Sticholysins (Sts) I and II (StI/II) are pore-forming toxins (PFTs) produced by the Caribbean Sea anemone Stichodactyla helianthus belonging to the actinoporin family, a unique class of eukaryotic PFTs exclusively found in sea anemones. The role of l

Interaction between membrane lipids creates lateral domains within which essential membrane processes like trans-membrane signaling, differentiation etc. take place. Attention has focused on liquid-ordered phases formed by sphingomyelin and cholester

Cholera and the related AB5-subunit toxins co-opt plasma membrane (PM) glycolipids to move retrograde into the endoplasmic reticulum (ER) of the host cell where a portion of the toxin is retro-translocated to the cytosol to induce disease. Only glyco

Several studies suggest that the plasma membrane is composed of micro-domains of saturated lipids that segregate together to form lipid rafts. Lipid rafts have been operationally defined as cholesterol- and sphingolipid-enriched membrane micro-domain

There has been ample debate on whether cell membranes can present macroscopic lipid domains as predicted by three-component phase diagrams obtained by fluorescence microscopy. Several groups have argued that membrane proteins and interactions with th

To understand the role of sphingomyelinase (SMase) in the function of biological membranes, we have investigated the effect of conversion of sphingomyelin (SM) to ceramide (Cer) on the assembly of domains in giant unilamellar vesicles (GUVs). The GUV

To investigate an interfacial behavior of the aglycon of glycyrrhizin (GC), glycyrrhetinic acid (GA), with a lipid raft model consisting of equimolar ternary mixtures of N-palmitoyl sphingomyelin (PSM), dioleoylphosphatidylcholine (DOPC), and cholest

Plasma membrane lipids significantly affect assembly and activity of many signaling networks. The present work is aimed at analyzing, by molecular dynamics simulations, the structure and dynamics of the CD3 ζζ dimer in palmitoyl-oleoyl-phosphatidyl
