1 Depletion of PI4KIIIalpha results in impaired electrical responses to light, and reduced plasma membrane levels of PI4P and PI(4,5)P2 Depletion of the conserved proteins Efr3 and TTC7 [also known as StmA and L(2)k14710, respectively, in flies], which assemble PI4KIIIalpha at the plasma membrane, also results in an impaired light response and reduced plasma membrane PI4P and PI(4,5)P2 levels. pi(4,5)p2 Phosphatidylinositol 4-kinase III alpha Drosophila melanogaster
2 Depletion of PI4KIIIalpha results in impaired electrical responses to light, and reduced plasma membrane levels of PI4P and PI(4,5)P2 Depletion of the conserved proteins Efr3 and TTC7 [also known as StmA and L(2)k14710, respectively, in flies], which assemble PI4KIIIalpha at the plasma membrane, also results in an impaired light response and reduced plasma membrane PI4P and PI(4,5)P2 levels. pi(4,5)p2 Phosphatidylinositol 4-kinase III alpha Drosophila melanogaster
3 Thus, PI4KIIIalpha activity at the plasma membrane generates PI4P and supports PI(4,5)P2 levels during receptor activated PLC signaling. pi(4,5)p2 Phosphatidylinositol 4-kinase III alpha Drosophila melanogaster
