Abstract
Addition of Ins(1,3,4,5)P4 at micromolar concentrations causes release of Ca2+ from electroporated L1210 cells, but not from digitonin-permeabilized cells. This was shown to be due to its conversion into Ins(1,4,5)P3, because only the electroporated cells convert Ins(1,3,4,5)P4 into Ins(1,4,5)P3. Thus electroporation appears to activate or expose an Ins(1,3,4,5)P4 3-phosphatase.Entities:
