Primary gene name(s)SORT1

Protein nameSortilin
Protein functionFunctions 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. {ECO:0000269|PubMed:10085125, ECO:0000269|PubMed:11331584, ECO:0000269|PubMed:11390366, ECO:0000269|PubMed:12209882, ECO:0000269|PubMed:12598608, ECO:0000269|PubMed:14657016, ECO:0000269|PubMed:14985763, ECO:0000269|PubMed:15313463, ECO:0000269|PubMed:15930396, ECO:0000269|PubMed:15987945}.

Single-pass type I membrane protein {ECO:0000305}. Note=Localized to membranes of the endoplasmic reticulum, endosomes, Golgi stack, lysosomes and nucleus. A small fraction of the protein is also localized to the plasma membrane. May also be found in SLC2A4/GLUT4 storage vesicles, GSVs in adipocytes. Localization to the plasma membrane in adipocytes may be enhanced by insulin.
