Sugar I, Sealfon S
J Phys Chem B
. 2009 Jul;
113(31):10946-56.
PMID: 19601596
An autocrine/paracrine signaling model in epithelial layers is described. The axially symmetric model of the epithelial layer explicitly considers the microvilli of the epithelial cells and the gaps between nearest...

J Biol Chem
. 2009 Mar;
284(20):13620-13628.
PMID: 19270338
Glycolipid transfer proteins (GLTPs) are small, soluble proteins that selectively accelerate the intermembrane transfer of glycolipids. The GLTP fold is conformationally unique among lipid binding/transfer proteins and serves as the...

J Phys Chem B
. 2008 Aug;
112(37):11631-42.
PMID: 18729402
It has been shown on model and biological systems that membrane clusters can affect in-plane membrane reactions and can control biochemical reaction cascades. Clusters of two-component phospholipid bilayers have been...

J Phys Chem B
. 2007 Apr;
111(19):5180-92.
PMID: 17441759
Here we use the excitation generalized polarization (GPex) of 6-lauroyl-2-(dimethylamino)naphthalene (Laurdan) fluorescence in fluid cholesterol/1-palmitoyl-2-oleoyl-l-alpha-phosphatidylcholine large unilamellar vesicles to explore the experimental conditions that would be required in order to...

PMID: 17394303
Two models have been developed to describe the adsorption of a model peripheral protein, colipase, to phospholipid/diacylglycerol (PL/DG) monolayers. One model is applicable at monolayer collapse pressure and at any...

109(15):7373-86.
PMID: 16851844
Lateral diffusion of membrane components makes possible any in-plane membrane reaction and has a key role in signaling in cell membranes. In this report the equilibrium lateral diffusion of intrinsic...

Biochemistry
. 2004 Feb;
43(8):2159-66.
PMID: 14979712
Here, the interplay between membrane cholesterol lateral organization and the activity of membrane surface-acting enzymes was addressed using soil bacteria cholesterol oxidase (COD) as a model. Specifically, the effect of...

PMID: 12324404
In this paper a two-state, two-component, Ising-type model is used to simulate the lateral distribution of the components and gel/fluid state acyl chains in dimyristoylphosphatidylcholine/distearoylphosphatidylcholine (DMPC/DSPC) lipid bilayers. The same...
