26977884 RAB1B localization to the Golgi.
25970785 RAB1B acts as a metastasis suppressor in triple-negative breast cancer by regulating the TGF-beta/SMAD signaling pathway and RAB1B may serve as a biomarker of prognosis and response to anti-tumor therapeutics for patients with triple-negative breast cancer.
23325787 Our results show, for the first time, that changes in Rab1b levels modulate gene transcription and strongly suggest that a Rab1b increase is required to elicit a secretory response.
23288104 The crystal structure of the Rab1b-LepB complex.
23236136 The detailed molecular reaction mechanism of a complex between human Rab and RabGAP at the highest possible spatiotemporal resolution and in atomic detail, is described.
23188820 results indicate that the cellular localization of MTMR6 is regulated by Rab1B in the early secretory and autophagic pathways
22260459 Overexpression of TBC1D20, RAB1A, or RAB1B results in abnormal HIV-1 gp41 migration, suggesting that a precise regulation of the RAB1/TBC1D20 axis is necessary for proper HIV-1 gp41 processing
21680502 Rab1a/b and Rab43, are important for herpes simplex virus 1 virion assembly
21093099 Rab1b is a key regulatory component of COPII dynamics and function.
20980813 Antibacterial autophagy occurs at omegasomes and reveal that the Rab1 GTPase plays a crucial role in mammalian autophagy.
20164217 The authors demonstrate that Rab1b-activated GBF1 and ARF1 are involved in Ebolavirus virion formation, suggesting that both the COPII and COPI transport systems play a role in Ebolavirus VP40-mediated particle formation.
18187620 Knockdown of RAB1B, member RAS oncogene family (RAB1B) by siRNA inhibits HIV-1 replication in HeLa-derived TZM-bl cells
17947549 findings show that SidM from Legionella pneumophila could act as both a GDP-GTP exchange factor and GDP-dissociation inhibitor-displacement factor (GDF) for Rab1
17429068 These data support a model where Rab1b-GTP induces GBF1 recruitment at the ERES interface and at the Golgi complex where it is required for COPII/COPI exchange or COPI vesicle formation, respectively.
