modulating endothelial monolayer permeability. Posttranslational modifications of RhoA and
Rac1 regulate enzyme activity and subcellular localization, resulting in altered cellular
function. The role of RhoA and Rac1 carboxyl methylation in modulating endothelial
monolayer permeability is not known. In this study, we found that inhibition of
isoprenylcysteine-O-carboxyl methyltransferase (ICMT) with adenosine plus homocysteine …
