Nucleophosmin1 is a negative regulator of the small GTPase Rac1. [PDF]
PLoS ONE, 2013 The Rac1 GTPase is a critical regulator of cytoskeletal dynamics and controls many biological processes, such as cell migration, cell-cell contacts, cellular growth and cell division.

Disrupting the ciliary gradient of active Arl3 affects rod photoreceptor nuclear migration
eLife, 2023 The small GTPase Arl3 is important for the enrichment of lipidated proteins to primary cilia, including the outer segment of photoreceptors. Human mutations in the small GTPase Arl3 cause both autosomal recessive and dominant inherited retinal ...

Small GTPase patterning: How to stabilise cluster coexistence.
PLoS ONE, 2019 Many biological processes have to occur at specific locations on the cell membrane. These locations are often specified by the localised activity of small GTPase proteins.

Spatial and temporal dynamics of RhoA activities of single breast tumor cells in a 3D environment revealed by a machine learning-assisted FRET technique [PDF]
, 2021 One of the hallmarks of cancer cells is their exceptional ability to migrate within the extracellular matrix (ECM) for gaining access to the circulatory system, a critical step of cancer metastasis. RhoA, a small GTPase, is known to be a key molecular switch that toggles between actomyosin contractility and lamellipodial protrusion during cell ...

A mathematical model coupling polarity signaling to cell adhesion explains diverse cell migration patterns [PDF]
, 2016 Cells crawling through tissues migrate inside a complex fibrous environment called the extracellular matrix (ECM), which provides signals regulating motility. Here we investigate one such well-known pathway, involving mutually antagonistic signalling molecules (small GTPases Rac and Rho) that control the protrusion and contraction of the cell edges ...

Beyond the GTP‐cap: Elucidating the molecular mechanisms of microtubule catastrophe
BioEssays, Volume 45, Issue 1, January 2023., 2023 Microtubule dynamics are essential for myriad cellular processes. The switching between microtubule growth and shrinkage is traditionally explained by the loss of a protective “cap” of GTP‐bound tubulin subunits from the growing microtubule end. New research shows that features beyond the nucleotide content at the growing end impact microtubule ...

Switch-like enhancement of epithelial-mesenchymal transition by YAP through feedback regulation of WT1 and small Rho-family GTPases [PDF]
, 2017 Collective cell migration is a hallmark of developmental and patho-physiological states, including wound healing and invasive cancer growth. The integrity of the expanding epithelial sheets can be influenced by extracellular cues, including cell-cell and cell-matrix interactions.

Cancer Communications, Volume 42, Issue 12, Page 1367-1386, December 2022., 2022 Abstract Background Neuroendocrine carcinomas of the gastrointestinal tract (GI‐NECs) remain a disease of grim prognosis with limited therapeutic options. Their molecular characteristics are still undefined. This study aimed to explore the underlying genetic basis and heterogeneity of GI‐NECs.
