Interactions between lipids and voltage sensor paddles detected with tarantula toxins

Milescu, Mirela Bosmans, Frank Lee, Seungkyu Alabi, AbdulRasheed A Kim, Jae Il Swartz, Kenton J

Voltage-activated ion channels open and close in response to changes in voltage, a property that is essential for generating nerve impulses. Studies on voltage-activated potassium (Kv) channels show that voltage-sensor activation is sensitive to the composition of lipids in the surrounding membrane. Here we explore the interaction of lipids with S1...

Polyelectrolyte-mediated adsorption of amelogenin monomers and nanospheres forming mono- or multilayers

Gergely, Csilla Szalontai, Balazs Moradian-Oldak, Janet Cuisinier, Frederic J. G.

We have applied optical waveguide lightmode spectroscopy combined with streaming potential measurements and Fourier-transformed infrared spectroscopy to investigate adsorption of amelogenin nanospheres onto polyelectrolytes. The long-term objective was to better understand the chemical nature of these assemblies and to gain further insight into the...

The Abscisic Acid–Related SNARE Homolog NtSyr1 Contributes to Secretion and Growth: Evidence from Competition with Its C...

Geelen, Danny Leyman, Barbara Batoko, Henri Di Sansabastiano, Gian-Pietro Moore, Ian Blatt, Michael R.

Syntaxins and other SNARE proteins are crucial for intracellular vesicle trafficking, fusion, and secretion. Previously, we isolated the syntaxin-related protein NtSyr1 (NtSyp121) from tobacco in a screen for abscisic acid–related signaling elements, demonstrating its role in determining the abscisic acid sensitivity of K(+) and Cl(−) channels in s...
