The G protein subunits Gβγ and the signaling lipid PIP2 are simultaneously needed to activate the potassium ion channel GIRK2 to control the voltage across a lipid bilayer, while sodium ions modulate these molecules' effects.
Multiple independent analyses reveal that a specific membrane lipid directly interacts with the signalling protein Wingless to promote synapse growth at the Drosophila neuromuscular junctions.
Clustering the B cell receptor generates a membrane domain analogous to the liquid-ordered phase, localizing proteins involved in early receptor activation.
Constitutive sphingosine 1-phosphate signaling via the G-protein coupled receptor S1PR3 in mechanonociceptive somatosensory neurons is required for normal behavioral responses to noxious mechanical stimuli.
The biogenesis of lipid droplets induced by Wnt3a is controlled by the transcription factor TFAP2, which presumably acts as a 'master' regulator of lipid droplet biogenesis.
Germ cell ablation delays C. elegans aging, in part, because unconsumed fat triggers activation of the detoxification factor SKN-1/Nrf, which is regulated by lipid signals and maintains lipid homeostasis.
Yeast specific lipids promote the transport of lipid transfer protein (LTP) across the blood brain barrier to the neurons that regulate systemic insulin signaling.
