The idea that aquaporins may only allow permeation of neutral solutes has been challenged. Members of the group led by Caitlin Byrt, Manchun Zhao and Steve Tyerman have reveal that AtPIP2;1 is permeable to both water and Na+ in heterologous systems. The AtPIP2;1 ionic conductance is inhibited by low pH and Ca2+ similar to previous observations for […] Read More...
