Figure 6From: The YXXΦ motif within the severe acute respiratory syndrome coronavirus (SARS-CoV) 3a protein is crucial for its intracellular transportA model of intracellular trafficking of the 3a protein. The wild type 3a protein or the ∆EXD mutant are sorted from Golgi to plasma membrane whereas the ∆YXXΦ mutant protein is retained in the Golgi and is targeted to lysosomal compartment for degradation via lipid droplets.Back to article page
