Effects of anion transport inhibitors on hemolysis of human erythrocytes under hydrostatic pressure.

abstract：:During a large-scale in vitro translation analysis of a human full-length cDNA bank, we found many clones producing in vitro translation products showing ladder bands on a fluorogram with the equidistance of about 9 kDa at the position larger than the molecular mass expected from the open reading frame. We have analyz...

By monitoring fluorescent intensity of pyrenyl-actin, it was found that aplyronine A inhibited both the velocity and the degree of actin polymerization. Aplyronine A also quickly depolymerized F-actin. The kinetics of depolymerization suggest that aplyronine A...
