Sortilin (UniProt Q99523; also known as 100 kDa NT receptor, Glycoprotein 95, Gp95, Neurotensin receptor 3, NT3, NTR3) is encoded by the SORT1 (also known as LDLCQ6, NT3) gene (Gene ID 6272) in human. Sortlin belongs to the a family of sorting receptors characterized by the Vps10p domain that creates a tunnel cavity with its ten-bladed beta-propeller for the binding of soluble ligands. The family members also contain a short cytoplasmic tail that harbors recognition motifs for subcellular sorting adaptor proteins. Sortilin is reproted to bind PCSK9 in the trans-Golgi network with high-affinity in HepG2 cells. Sort1 knockout mice exhibit reduced PCSK9 plasma concentration and altered PCSK9 subcellular localization in hepatocytes. Sortilin is also found to colocalize with APP in neurites and facilitates APP processing toward the production of sAPPalpha, possibly by optimizing APP as a substrate for alpha-secretase cleavage. Sortilin is initially produced with a signal peptide (a.a. 1-33) and a propeptide (a.a. 34-77) sequence, the removal of which yields the mature receptor (a.a. 78-831) with a large luminal/extracellular (a.a. 78-555) portion, a transmembrane region (a.a. 756-778), and a short cytoplasmic tail (a.a.779-831). Similar to the other two family members (MPRs and SorLA), sortilin resides both on the membrane of intracellular vesicles and on the plasma membrane. Altered sortilin expressions due to SORT1 genetic variations affect serum levels of low density lipoprotein cholesterol (LDL-C) and contribute to the LDL-C level quantitative trait locus 6 (LDLCQ6) and susceptibility to myocardial infarction.
