Regulation of CAMP Compartmentation by Membrane Microdomains [PDF]

Biophysical Journal, 2013
The role of different membrane domains in the compartmentation of cAMP signaling was investigated using the FRET-based biosensor Epac2-camps. The MyrPalm sequence from Lyn kinase and the CAAX sequence from Rho GTPase were used to target this probe to lipid raft (Epac2-MyrPalm) or non-lipid raft (Epac2-CAAX) domains, respectively.

Insulin Signaling in Microdomains of the Plasma Membrane [PDF]

Traffic, 2003
Although the effects of insulin on glucose and lipid metabolism are well documented, gaps remain in our understanding of the precise molecular mechanisms of signal transduction. Recent evidence suggests that compartmentalization of signaling molecules and metabolic enzymes may explain the unique cellular effects of the hormone.

Nanoclustering as a dominant feature of plasma membrane organization [PDF]

, 2014
Early studies have revealed that some mammalian plasma membrane proteins exist in small nanoclusters. The advent of super-resolution microscopy has corroborated and extended this picture, and led to the suggestion that many, if not most, membrane ...

Role of mitochondrial raft-like microdomains in the regulation of cell apoptosis [PDF]

, 2015
Lipid rafts are envisaged as lateral assemblies of specific lipids and proteins that dissociate and associate rapidly and form functional clusters in cell membranes.

Steady-state modulation of voltage-gated K+ channels in rat arterial smooth muscle by cyclic AMP-dependent protein kinase and protein phosphatase 2B [PDF]

, 2015
Voltage-gated potassium channels (Kv) are important regulators of membrane potential in vascular smooth muscle cells, which is integral to controlling intracellular Ca2+ concentration and regulating vascular tone. Previous work indicates that Kv channels

Sphingolipids: membrane microdomains in brain development, function and neurological diseases [PDF]

Open Biology, 2017
Sphingolipids are highly enriched in the nervous system where they are pivotal constituents of the plasma membranes and are important for proper brain development and functions. Sphingolipids are not merely structural elements, but are also recognized as

T cell Ca2+ microdomains through the lens of computational modeling

Frontiers in Immunology, 2023
Cellular Ca2+ signaling is highly organized in time and space. Locally restricted and short-lived regions of Ca2+ increase, called Ca2+ microdomains, constitute building blocks that are differentially arranged to create cellular Ca2+ signatures ...

Membrane microdomains and insulin resistance [PDF]

FEBS Letters, 2009
A new concept, that “metabolic disorders, such as type 2 diabetes, are membrane microdomain disorders caused by aberrant expression of gangliosides”, has arisen. By examining this working hypothesis, we demonstrate the molecular pathogenesis of type 2 diabetes and insulin resistance focusing on the interaction between insulin receptor and gangliosides ...

Glycosphingolipid GM3 is localized in both exoplasmic and cytoplasmic leaflets of Plasmodium falciparum malaria parasite plasma membrane

Scientific Reports, 2021
Lipid rafts, sterol-rich and sphingolipid-rich microdomains on the plasma membrane are important in processes like cell signaling, adhesion, and protein and lipid transport.

Multiple Kv1.5 targeting to membrane surface microdomains [PDF]

Journal of Cellular Physiology, 2008
AbstractSurface expression of voltage‐dependent K+ channels (Kv) has a pivotal role in leukocyte physiology. Although little is known about the physiological role of lipid rafts, these microdomains concentrate signaling molecules and their ion channel substrates. Kv1.3 associates with Kv1.5 to form functional channels in macrophages.
