VPS53, CT (Vacuolar Protein Sorting-associated Protein 53 Homolog, PP13624, HCCS1, hVps53L)

The sorting of acid hydrolases to lysosomes rely on mannose 6-phosphate receptors that cycle between the trans-Golgi network (TGN) and endosomes. The maintenance of this cycle requires the function of the mammalian Golgi-associated retrograde protein (GARP) complex which is composed of three subunits: VPS52, VPS53, and VPS54. Depletion of any of these three proteins, such as by RNAi, impairs the retrograde transport of multiple TGN proteins. VPS53 was identified as an HIV dependency factor (HDF) and plays a role in viral entry to the cell, suggesting that VPS53 may be an important drug target in HIV treatment. At least five isoforms of VPS53 are known to exist.\n\nApplications:\nSuitable for use in Immunofluorescence, ELISA, Western Blot and Immunocytochemistry. Other applications not tested.\n\nRecommended Dilution:\nWestern Blot: 0.5-1ug/ml\nOptimal dilutions to be determined by the researcher.\n\nPositive Control:\n293 Cell Lysate\n\nStorage and Stability:\nMay be stored at 4 degrees C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20 degrees C. Aliquots are stable for at least 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
