Site-directed spin labeling and electron paramagnetic resonance spectroscopy have recently experienced an outburst of multiple applications in protein science. Numerous interesting strategies have been introduced for determining the structure of proteins and its conformational changes at the level of the backbone fold. Moreover, considerable technical development in the field makes the technique an...
The object of this paper is to review briefly the studies on the interaction of red blood cell membrane skeletal proteins and their non-erythroid analogues with lipids in model systems as well as in natural membranes. An important question to be addressed is the physiological significance and possible regulatory molecular mechanisms in which these interactions are engaged.
Polyethylene glycol (PEG) induces fusion of cells creating fused cell pairs and larger cell aggregates. However the precise mechanism of its action on cell membranes remains unclear. In the present study we attempted to determine how PEG interacts with the membrane of red blood cell. It is known that PEG, at concentrations that induce cell fusion, causes strong swelling of erythrocytes which appeared...
