it is activated upstream by RalGEFs (themselves recruited by GTP-Ras or Rap1 at the membrane), by Aurora A-mediated phosphorylation at Ser194 (which relocalizes it to mitochondria to drive DRP1-dependent fission at mitosis), by a Rab10-Rlf cascade in insulin signaling, and is inactivated by the RGC1/RGC2 GAP complex downstream of Akt; through the exocyst, RALA controls polarized membrane trafficking critical for cytokinesis, neuronal polarity, synaptic plasticity, GLUT4 translocation, Wnt receptor internalization, MVB biogenesis/exosome secretion, and rapid furrow formation, while also regulating NF-κB/cyclin D1 transcription, mTORC1 engagement, and caveolae-mediated endocytosis via PLD2."},"narrative":{"mechanistic_narrative":"RALA is a Ras-related small GTPase that cycles between GDP- and GTP-bound states with intrinsically low GTPase activity, binds and hydrolyzes GTP, and is anchored to membranes via a C-terminal lipid modification [PMID:3023062, PMID:2108160, PMID:15530367]. Nucleotide cycling is controlled by dedicated regulators: RalGDS-family GEFs require membrane co-localization with GTP-Ras (or Ras-independent recruitment through beta-arrestin) to load GTP onto lipid-modified RALA [PMID:9416833, PMID:12105416], TD-60/RCC2 acts as a mitotic GEF [PMID:26158537], and the RGC1/RGC2 (RalGAP) heterodimer stimulates GTP hydrolysis under control of Akt-mediated phosphorylation [PMID:21148297]. In its GTP-bound state RALA engages a defined set of effectors through its switch regions: RLIP76/RalBP1, which couples RALA to Rac1/CDC42 GAP activity and to the AP2 endocytic machinery [PMID:7673236, PMID:7623849, PMID:10910768]; the exocyst, where Sec5 and Exo84 bind competitively at overlapping sites [PMID:14978027, PMID:15920473]; PLD1/PLD2 via a unique N-terminal region to generate phosphatidic acid [PMID:7477381, PMID:9520417]; and filamin to drive filopodium formation downstream of Cdc42 [PMID:10051605]. Through the exocyst, RALA directs polarized membrane trafficking that underlies cytokinetic furrow formation, neuronal polarity and synaptic plasticity, insulin- and feeding-stimulated GLUT4 translocation, integrin and membrane-raft delivery during migration, Wnt receptor (Frizzled-7) internalization, membrane-nanotube formation, and multivesicular-body/exosome biogenesis [PMID:11865051, PMID:17765682, PMID:18756269, PMID:19383721, PMID:20005108, PMID:26459596, PMID:30853556]. Beyond trafficking, RALA drives transcriptional and metabolic programs—relieving ZONAB repression and inducing NF-κB/cyclin D1 [PMID:11027278, PMID:15592429]—and, upon Aurora A phosphorylation at Ser194, relocalizes to mitochondria to concentrate RalBP1 and drive DRP1-dependent mitochondrial fission [PMID:19901077, PMID:21822277, PMID:38286821]. RALA is required for Ras-driven oncogenic transformation, anchorage-independent growth, and tumorigenesis, and is a target of structure-based small-molecule inhibitors [PMID:8631302, PMID:17174914,

Cooperates with EXOC2 to recruit other components of the exocyst to the early midbody (PubMed:18756269).

activity, binds and hydrolyzes GTP, and is anchored to membranes via a C-terminal lipid modification [#0, #1, #21]. Nucleotide cycling is controlled by dedicated regulators: RalGDS-family GEFs require membrane co-localization with GTP-Ras (or Ras-independent recruitment through beta-arrestin) to load GTP onto lipid-modified RALA [#7, #17], TD-60/RCC2 acts as a mitotic GEF [#41], and the RGC1/RGC2 (RalGAP) heterodimer stimulates GTP hydrolysis under control of Akt-mediated phosphorylation [#33]. In its GTP-bound state RALA engages a defined set of effectors through its switch regions: RLIP76/RalBP1, which couples RALA to Rac1/CDC42 GAP activity and to the AP2 endocytic machinery [#3, #13]; the exocyst, where Sec5 and Exo84 bind competitively at overlapping sites [#19, #23]; PLD1/PLD2 via a unique N-terminal region to generate phosphatidic acid [#4, #9]; and filamin to drive filopodium formation downstream of Cdc42 [#10]. Through the exocyst, RALA directs polarized membrane trafficking that underlies cytokinetic furrow formation, neuronal polarity and synaptic plasticity, insulin- and feeding-stimulated GLUT4 translocation, integrin and membrane-raft delivery during migration, Wnt receptor (Frizzled-7) internalization, membrane-nanotube formation, and multivesicular-body/exosome biogenesis [#18, #25, #26, #29, #32, #42, #45]. Beyond trafficking, RALA drives transcriptional and metabolic programs—relieving ZONAB repression and inducing NF-\\u03baB/cyclin D1 [#15, #20]—and, upon Aurora A phosphorylation at Ser194, relocalizes to mitochondria to concentrate RalBP1 and drive DRP1-dependent mitochondrial fission [#28, #34, #47].
