Human RAB8A, Member RAS Oncogene Family (RAB8A) interaction partners

1. We demonstrated that deficiency of GCase(GBA1) leads to a reduction of C18-ceramide species and altered intracellular localization of Rab8a, a small GTPase implicated in secretory autophagy, that contributed to impaired secretion of a-synuclein and accumulation of intracellular a-synuclein.

7. Ectopic expression of an N-terminal-truncated ARHGEF10 mutant led to the generation of large vesicle-like structures containing both Rab6 and Rab8.

8. report the design of a bioavailable StRIP3 analogue that harbors two hydrophobic cross-links and exhibits increased binding affinity, combined with robust cellular uptake and extremely high proteolytic stability. Localization experiments reveal that this double-stapled peptide and its target protein Rab8a accumulate in the same cellular compartments

9. knockdown of another Parkinson's disease (PD) gene, LRRK2, which phosphorylates Rab8a, similarly impairs retromer trafficking, secretory autophagy and Golgi-derived vesicle secretion, thus demonstrating converging roles of two PD genes TMEM230 and LRRK2 on Rab8a function, and suggesting that retromer and secretory dysfunction play an important role in PD pathogenesis.

10. Rab8 can induce Rac1- and Tiam1-dependent cortical actin polymerization and focal adhesion disassembly through the proteases MT1-MMP and calpain, and Rho-GTPase-dependent mechanisms

11. Data demonstrate that EHBP1L1 links Rab8 and the Bin1-dynamin complex, which generates membrane curvature and excises the vesicle at the endocytic recycling compartment for apical transport.

12. Further exploration of the NINL-associated interactome identifies MICAL3, a protein known to interact with Rab8 and to play an important role in vesicle docking and fusion.

13. The small GTPase Rab8 interacts with VAMP-3 to regulate the delivery of recycling T-cell receptors to the immune synapse.

14. the role of Rabin8 (a mammalian ortholog of Sec2p) with Rab8-nucleotide-exchange factor activity in autophagy in mammalian cells, was examined.

15. DLC3 is recruited to Rab8-positive membrane tubules and is required for the integrity of the Rab8 and Golgi compartments.

16. Rab8A GTPase Ser(111) phosphorylation is not directly regulated by PINK1 in vitro and demonstrate in cells the time course of Ser(111) phosphorylation of Rab8A, 8B and 13 is markedly delayed compared to phosphorylation of Parkin at Ser(65).

17. Intercellular transfer of transferrin receptor by a contact-, Rab8-dependent mechanism involving tunneling nanotubes.

18. High expression of RAB8A is associated with endometrial cancer.

20. Rab8a and Drebrin E act as key proteins in the regulation of apical trafficking in intestinal epithelial cells.

Zebrafish RAB8A, Member RAS Oncogene Family (RAB8A) interaction partners

1. While localization of the small GTPase Rab8a, which plays an important role in basal body docking, appears unaffected in talpid3-/- photoreceptors, overexpression of constitutively active Rab8a rescues outer segment formation, indicating that the role of Ta3 in early ciliogenesis lies upstream of Rab8a activation in photoreceptors.

2. Results support participation of Rab8 in OCV trafficking and identify a novel role for the TZ protein Cc2d2a in fusion of incoming ciliary-directed vesicles, through organization of the vesicle fusion machinery at the periciliary membrane.

3. Cc2d2a, localized at the photoreceptor connecting cilium/transition zone, facilitates protein transport through a role in Rab8-dependent vesicle trafficking and fusion.

4. Data show that elipsa encodes a coiled-coil polypeptide that localizes to cilia, and that it interacts genetically with Rabaptin5, a well-studied regulator of endocytosis, which in turn interacts with Rab8, a small GTPase, known to localize to cilia.

Mouse (Murine) RAB8A, Member RAS Oncogene Family (RAB8A) interaction partners

1. Disruption of Rab8a and Rab11a causes formation of basolateral microvilli in neonatal enteropathy.

2. The small GTPase Rab8a regulates lipid uptake and storage in skeletal muscle.

3. Rab8a and Rab11a Are Dispensable for Rhodopsin Transport in Mouse Photoreceptors

4. With CRISPR/Cas9-mediated gene editing to stably knock out and recover Rab8a in macrophage cell lines, this study matches Akt signaling profiles with cytokine outputs, confirming that Rab8a is a novel regulator of the Akt/mammalian target of rapamycin (mTOR) pathway downstream of multiple Toll-like Receptors.

5. these results indicate an indispensable role for Rab8A in insulin-regulated GLUT4 trafficking in C2C12 cells.

6. Results highlight a novel role of Rab8, downstream of IFT20, in the pathway that regulates T cell receptor (TCR) recycling, through recruiting VAMP-3 and promoting the fusion with the synaptic membrane of endosomes carrying TCR cargoes.

7. Data demonstrate that EHBP1L1 links Rab8 and the Bin1-dynamin complex, which generates membrane curvature and excises the vesicle at the endocytic recycling compartment for apical transport.

8. The small GTPase Rab8 interacts with VAMP-3 to regulate the delivery of recycling T-cell receptors to the immune synapse.

9. Rab8a thus controls Wnt delivery in producing cells and is crucial for Paneth cell maturation.

10. Rab8a acts as an activator of Fsp27-mediated LD fusion and growth.

11. Simultaneous loss of Rab8a and Rab8b has little effect on ciliogenesis, whereas additional loss of Rab10 greatly affects ciliogenesis.

18. GLUT4 vesicle recruitment and fusion are differentially regulated by Rac, AS160, and Rab8A in muscle cells.

19. Ahi1 is required for Rab8a localization, ciliogenesis and vesicle trafficking.
