Rab interacting lysosomal protein (RILP) contains a domain which contains two coiled-coil regions and is found mainly in the cytosol. RILP is recruited onto late endosomal and lysosomal membranes by Rab7 and acts as a downstream effector of Rab7 []. This recruitment process is important for phagosome maturation and fusion with late endosomes and lysosomes.
