Integrative Transcriptomic and Phosphoproteomic Analysis Reveals Key Components of the SnRK1 Signaling Network in Rice

open access: yesPlant Direct, Volume 9, Issue 11, November 2025.
ABSTRACT SnRK1 is an evolutionarily conserved protein kinase belonging to the SNF1/AMPK family of protein kinases that is central to adjusting growth in response to the energy status. Numerous studies have shown adaptive and developmental roles of SnRK1, but the understanding of the SnRK1 signaling network in monocots is limited.

Turing instabilities in a mathematical model for signaling networks

open access: yes, 2011
GTPase molecules are important regulators in cells that continuously run through an activation/deactivation and membrane-attachment/membrane-detachment cycle. Activated GTPase is able to localize in parts of the membranes and to induce cell polarity.

Nucleotide exchange factor Rab3GEP requires DENN and non-DENN elements for activation and targeting of Rab27a. [PDF]

open access: yes, 2019
Rab GTPases are compartment-specific molecular switches that regulate intracellular vesicular transport in eukaryotes. GDP/GTP exchange factors (GEFs) control Rab activation, and current models propose that localised and regulated GEF activity is ...

Variants in genes encoding small GTPases and association with epithelial ovarian cancer susceptibility.

open access: yesPLoS ONE, 2018
Epithelial ovarian cancer (EOC) is the fifth leading cause of cancer mortality in American women. Normal ovarian physiology is intricately connected to small GTP binding proteins of the Ras superfamily (Ras, Rho, Rab, Arf, and Ran) which govern processes

Mining Alzheimer's Interactomes, Macromolecular Complexes and Pathways for Drug Discovery

open access: yesPROTEOMICS, Volume 25, Issue 21-22, Page 102-150, November 2025.
ABSTRACT Alzheimer's disease (AD) is a progressive neurodegenerative disorder that leads to dementia. Many cases are diagnosed annually and there is no currently available cure. Understanding the underlying disease biology of AD through the study of molecular networks, particularly by mapping clinical variants to tissue‐specific interactomes and ...

Phosphoinositide-dependent regulation of VAN3 ARF-GAP localization and activity essential for vascular tissue continuity in plants [PDF]

open access: yes, 2009
ACAP-type ARF GTPase activating proteins (ARF-GAPs) regulate multiple cellular processes, including endocytosis, secretion, phagocytosis, cell adhesion and cell migration.

New Mechanisms for Regulation of Intracellular Collagen Degradation in Fibrotic Lesions of Periodontal Tissues

open access: yesThe FASEB Journal, Volume 39, Issue 20, 31 October 2025.
Drug‐induced gingival overgrowth involves dysregulation of intracellular collagen degradation. The mechanisms that are involved in the regulation of lysosomal collagenolytic activity are poorly understood. Here, we focus on how cathepsins, Rabs, and V‐ATPases regulate intracellular collagen degradation and, in particular, the vesicular trafficking and ...

Activation of Lysosomal Retrograde Transport Triggers TPC1‐IP3R1 Ca2+ Crosstalk at Lysosome‐ER MCSs Leading to Lethal Depleting of ER Calcium

open access: yesAdvanced Science, Volume 12, Issue 39, October 20, 2025.
The flavonoid compound LW‐213 exerts its antitumor effects through a novel mechanism involving lysosomal‐ER calcium regulation. Specifically, LW‐213 binds to LIMP2, which induces perinuclear clustering of lysosomes and facilitates calcium‐mediated lysosome‐ER interactions.

Rab8a and Rab8b are essential for several apical transport pathways but insufficient for ciliogenesis [PDF]

open access: yes, 2013
The small GTP-binding protein Rab8 is known to play an essential role in intracellular transport and cilia formation. We have previously demonstrated that Rab8a is required for localising apical markers in various organisms.
