Lesson plan
Sortilin
Sortilin is a protein that in humans is encoded by the SORT1 gene on chromosome 1. This protein is a type I membrane glycoprotein in the vacuolar protein sorting 10 protein (Vps10p) family of sorting receptors. While it is ubiquitously expressed in many tissues, sortilin is most abundant in the central nervous system. At the cellular level, sortilin functions in protein transport between the Golgi apparatus, endosome, lysosome, and plasma membrane, leading to its involvement in multiple biological processes such as glucose and lipid metabolism as well as neural development and cell death. Moreover, the function and role of sortilin is now emerging in several major human diseases such as hypertension, atherosclerosis, coronary artery disease, Alzheimer's disease, and cancer. The SORT1 gene also contains one of 27 loci associated with increased risk of coronary artery disease.
