|FUNCTION: Functions as a sorting receptor in the Golgi compartment and as a clearance receptor on the cell surface. Required for protein transport from the Golgi apparatus to the lysosomes by a pathway that is independent of the mannose-6-phosphate receptor (M6PR). Also required for protein transport from the Golgi apparatus to the endosomes. Promotes neuronal apoptosis by mediating endocytosis of the proapoptotic precursor forms of BDNF (proBDNF) and NGFB (proNGFB). Also acts as a receptor for neurotensin. May promote mineralization of the extracellular matrix during osteogenic differentiation by scavenging extracellular LPL. Probably required in adipocytes for the formation of specialized storage vesicles containing the glucose transporter SLC2A4/GLUT4 (GLUT4 storage vesicles, or GSVs). These vesicles provide a stable pool of SLC2A4 and confer increased responsiveness to insulin. May also mediate transport from the endoplasmic reticulum to the Golgi. SUBUNIT: Interacts with LPL and SLC2A4 (By similarity). Interacts with the cytosolic adapter proteins GGA1 and GGA2. Interacts with numerous ligands including the receptor-associated protein LRPAP1/RAP, GM2A, NTS and PSAP. Forms a complex with NGFR which binds specifically to the precursor forms of NGFB (proNGFB) and BDNF (proBDNF). Interacts with the Trk receptors NTRK1, NTRK2 and NTRK3; may regulate their anterograde axonal transport and signaling. TISSUE SPECIFICITY: Expressed in brain and prostate (at protein level). Expressed at high levels in brain, spinal cord, heart, skeletal muscle, thyroid, placenta and testis. Expressed at lower levels in lymphoid organs, kidney, colon and liver. INDUCTION: During osteoblast differentiation. DOMAIN: The N-terminal propeptide may facilitate precursor transport within the Golgi stack. Intrachain binding of the N- terminal propeptide and the extracellular domain may also inhibit premature ligand binding. DOMAIN: The extracellular domain may be shed following protease cleavage in some cell types. DISEASE: Note=A common polymorphism located in a non-coding region between CELSR2 and PSRC1 alters a CEBP transcription factor binding site and is responsible for changes in hepatic expression of SORT1. Altered SORT1 expression in liver affects low density lipoprotein cholesterol levels in plasma and is associated with susceptibility to myocardial infarction.|
