ResumoProtein–protein interaction cascades are crucial for cellular signaling pathways and cell morphogenesis. Membrane traffic along the secretory and endocytic pathways is similarly governed by regulated protein–protein interactions of diverse machineries, which are inter-regulated, assembled and disassembled sequentially to drive membrane budding, vesicle transport, membrane fission and fusion. Rab7, the key regulator in endo-lysosomal trafficking investigated extensively in the past decades, is emerging to govern early-to-late endosomal maturation, microtubule minus-end as well as plus-end directed endosomal migration and positioning, and endosome–lysosome transport through different protein–protein interaction cascades. We summarize here the key protein interaction cascades of Rab7 by focusing on endo-lysosomal trafficking regulated by its interaction with HOPs, RILP, ORP1L, FYCO1 and Mon1/Sand1-CCZ1 complex.
