PI(4,5)P2-binding effector proteins for vesicle exocytosis [PDF]
Biochimica et Biophysica Acta (BBA) - Molecular and Cell Biology of Lipids, 2015 PI(4,5)P₂participates directly in priming and possibly in fusion steps of Ca²⁺-triggered vesicle exocytosis. High concentration nanodomains of PI(4,5)P₂reside on the plasma membrane of neuroendocrine cells. A subset of vesicles that co-localize with PI(4,5)P₂ domains appear to undergo preferential exocytosis in stimulated cells.

Frontiers in Pharmacology, 2015 Transient receptor potential canonical (TRPC) channels are Ca2+-permeable, nonselective cation channels that carry receptor-operated Ca2+ currents (ROCs) triggered by receptor-induced, phospholipase C (PLC)-catalyzed hydrolysis of phosphatidylinositol 4 ...

Septin‐based readout of PI(4,5)P2 incorporation into membranes of giant unilamellar vesicles [PDF]
, 2018 International audienceSeptins constitute a novel class of cytoskeletal proteins. Budding yeast septins self-assemble into non-polar filaments bound to the inner plasma membrane through specific interactions with L-α-phosphatidylinositol-4,5-bisphosphate (

Biology, 2021 TREK-2-like channels in the pyramidal neurons of rat prefrontal cortex are characterized by a wide range of spontaneous activity—from very low to very high—independent of the membrane potential and the stimuli that are known to activate TREK-2 channels ...

Anionic lipids activate group IVA cytosolic phospholipase A2 via distinct and separate mechanisms
Journal of Lipid Research, 2007 Previously, ceramide-1-phosphate (C1P) and phosphatidylinositol-4,5-bisphosphate [PI(4,5)P2] were demonstrated to be potent and specific activators of group IVA cytosolic phospholipase A2 (cPLA2α). In this study, we hypothesized that these anionic lipids

TRPV4 channel activity is modulated by direct interaction of the ankyrin domain to PI(4,5)P2 [PDF]
, 2014 Mutations in the ankyrin repeat domain (ARD) of ?TRPV4 are responsible for several channelopathies, including Charcot?Marie?Tooth disease type 2C and congenital distal and scapuloperoneal spinal muscular atrophy.

Modulation of KV7 Channel Deactivation by PI(4,5)P2 [PDF]
Frontiers in Pharmacology, 2020 The activity of KV7 channels critically contributes to the regulation of cellular electrical excitability in many cell types. In the central nervous system, the heteromeric KV7.2/KV7.3 channel is thought to be the chief molecular entity giving rise to M-currents.

Bem1p contributes to secretory pathway polarization through a direct interaction with Exo70p. [PDF]
, 2014 The exocyst serves to tether secretory vesicles to cortical sites specified by polarity determinants, in preparation for fusion with the plasma membrane.

FEBS Letters, EarlyView.Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Competitive Interactions of PIRT and PI(4,5)P2 Modulate TRPM8 [PDF]
Biophysical Journal, 2017 PIRT or Phosphoinositide regulator of TRP is a small membrane protein that has been shown to modulate the function of TRP channels. PIRT is implicated in fine-tuning the physiological roles that TRP channels play in thermosensing and ligand activation; suggesting roles for PIRT:TRP complexes in pathophysiologies such as pruritus and chronic pain.
