  Function in Host
The small GTPases Rab are key regulators of intracellularmembrane trafficking, from the formation of transport vesicles to theirfusion with membranes. Rabs cycle between active GTP-bound and inactiveGDP-bound states. In their active state, drive transport of vesicularcarriers from donor organelles to acceptor organelles to regulate themembrane traffic that maintains organelle identity and morphology. Regulates the compacted morphology of the Golgi. Seems to have a role in retrograde membrane trafficat the level of the Golgi complex. May function in retrograde transportin neuronal cells. [1]

Function of This Protein During Virus Infection
Virus NameSARS-COV-2 Protein Function Anti-viral [2]
Infected TissueLung Infection Time7-9 Days
Infected CellCalu-3 Cells (Human epithelial cell line) Cellosaurus IDCVCL_0609 
Method DescriptionTo detect the role of host protein RAB6B in viral infection, RAB6B protein Knockdown Calu-3 Cells were infected with SARS-COV-2 for 7 - 9 Days , and the effects on infection was detected through CRISPR-based genome-wide gene-knockout screen.
ResultsIt is reported that knockout of RAB6B increases SARS-CoV-2 RNA levels compared with control group.
