WebDec 22, 2010 · For example, blocking activity-induced cytoplasmic alkalinization with folimycin or bafilomycin, two selective inhibitors of the proton pump, reduced the endocytic uptake of FM1-43, suggesting that cytosolic alkalinization promotes endocytosis. The authors point out that this effect could be due to the demonstrated pH sensitivity of ... WebAug 4, 2006 · Interestingly, adk1-1 does not affect gravity-induced cytoplasmic alkalinization of the root statocytes, suggesting either that ADK1 functions between cytoplasmic alkalinization and PIN3 relocalization in a linear pathway or that the pH and PIN3-relocalization responses to gravistimulation belong to distinct branches of the …
