CC -!- FUNCTION: Small GTPase which cycles between active GTP-bound and
CC inactive GDP-bound states. In its active state, binds to a variety of
CC effector proteins playing a key role in the regulation of endo-
CC lysosomal trafficking. Governs early-to-late endosomal maturation,
CC microtubule minus-end as well as plus-end directed endosomal migration
CC and positioning, and endosome-lysosome transport through different
CC protein-protein interaction cascades (By similarity). Plays a central
CC role, not only in endosomal traffic, but also in many other cellular
CC and physiological events, such as growth-factor-mediated cell
CC signaling, nutrient-transporter-mediated nutrient uptake, neurotrophin
CC transport in the axons of neurons and lipid metabolism (By similarity).
CC Also involved in regulation of some specialized endosomal membrane
CC trafficking, such as maturation of melanosomes, pathogen-induced
CC phagosomes (or vacuoles) and autophagosomes (By similarity). Plays a
CC role in the maturation and acidification of phagosomes that engulf
CC pathogens, such as S.aureus and Mycobacteria (By similarity). Plays a
CC role in the fusion of phagosomes with lysosomes (By similarity). Plays
CC important roles in microbial pathogen infection and survival, as well
CC as in participating in the life cycle of viruses (By similarity).
CC Microbial pathogens possess survival strategies governed by RAB7A,
CC sometimes by employing RAB7A function (e.g. Salmonella) and sometimes
CC by excluding RAB7A function (e.g. Mycobacterium) (By similarity). In
CC concert with RAC1, plays a role in regulating the formation of RBs
CC (ruffled borders) in osteoclasts (By similarity). Controls the
CC endosomal trafficking and neurite outgrowth signaling of NTRK1/TRKA (By
CC similarity). Regulates the endocytic trafficking of the EGF-EGFR
CC complex by regulating its lysosomal degradation (By similarity).
CC Involved in the ADRB2-stimulated lipolysis through lipophagy, a
CC cytosolic lipase-independent autophagic pathway. Required for the
CC exosomal release of SDCBP, CD63 and syndecan (By similarity). Required
CC for vesicular trafficking and cell surface expression of ACE2 (By
CC similarity). May play a role in PRPH neuronal intermediate filament
CC assembly (By similarity). {ECO:0000250|UniProtKB:P51149,
