... of cytoplasmic composition of anionic li- pids in membrane binding of K-Ras was evaluated by studying the effect of ATP depletion, which inhibits inward movement of PS, with consequent loss of plasma ... the role of electrical properties of the plasma membrane in the subcellular distribution of K-Ras. In particular, we investigated (a) the role of surface charge on inner...

... localization of cystatin F, its restricted and readily regulated expres- sion [18], selective and not too potent inhibition of cathepsins are all in favor of the active role of cystatin F in processes of ... dilution, cystatin F was equilibrated with a twofold molar excess of papain. The residual activity of papain was measured with Z-FR-AMC. Rel- ative activity of cystatin F...
