ProteomicsRAB GTPase proximity interactome
RAB GTPases represent the most abundant family of small GTPases and regulate multiple aspects of membrane trafficking events, from cargo sorting to vesicle budding, transport, docking, and fusion. To control these processes, RABs are tightly regulated by guanine exchange factors (GEFs) and GTPase-ac...

ProteomicsLocal RNA translation controls cell migration and Rab GTPase function
Numerous RNAs exhibit specific distribution patterns in mammalian cells. However, the functional and mechanistic consequences are relatively unknown. We investigate here the functional role of RNA localization at cellular protrusions of mesenchymal migrating cells, using as a model the RAB13 RNA, wh...

ProteomicsComparative proteomic identification of Rab GTPase interactors in Arabidopsis
Rab GTPases are key spatio-temporal regulators of endomembrane trafficking and endomembrane compartment identity across eukaryotes. This therefore makes them ideal targets for study of endomembrane compartment and trafficking pathway composition. In plants, few definitive interactors of Rab GTPases ...

GenomicsNKX3-1, a Novel Transcriptional Factor of AR, Promotes Prostate Cancer Cell Survival via RAB3B GTPase-mediated protein trafficking
Androgen receptor (AR) orchestrates an intricate transcriptional regulatory network that governs prostate cancer initiation, development and progression. To understand this network in detail, we generated genome-wide maps of AR occupancy by ChIP-seq in LNCaP cells. We found NKX3-1, an androgen-depen...

ProteomicsInteractions between Transport Protein Particle (TRAPP) complexes and Rab GTPases in Arabidopsis
The Transport Protein Particle II (TRAPPII) is essential for exocytosis, endocytosis, protein sorting and cytokinesis. In spite of a considerable understanding of its biological role, little is known about Arabidopsis TRAPPII complex topology and molecular function. In this study, independent proteo...

ProteomicsRab5a-VPS34 unnatural amino acid mediated crosslinking
The small GTPase Rab5 has an essential role in sorting vesicles arriving to and leaving the early endosome. One key function of Rab5 in this process is the activation of the primordial phosphatidylinositol 3-kinase VPS34, a lipid kinase that phosphorylates phosphatidylinositol (PI) to generate PI3P....

TranscriptomicsGenome-wide transcriptome profiling of SK-Mel-28, UACC-62 and HCT-116 cells stably expressing scrambled shRNA and RAB7 shRNA
Purpose: Assess the transcriptional changes induced upon RAB7 knock-down in melanoma (SK-Mel-28 and UACC-62) and in colon cancer (HCT-116) cell lines. Methods: mRNA profiles of tumor cell lines (SK-Mel-28, UACC-62, HCT-116) stably expressing scrambled shRNA or RAB7 shRNA (harvested at day 3 after le...

TranscriptomicsDistinctive responses to nitrogen starvation in the dominant active mutants of the fission yeast Rheb GTPase.
Rheb, a ras-like small GTPase conserved from human to yeast, controls Tor kinase and plays a central role in regulation of cell growth depending on extracellular conditions. Fission yeast Rheb regulates amino acid uptake as well as response to nitrogen starvation. In this study we generated two muta...

ProteomicsUsing HDX-MS to study Rab and Ral covalently bound to MRTX1257
Here we use HDX to study covalently modified Rab1a and RalA in both their apo states and bound to MRTX1257 to see how this compound affects the overall secondary structure of the proteins.
