We conclude that MARCH8 has a very broad antiviral activity by prohibiting different viral fusion proteins from glycosylation and proteolytic cleavage in the Golgi, which inhibits their transport from the Golgi to the plasma membrane and incorporation into virions. As a control, serine incorporator 5 (SERINC5) protein In addition, FLAG-tagged furin was expressed with HA-tagged human MARCH8 and GPΔMLD in 293T cells. In addition, when the furin-VN/GP-VC pair was expressed with MARCH8, their colocalization was also detected (Fig. 2C ), confirming that these three molecules form a complex in live cells. MARCH8 proteins from different species strongly increased GP 1 and GP 1 ΔMLD expression in cells but completely blocked their secretions (Fig. 7C, lanes 1 to 8) . ./cache/cord-297082-2rhoffx2.txt ./txt/cord-297082-2rhoffx2.txt
