Cellular localization of INVs. Schematic diagram showing the cellular pathways on which the Rab GTPases operate. Rabs are represented by their number. Red and gray numbers indicate positive and negative Rab hits, respectively. Red and black arrows indicate pathways that involve a Rab that is a positive hit or where only negative hits were found, respectively. INVs are shown as purple vesicles peppered throughout most, but not all, of the network. The inset summarizes the three types of protein found on INVs that were tested in the present study.
