Rab32 restriction of intracellular bacterial pathogens.
Solano-Collado V, Rofe A, Spanò S. Solano-Collado V, et al. Small GTPases. 2018 May 4;9(3):216-223. doi: 10.1080/21541248.2016.1219207. Epub 2016 Sep 20. Small GTPases. 2018. PMID: 27645564 Free PMC article. Review.
Rab32 has also been shown to control infection by Listeria monocytogenes, another medically relevant intracellular pathogen. In addition, genetic evidence indicate a possible role of Rab32 in controlling leprosy, a disease caused by Mycobacterium leprae in humans, s …

Rab32 subfamily small GTPases: pleiotropic Rabs in endosomal trafficking.
Ohbayashi N, Fukuda M, Kanaho Y. Ohbayashi N, et al. J Biochem. 2017 Aug 1;162(2):65-71. doi: 10.1093/jb/mvx027. J Biochem. 2017. PMID: 28430987 Review.
During the past decade, our understanding of the functions of mammalian Rab32 subfamily members (Rab32 and Rab38) have deepened, especially on the biogenesis of lysosome-related organelles, such as melanosomes, and the protection mechanisms against several pathogeni …

Rab32/38-Dependent and -Independent Transport of Tyrosinase to Melanosomes in B16-F1 Melanoma Cells.
Nishizawa A, Maruta Y, Fukuda M. Nishizawa A, et al. Int J Mol Sci. 2022 Nov 16;23(22):14144. doi: 10.3390/ijms232214144. Int J Mol Sci. 2022. PMID: 36430618 Free PMC article.
In this study, we established knockout B16-F1 cells for each of several key factors in melanogenesis, i.e., tyrosinase (Tyr), Hps4, Rab27A, and Rab32.Rab38 (Rab32/38), and then compared their phenotypes with the phenotypes of corresponding mutant mouse melanocyte ce …

Rab32 uses its effector reticulon 3L to trigger autophagic degradation of mitochondria-associated membrane (MAM) proteins.
Herrera-Cruz MS, Yap MC, Tahbaz N, Phillips K, Thomas L, Thomas G, Simmen T. Herrera-Cruz MS, et al. Biol Direct. 2021 Nov 7;16(1):22. doi: 10.1186/s13062-021-00311-9. Biol Direct. 2021. PMID: 34743744 Free PMC article.
BACKGROUND: Rab32 is a small GTPase associated with multiple organelles but is particularly enriched at the endoplasmic reticulum (ER). ...We also identified the long isoform of reticulon-3 (RTN3L), a known ER-phagy receptor, as a Rab32 effector. CONCLUSIONS: Rab …

Rab32/38 and the xenophagic restriction of intracellular bacteria replication.
Tang BL. Tang BL. Microbes Infect. 2016 Oct;18(10):595-603. doi: 10.1016/j.micinf.2016.05.006. Epub 2016 May 30. Microbes Infect. 2016. PMID: 27256464 Review.
Recent findings have implicated a key intracellular bacterial restriction/containment function for Rab32/38 in Salmonella species in macrophages and Listeria monocytogenes in dendritic cells. Rab32/38 aids the phagolysosome maturation, and mediates a parallel xenoph …

Proteolysis of Rab32 by Salmonella GtgE induces an inactive GTPase conformation.
Savitskiy S, Wachtel R, Pourjafar-Dehkordi D, Kang HS, Trauschke V, Lamb DC, Sattler M, Zacharias M, Itzen A. Savitskiy S, et al. iScience. 2020 Dec 15;24(1):101940. doi: 10.1016/j.isci.2020.101940. eCollection 2021 Jan 22. iScience. 2020. PMID: 33426511 Free PMC article.
Cleaved Rab32 maintains its ability to interact with the GDP dissociation inhibitor (GDI). Interestingly, the Rab32 cleavage enables GDI binding also with an active GTP-bound Rab32 in vitro. ...

The Rab32/BLOC-3-dependent pathway mediates host defense against different pathogens in human macrophages.
Baldassarre M, Solano-Collado V, Balci A, Colamarino RA, Dambuza IM, Reid DM, Wilson HM, Brown GD, Mukhopadhyay S, Dougan G, Spanò S. Baldassarre M, et al. Sci Adv. 2021 Jan 15;7(3):eabb1795. doi: 10.1126/sciadv.abb1795. Print 2021 Jan. Sci Adv. 2021. PMID: 33523895 Free PMC article.
To survive in human macrophages, Salmonella Typhi actively counteracts the Rab32/BLOC-3 pathway through its Salmonella pathogenicity island-1-encoded type III secretion system. These findings demonstrate that the Rab32/BLOC-3 pathway is a novel and universal host-de …

The small GTPase Rab32 resides on lysosomes to regulate mTORC1 signaling.
Drizyte-Miller K, Chen J, Cao H, Schott MB, McNiven MA. Drizyte-Miller K, et al. J Cell Sci. 2020 Jun 11;133(11):jcs236661. doi: 10.1242/jcs.236661. J Cell Sci. 2020. PMID: 32295849 Free PMC article.
In this study, we find that Rab32 associates with lysosomes and regulates proliferation and cell size of Hep3B hepatoma and HeLa cells. ...Consistent with inhibited mTORC1, an increase in nuclear TFEB localization and lysosome biogenesis is also observed in Rab32-de …

Hepatitis C Virus-Induced Rab32 Aggregation and Its Implications for Virion Assembly.
Pham TM, Tran SC, Lim YS, Hwang SB. Pham TM, et al. J Virol. 2017 Jan 18;91(3):e01662-16. doi: 10.1128/JVI.01662-16. Print 2017 Feb 1. J Virol. 2017. PMID: 27852857 Free PMC article.
In this study, we demonstrated that both mRNA and protein levels of Rab32 were increased in HCV-infected cells. Furthermore, we showed that HCV infection converted the predominantly expressed GTP-bound Rab32 to GDP-bound Rab32, contributing to the aggregation …

The BLOC-3 complex is comprised of the two sub-units HPS1 and HPS4 and exhibits guanine-nucleotide exchange factor (GEF) activity to Rab32. In melanocytes, Rab9 has been shown to interact with HPS4 and RUTBC1, a Rab32 GTPase activating (GAP) protein, and regulate th …
