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 to regulate cellular responses such as of
CC intracellular membrane trafficking, from the formation of transport
CC vesicles to their fusion with membranes. Active GTP-bound form is able
CC to recruit to membranes different sets of downstream effectors directly
CC responsible for vesicle formation, movement, tethering and fusion.
CC RAB5A is required for the fusion of plasma membranes and early
CC endosomes. Contributes to the regulation of filopodia extension.
CC Required for the exosomal release of SDCBP, CD63, PDCD6IP and syndecan.
CC Regulates maturation of apoptotic cell-containing phagosomes, probably
CC downstream of DYN2 and PIK3C3. {ECO:0000250|UniProtKB:P18066,
CC ECO:0000250|UniProtKB:P20339, ECO:0000250|UniProtKB:Q9CQD1}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=GTP + H2O = GDP + H(+) + phosphate; Xref=Rhea:RHEA:19669,
CC ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:37565,
CC ChEBI:CHEBI:43474, ChEBI:CHEBI:58189; EC=3.6.5.2;
CC Evidence={ECO:0000250|UniProtKB:P20339};
CC PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:19670;
CC Evidence={ECO:0000250|UniProtKB:P20339};
CC -!- ACTIVITY REGULATION: Regulated by guanine nucleotide exchange factors
CC (GEFs) which promote the exchange of bound GDP for free GTP.
CC {ECO:0000250|UniProtKB:P18066}.
CC -!- SUBUNIT: Interacts with GDI1; this promotes dissociation from
CC membranes; phosphorylation at Ser-84 disrupts this interaction (By
CC similarity). Interacts with GDI2; phosphorylation at Ser-84 disrupts
CC the interaction (By similarity). Interacts with SGSM1 and SGSM3 (By
CC similarity). Interacts with PIK3CB. Interacts with RIN1 and GAPVD1,
CC which regulate its pathway, probably by acting as a GEF. Interacts with
CC RINL. Interacts with ALS2CL, SUN2, ZFYVE20 and RUFY1. Interacts with
CC RABEP1; one RABEP1 homodimer binds two RAB5A chains, but at opposite
CC sides of the dimer. Interacts with OCRL and INPP5F. May be a component
CC of a complex composed of RAB5A, DYN2 and PIK3C3. Does not interact with
CC the BLOC-3 complex (heterodimer of HPS1 and HPS4). Interacts with CLN5.
CC Interacts with APPL2 (By similarity). Interacts with F8A1/F8A2/F8A3 (By
CC similarity). Found in a complex with F8A1/F8A2/F8A3, HTT and RAB5A;
CC mediates the recruitment of HTT by RAB5A onto early endosomes (By
CC similarity). {ECO:0000250|UniProtKB:P18066,

CC Alternates between membrane-bound and cytosolic forms.
CC {ECO:0000250|UniProtKB:P20339}.
CC -!- PTM: Phosphorylation of Ser-84 in the switch II region by LRRK2
CC prevents the association of RAB regulatory proteins, including RAB GDP
CC dissociation inhibitors GDI1 and GDI2. {ECO:0000250|UniProtKB:P20339}.
