloid peptide.

Storage and Stability
Store at –20 °C. For continuous use, the product may be stored at 2–8 °C for up to one month. For extended storage, freeze in working aliquots at –20 °C. Repeated freezing and thawing, or storage in “frost-free” freezers, is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use. Working dilutions should be discarded if not used within 12 hours.
