In the present study, we demonstrate that the acidic phospholipid , phosphatidylinositol 4,5-bisphosphate (PIP 2 ), provides an alternative mechanism for the activation of Cdc42Hs. Among a variety of lipids tested, only PIP 2 was able to stimulate GDP release from Cdc42Hs in a dose-...
The MA3-500 antigen is liposomes containing synthetic di-palmitoyl ptdlns(4,5)P2. 靶标信息 Phosphatidylinositol 4,5-bisphosphate or PIP2 is an important second messenger for a number of signaling processes. When certain extracellular signals are received, Phosphilipase C cleav...
Phosphatidylinositol 4,5-bisphosphate (PIP(2)) is a membrane lipid found in all eukaryotic cells, which regulates many important cellular processes, including ion channel activity. In this study, we used inside-out patch clamp technique, immunoprecipitation, and Western blot analysis to investigate th...
Both syt1 and Doc2尾 bind the dynamically regulated plasma membrane lipid phosphatidylinositol 4,5-bisphosphate (PIP 2 ), but it is unclear whether PIP 2 serves only as a membrane contact or enables specialized membrane-binding modes by these Ca 2+ sensors. Furthermore, it has been shown ...

Synaptic-vesicle exocytosis is mediated by the vesicular Ca2+sensor synaptotagmin-1. Synaptotagmin-1 interacts with the SNARE protein syntaxin-1A and acidic phospholipids such as phosphatidylinositol 4,5-bisphosphate (PIP2). However, it is unclear how these interactions contribute to triggering membrane ...
