In Drosophila oocytes, the exclusion of the scaffold protein PAR3 from the posterior cortex depends on PAR1 and endocytosis, while its anterior localisation requires microtubules and recycling endosomes.
TRPV4 channels in brain capillaries are suppressed by the phosphoinositide PIP2 and activated by receptor agonists implicated in neurovascular coupling.
Epidermal cells in vertebrates and invertebrates ensheath portions of somatosensory neurons via a conserved morphogenetic mechanism, and this ensheathment regulates morphogenesis and function of Drosophila nociceptive neurons.
Genetic and biochemical analysis of two enzymes reveals that inositol pyrophosphate signaling molecules allow plants to sense and regulate cellular phosphate levels, and to take up more phosphate when needed.
Synergistic interactions with PI(4,5)P2 and activated Rho1, which are enriched at the apical membrane of tubular organs, facilitate tight apical targeting of the formin Diaphanous.
The interplay between the Flower Ca2+ channel and PI(4,5)P2 spatiotemporally couples synaptic vesicle exocytosis to activity-dependent bulk endocytosis and synaptic vesicle reformation from bulk endosomes.
A set of sexually dimorphic neurons in female flies is part of a recurrent neural network and drives minutes-long persistent neural activity and persistent social behaviors.
Calcium influx stimulates formation of ER/plasma membrane contacts adjacent to focal adhesions, and lipid transfer at these sites is required for adhesion disassembly during cell migration.
