Characterization of the RhoGAP proteins RGA-3 and RGA-4 and the centrosomal protein SAS-5 in the early "Caenorhabditis elegans" embryo [PDF]
, 2007 The Caenorhabditis elegans embryo serves as a great tool to study cell biological processes like polarization and cell divison. The first cell division is unequal and cell polarization is dependant on the Rho GTPase regulated rearrangement of the cell ...

Recruitment of AP-1 clathrin adaptors to liposomal membranes [PDF]
, 2004 Protein and membrane traffic between organelles within the endocytic and exocytic pathway is mediated most prominently by coated vesicles. These vesicles are formed by the assembly of cytosolic coat proteins onto the donor membrane, which deform it into ...

eLife, 2020 Retromer, including Vps35, Vps26, and Vps29, is a protein complex responsible for recycling proteins within the endolysosomal pathway. Although implicated in both Parkinson’s and Alzheimer’s disease, our understanding of retromer function in the adult ...

GTP Binding Assays in Arabidopsis thaliana
Bio-Protocol, 2013 Signaling through G proteins constitutes an ancient mechanism that functions in the transduction of extracellular signals into intracellular responses. Activation of a proper receptor by a stimuli leads to an exchange of GDP for GTP, the activation of G ...

alpha 2-chimaerin, a Cdc42/Rac1 regulator, is selectively expressed in the rat embryonic nervous system and is involved in neuritogenesis in N1E-115 neuroblastoma cells [PDF]
, 2001 Neuronal differentiation involves Rac and Cdc42 GTPases. alpha -Chimaerin, a Rac/Cdc42 regulator, occurs as alpha 1- and alternatively spliced Src homology 2 (SH2) domain-containing alpha 2-isoforms. alpha 2-chimaerin mRNA was highly expressed in the rat

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane
FEBS Letters, EarlyView.Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.

An Outlook on the Localisation and Structure-Function Relationships of R Proteins in Solanum [PDF]
, 2009 The co-evolution of plants and plant-pathogens shaped a multi-layered defence system in plants, in which Resistance proteins (R proteins) play a significant role.

FEBS Letters, EarlyView.This study reveals that the small GTPase Rab14 is necessary for human papillomavirus (HPV) infection and plays an essential role in the transport of virions to the trans‐Golgi network (TGN). HPV in the early endosome (EE), which harbors GTP‐bound Rab14, is transported to the TGN through the switch of Rab14 from its GTP‐bound to GDP‐bound form.

Analysis of Rho GTPase signalling pathways regulating epithelial morphogenesis [PDF]
, 2010 Rho GTPases are molecular switches controlling many aspects of cell behaviour, including cell cycle progression, cell division, migration and morphology. The activity of Rho proteins is regulated by conformational changes induced by binding of guanine
