Trans-Golgi network integral membrane protein 2 (TGOLN2) is a heterodimeric type I integral membrane protein. It has a highly conserved N terminus which consists of a signal peptide. The C terminus comprises part of the lumenal domain, a membrane spanning region and cytoplasmic tail.
Synonyms: Anti-TGN38 homolog; Anti-TGN46; Anti-TGN48; Anti-Trans-Golgi network integral membrane protein 2 precursor; Anti-Trans-Golgi network protein TGN51
Storage: -20C
Application: Anti-TGOLN2 antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org). Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige.
Biochem Physiol Actions: Trans-Golgi network integral membrane protein 2 (TGOLN2) cycles between the trans-golgi network (TGN) and the cell surface via an early endosomal compartment. This movement is mediated by a tyrosine-based tetra peptide signal (SDYQRL) in the cytoplasmic domain. It plays an important role in the formation of exocytic vesicles at the TGN by functioning as a receptor for complexes of a cytoplasmic protein known as p62 and a GTP-binding protein. The cytoplasmic domain of TGOLN2 binds to the complex and is essential for budding to occur. Coupling of the segregation of secretory proteins to the budding of exocytic vesicles is mediated by it. The cytosolic domain of TGOLN2 interacts with a complex of four adaptins, called AP2 clathrin adaptor complex and also with the coiled coil region of a protein called neurabin.
