VSV G protein has been a very useful tracker protein for both living cell and in vitro assays because

#Unit 3. Fundamental Processes

a temperature sensitive mutation in the protein permits reversible accumulation of the protein in the ER.
the protein is much smaller than most cellular proteins and therefore can be readily identified by SDS-PAGE.
fusion proteins with VSV G retain the temperature-sensitive properties of VSV G.
the protein is N-glycosylated and hence its trafficking can be inferred from its glycosylation state.
