Phosphatidylinositol 4,5-bisphosphate (PI(4,5)P2 or PIP2) regulates the activities of numerous membrane proteins, including diacylglycerol(DAG)-activated TRPC3/6/7 channels.

Voltage-Sensitive PIP2 Phosphatase Shows PIP2 Requirements for KCNQ and Ca2+ Channels [PDF]
The four talks in this symposium highlight the dependence of ion channel function on membrane phospholipids and fatty acids. Although of low abundance (1-2%), the phosphoinositide phosphatidylinositol 4,5-bisphosphate (PIP2) is a signature lipid of plasma membranes.

CO2 Transport by PIP2 Aquaporins of Barley [PDF]
CO2 permeability of plasma membrane intrinsic protein 2 (PIP2) aquaporins of Hordeum vulgare L. was investigated. Five PIP2 members were heterologously expressed in Xenopus laevis oocytes. CO2 permeability was determined by decrease of cytosolic pH in CO2-enriched buffer using a hydrogen ion-selective microelectrode.

Striking a balance: PIP2 and PIP3 signaling in neuronal health and disease
Phosphoinositides are membrane phospholipids involved in a variety of cellular processes like growth, development, metabolism, and transport. This review focuses on the maintenance of cellular homeostasis of phosphatidylinositol 4,5-bisphosphate (PIP2 ...

PIP2 PIP2 Hooray for Maxi K+ [PDF]
Voltage-gated K+ (KV) channels contain a voltage-sensing transmembrane segment that moves in response to changes in membrane potential. A small “gating” current arises from the translocation of positively charged residues within the channel's voltage sensor.

Synthetic Manipulation of PIP2 Levels and PIP2-Associated Chemotactic Signaling Dissection in Dictyostelium [PDF]
Phosphatidylinositol 4,5-bisphosphate (PIP2) has been shown involved in key chemotactic signaling pathways in Dictyostelium, but our understanding of its roles in this signaling network is very limited. To explore the hypothesis that PIP2 negatively regulate chemotactic signaling events, we used the Chemically-induced Dimerization system, which allows ...

The biphasic increase of PIP2 in the fertilized eggs of starfish: new roles in actin polymerization and Ca2+ signaling. [PDF]
BACKGROUND: Fertilization of echinoderm eggs is accompanied by dynamic changes of the actin cytoskeleton and by a drastic increase of cytosolic Ca(2+). Since the plasma membrane-enriched phospholipid phosphatidylinositol 4,5-bisphosphate (PIP2) serves as

GIRK channels control spike frequency in atrial pacemaker cells and inhibitory potentials in neurons. By directly responding to G proteins, PIP2 and Na+, GIRK is under the control of multiple signaling pathways. In this study, the mammalian GIRK2 channel
