A key B-cell tyrosine kinase that adopts an autoinhibited conformation, and can be activated by either membrane recruitment or soluble inositol hexakisphosphates in solution.
Unique biosensor design and protein-engineering enables direct visualization of the active form of Fyn kinase with high specificity, minimal perturbation and shows cellular signaling to be compartmentalized and pulsatile.

The α1-adrenergic receptor augments the activity of the L-type Ca2+ channel CaV1.2 through PKC and the tyrosine kinases Pyk2 and Src and thereby synaptic plasticity.

Extracellular actin is an evolutionarily-conserved signal of tissue injury that is recognised in the fruit fly via similar machinery as reported in vertebrates.

Epithelial cells coordinate integrin signaling with protrusion via a two-protein module, with one protein defining localization and downstream signaling, the other serving as a phosphorylation switch and providing negative feedback.
A high-throughput technique to characterize the substrate specificities of tyrosine kinases identifies the key features of kinases and substrates that enforce accurate signaling from T cell receptors.

Vascular leakage from pathological vessels in retinopathy aggravates the disease, but endothelial junction stability and barrier integrity can be restored by blocking formation of nitric oxide.
