Specific localization of Rabs at intracellular membranes.
Despite over two decades of research, the mechanism of Rab targeting to specific intracellular membranes is still not completely understood. Present evidence suggests that the original hypothesis that the message for targeting resides solely in the hypervariable C-terminus is incorrect, and a second mechanism involving a GDF [GDI (guanine-nucleotide-dissociation inhibitor) displacement factor] ...
متن کاملThree new Drosophila markers of intracellular membranes.
The need for cellular markers that permit a quick and accurate evaluation of a protein's subcellular localization has increased with the surge of new data generated by the Drosophila genome project. In this report, we present three ubiquitously expressed Drosophila transgenes that expressed a green fluorescent protein variant (enhanced yellow fluorescent protein) that has been targeted to diffe...
متن کاملGiga-Ohm Seals on Intracellular Membranes: A Technique for Studying Intracellular Ion Channels in Intact Cells
A method is outlined for obtaining giga-ohm seals on intracellular membranes in intact cells. The technique employs a variant of the patch-clamp technique: a concentric electrode arrangement protects an inner patch pipette during penetration of the plasma membrane, after which a seal can be formed on an internal organelle membrane. Using this technique, successful recordings can be obtained wit...
متن کاملGαi3-Dependent Inhibition of JNK Activity on Intracellular Membranes
Heterotrimeric G-protein signaling has been shown to modulate a wide variety of intracellular signaling pathways, including the mitogen-activated protein kinase (MAPK) family. The activity of one MAPK family class, c-Jun N-terminal kinases (JNKs), has been traditionally linked to the activation of G-protein coupled receptors (GPCRs) at the plasma membrane. Using a unique set of G-protein signal...
متن کاملZonal density gradient electrophoresis of intracellular membranes of brain cortex.
Rat cerebral cortex was homogenized in a sucrose-free medium and a number of intracellular melnbrane fractions were isolated therefrom by means of differential and density-gradient centrifugation. The mitochondrial and microsomal membrane fractions, as well as the separated rough and smooth endoplasmic reticulum components of the latter, were subjected to zonal density gradient electrophoresis....
