Figure 1. The network of phagosomal Rab GTPases: the most common Rab proteins. This model shows the functional link between Rab proteins associated with phagosomes, interactions with different intracellular compartments and/or cytoskeletal components. As discussed in the text, studies have shown that seemingly overlapping functions are in fact more specific. MTs, microtubules; ER, endoplasmic reticulum.
