Vesicular traffic in polarized epithelial cells : identification and characterization of general and epithelial specific factors [PDF]

, 1994
Polarized epithelial cells are differentiated into apical and basolateral plasma membrane domains separated by tight junctions. The apical cell surface usually faces the external milieu, the basolateral domain provides cell-cell and cell-substratum ...

Pea G-protein γ subunits: Unlocking their potential in physiological stress and mycorrhizal mediated nutrient sensing

Current Plant Biology
Heterotrimeric GTP-binding proteins or G-proteins are pivotal players in the intricate signaling cascades of plant cells, operating through their binding to guanine nucleotides.

Small GTP Binding Proteins and the Control of Phagocytic Uptake

, 2005
Phagocytosis is a conserved cellular process in Eukaryotes. A multi-step process, it involves the recognition of paniculate material, e.g., microbes and apoptotic cells, their F-actin-driven engulfment and the subsequent destruction of the phagocytized ...

Cloning and characterisation of genes determining pod morphology in pea [PDF]

, 1994
Genes expressed in developing pea pods were isolated as cDNAs by differential screening techniques. The cDNAs were characterised by DNA sequencing and expression studies were used to investigate the role of isolated cDNAs in pod development.

Ectopic A-lattice seams destabilize microtubules [PDF]

, 2014
Natural microtubules typically include one A-lattice seam within an otherwise helically symmetric B-lattice tube. It is currently unclear how A-lattice seams influence microtubule dynamic instability.

The GDP-GTP exchange factor collybistin: an essential determinant of neuronal gephyrin clustering [PDF]

, 2004
Glycine receptors (GlyRs) and specific subtypes of GABA(A) receptors are clustered at synapses by the multidomain protein gephyrin, which in turn is translocated to the cell membrane by the GDP-GTP exchange factor collybistin.

Targeted Quantitative Profiling of GTP-Binding Proteins in Cancer Cells Using Isotope-Coded GTP Probes [PDF]

, 2018
GTP-binding proteins play important roles in many essential biological processes, including cell signaling, trafficking, and protein synthesis. To assess quantitatively these proteins at the whole proteome level, we developed a high-throughput targeted ...

Reconstitution of receptors and GTP-binding regulatory proteins (G Proteins) in Sf9 Cells: a direct evaluation of selectivity in receptor.G protein coupling

, 1997
The selectivity in coupling of various receptors to GTP-binding regulatory proteins (G proteins) was examined directly by a novel assay entailing the use of proteins overexpressed in Spodoptera frugiperda (Sf9) cells.

The GAPs, GEFs, and GDIs of heterotrimeric G-protein alpha subunits

International Journal of Biological Sciences, 2005
The heterotrimeric G-protein alpha subunit has long been considered a bimodal, GTP-hydrolyzing switch controlling the duration of signal transduction by seven-transmembrane domain (7TM) cell-surface receptors.

Aluminium fluoride and magnesium, activators of heterotrimeric GTP-binding proteins, affect high-affinity binding of the fungal toxin fusicoccin to the fusicoccin-binding protein in oat root plasma membranes.

, 1994
The fusicoccin-binding protein was solubilised from purified oat root plasma membranes. The solubilised protein retained full binding activity, provided that protease inhibitors were included.
