research Two-ligand priming mechanism for potentiated phosphoinositide synthesis is an evolutionarily conserved feature of Sec14-like phosphatidylinositol and phosphatidylcholine exchange proteins
This study found that the AtSfh1 protein in Arabidopsis is essential for phosphatidylinositol-4,5-bisphosphate signaling crucial to polarized root hair growth, utilizing both phosphatidylinositol and phosphatidylcholine-binding activities.
