Studies on PIP2-bisphosphomonoesterase activity in human platelets.
Blood & Vessel, 1988 An occurrence of phosphatidylinositol 4,5-bisphosphate (PIP2) phosphomonoesterase in human platelets was demonstrated by analyzing phosphoinositides metabolism. The activity of the enzyme was maximum at pH 7.0. It was active even in the absence of Ca2+ or Mg2+ but it was enhanced in the presence of Mg2+ or NaF.

TMEM16A channel signalling microdomains in the regulation of vascular function
The Journal of Physiology, EarlyView.Abstract figure legend Schematic representation of TMEM16A channel signalling microdomains. Calcium influx or calcium release from the endoplasmic/sarcoplasmic reticulum (ER/SR) activates TMEM16A channels through interactions with regulatory proteins in vascular smooth muscle cells or endothelial cells. TMEM16A channel activation drives chloride efflux,

Phosphatidylinositol-4,5-bisphosphate enhances anionic lipid demixing by the C2 domain of PKCα.
PLoS ONE, 2014 The C2 domain of PKCα (C2α) induces fluorescence self-quenching of NBD-PS in the presence of Ca2+, which is interpreted as the demixing of phosphatidylserine from a mixture of this phospholipid with phosphatidylcholine.

Calcium‐activated chloride channels in pericytes and their role in regulating organ blood flow
The Journal of Physiology, EarlyView.Abstract figure legend Pericytes are microvascular mural cells with diverse roles. Contractile pericytes directly regulate local perfusion, while non‐contractile pericytes coordinate upstream vascular contractility via propagating electrical signals.

The Journal of Physiology, EarlyView.Abstract figure legend The capillary–mitochondria–ion channel (CMIC) axis scales structural resources to match functional workload. (Left) In settings of restricted energetic capacity (e.g. cortical neurons), sparse capillary networks and modest mitochondrial pools set a lower energetic ceiling, sufficient to support phasic, low‐workload excitability. (

The Journal of Physiology, EarlyView.Abstract figure legend Schematic outlining the activation of hypoxia‐sensitive pathways, the influence of hypoxia and associated pathways on the cytoskeleton, and the impact of these on disease progression. Abstract A highly‐regulated and dynamic cytoskeleton is vital for functional cellular physiology and the maintenance of homeostasis.

Regulation of WASP: PIP2 Pipped by Toca-1?
Cell, 2004 Cdc42 is a key regulator of cell polarity and actin dynamics. One of its effectors, WASP, initiates the assembly of new actin filaments. In this issue of Cell, show that a previously unknown regulator named Toca-1 is required for Cdc42 to activate WASP.

PLOS ONE, 2015 Translocation to the nucleus of diacylglycerol kinase (DGK)- ζ is dependent on a sequence homologous to the effector domain of Myristoylated Alanine Rich C-Kinase Substrate (MARCKS). These data would suggest that MARCKS could also localize to the nucleus.

The Journal of Physiology, EarlyView.Abstract figure legend Calmodulin (CaM) is a ubiquitous calcium (Ca2+) sensor that translates intracellular Ca2+ signals into modulation of hundreds of effector proteins including ion channels. CaM is increasingly recognized as a key regulator of the transient receptor potential (TRP) channel family, yet the underlying ‘calmodulation playbook’ is only ...
