ABSTRACT
We have performed an 80 ns molecular dynamics (MD) simulation of human red blood erythrocyte asymmetric membrane model. The NAMD code and CHARMM27 force field were used. We have estimated some features of embedded GpA protein and have discussed some important problems concerning the interaction between the protein and surrounding media. It is stated that the lipid environment and protein immediate neighboring lead to the changes in helix-helix association, as well as to the protein orientation. The interaction nature between protein and neighboring phospholipid chains are dominant forces governing to helix-helix association.

    To identify the ion channels involved in erythrocyte volume regulation, whole-cell currents from human red blood cells (RBCs) were recorded in isotonic, hypotonic and hypertonic media. In isotonic NaCl bath solution, whole-cell currents rectified outwardly with reversal potentials (Vrev) between...

    A definition of the term "erythrocyte" is presented. It refers to a circulating red blood cell, or a mature red blood cell or corpuscle shaped in the form of a nonnucleated, yellowish, biconcave disk. An erythrocyte consists of a respiratory pigment, called hemoglobin, enclosed in a membrane of...
