research Two-ligand priming mechanism for potentiated phosphoinositide synthesis is an evolutionarily conserved feature of Sec14-like phosphatidylinositol and phosphatidylcholine exchange proteins

25 citations , May 2016 in “Molecular biology of the cell”

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.

research Deletion analysis of AGD1 reveals domains crucial for its plasma membrane recruitment and function in root hair polarity

11 citations , June 2017 in “Journal of cell science”

In this study, researchers found that AGD1 is crucial for membrane recruitment during root hair development in Arabidopsis thaliana, with its pleckstrin homology domain essential for targeting specific plasma membrane regions.

research A phosphoinositide-mediated switch of GET pathway receptor dimerization in Arabidopsis

October 2025 in “Proceedings of the National Academy of Sciences”

This study identifies the PI4P-RHD4 module as a key regulator of GET pathway receptor dynamics in Arabidopsis, affecting TA protein insertion and root hair growth.

Retinoid-Mediated Stimulation of Steroid Sulfatase Activity in Myeloid Leukemic Cell Lines Requires RARα and RXR and Involves the Phosphoinositide 3-Kinase and ERK-MAP Kinase Pathways

research Retinoid-mediated stimulation of steroid sulfatase activity in myeloid leukemic cell lines requires RARα and RXR and involves the phosphoinositide 3-kinase and ERK-MAP kinase pathways

24 citations , September 2005 in “Journal of Cellular Biochemistry”

This study found that all-trans and 9-cis retinoic acids increase steroid sulfatase activity in HL60 cells through mechanisms involving RARα/RXR heterodimers and multiple signaling pathways.
