General Information

EC Number General Information Comment Organism
3.1.3.36 malfunction inactivation of GH1 results in massive accumulation of both phosphatidylinositol 4-phosphate and phosphatidylinositol 4,5-bisphosphate, while excessive GH1 causes their depletion. Superabundant phosphatidylinositol 4-phosphate and phosphatidylinositol 4,5-bisphosphate could both disrupt actin cytoskeleton organization and suppress cell elongation. Overaccumulation of phosphatidylinositol 4,5-bisphosphate resulting from dysfunction of SAC phosphatase possibly perturbs Arp2/3 complex-mediated actin polymerization, thereby disordering cell development Oryza sativa Japonica Group
