Rho GTPases and signaling networks [PDF]
, 1997 The Rho GTPases form a subgroup of the Ras superfamily of 20- to 30-kD GTP-binding proteins that have been shown to regulate a wide spectrum of cellular functions. These proteins are ubiquitously expressed across the species, from yeast to man.

Cell size, mechanical tension, and GTPase signaling in the Single Cell [PDF]
arXiv, 2019 Cell polarization requires redistribution of specific proteins to the nascent front and back of a eukarytotic cell. Among these proteins are Rac and Rho, members of the small GTPase family that regulate the actin cytoskeleton. Rac promotes actin assembly and protrusion of the front edge, whereas Rho activates myosin-driven contraction at the back ...

Gem-induced cytoskeleton remodeling increases cellular migration of HTLV-1-infected cells, formation of infected-to-target T-cell conjugates and viral transmission [PDF]
, 2013 Efficient HTLV-1 viral transmission occurs through cell-to-cell contacts. The Tax viral transcriptional activator protein facilitates this process. Using a comparative transcriptomic analysis, we recently identified a series of genes up-regulated in HTLV-

The Journal of Physiology, EarlyView.Abstract figure legend The volume‐regulated anion channel (VRAC), composed of leucine‐rich repeat‐containing 8 (LRRC8) proteins, serves both canonical and non‐canonical functions in vertebrate cells. The canonical function of this channel relates to its original description, which is homeostatic regulation of cell volume in response to hypotonic ...

The Journal of Physiology, EarlyView.Abstract figure legend During development, Intersectin‐1 (Itsn1) translocates near voltage‐gated calcium channels (VGCCs) to enhance Ca2+‐dependent replenishment of readily releasable synaptic vesicles (SVs). In the presynaptic terminal, SVs undergo a cycle involving formation (step 1), docking (step 2), exocytosis (step 3), endocytosis (step 4) and ...

Protein Inference and Protein Quantification: Two Sides of the Same Coin [PDF]
arXiv, 2012 Motivation: In mass spectrometry-based shotgun proteomics, protein quantification and protein identification are two major computational problems. To quantify the protein abundance, a list of proteins must be firstly inferred from the sample. Then the relative or absolute protein abundance is estimated with quantification methods, such as spectral ...

Proapoptotic and antiinvasive activity of Rac1 small molecule inhibitors on malignant glioma cells [PDF]
, 2014 Malignant gliomas are characterized by an intrinsic ability to invade diffusely throughout the normal brain tissue. This feature contributes mainly to the failure of existing therapies. Deregulation of small GTPases signaling, in particular Rac1 activity,

Sphingosine‐1‐phosphate activates LRRC8 volume‐regulated anion channels through Gβγ signalling
The Journal of Physiology, EarlyView.Abstract figure legend Sphingosine‐1‐phosphate (S1P) binds to Gi protein‐coupled receptor S1PR1. Upon S1PR1 activation, Gβγ is released from the Gαi‐Gβγ heterotrimer, allowing it to recruit phospholipase Cβ (PLCβ) to the plasma membrane. PLCβ cleaves phosphatidylinositol‐4,5‐bisphosphate (PIP2) into inositol trisphosphate (IP3) and diacylglycerol (DAG).

Phenotypic Expansion of Knobloch Syndrome Type 2 in an Individual With a De Novo PAK2 Variant
American Journal of Medical Genetics Part A, Volume 197, Issue 6, June 2025.ABSTRACT P21‐activated kinase 2 (PAK2) is a serine/threonine kinase essential for a variety of cellular processes including signal transduction, cellular survival, proliferation, and migration. A recent report proposed monoallelic PAK2 variants cause Knobloch syndrome type 2 (KNO2)—a developmental disorder primarily characterized by ocular anomalies ...
