Melittin (ML) is a small peptide of 26 residues rich in arginine (Arg) and lysine (Lys). Several studies have been done to understand the mechanism of interaction with neutral and negatively charged lipids. However, it is ...

We demonstrated previously that acetylated tubulin inhibits plasma membrane Ca 2 +-ATPase (PMCA) activity in plasma membrane vesicles (PMVs) of rat brain through a reversible interaction. Dissociation of the PMCA/tubulin ...

Neurotransmitter receptors, the macromolecules specialized in decoding the chemical signals encrypted in the chemical signaling mechanism in the nervous system, occur either at the somatic cell surface of chemically excitable ...

The lipid composition of biological membranes is key for cell viability. Nevertheless, and despite their central role in cell function, our understanding of membrane physiology continues to lag behind most other aspects ...

Background: When purified phagosomes are incubated in the presence of actin under appropriate conditions, microfilaments start growing from the membrane in a process that is affected by ATP and the lipid composition of the ...

UPAR is a GPI anchored protein, which is found in both lipid rafts and in more fluid regions of the plasma membrane. We have studied the role of the ligand uPA on uPAR localization and on the composition of the lipid ...

To identify the changes in the lipid profile of the tear film in two human populations exposed to different levels of particulate material, and its relationship with dry eye, by gas chromatography with mass spectrometry ...

Since the fatty acid ester profile of a given biofuel is relatively consistent with the source's fatty acid profile, the properties of the biodiesel produced from a particular feedstock exhibit predictable quality. Thus, ...
