The ubiquitin ligase c-Cbl preferentially targets unique-region phosphorylated LynA for rapid degradation, regulating its expression and differentially tuning signaling responsiveness in macrophages and mast cells.
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 primary molecular mechanosensor involved in a physiological process of mechanically induced cell fate differentiation is revealed here for the first time in vivo, highly sensitive and potentially shared by all metazoan epithelia.
Extensive cytological and biochemical analyses show that the conserved Sf3A2 and Prp31 splicing factors bind microtubules and the Ndc80 complex, playing direct mitotic functions in both Drosophila and human mitosis.
Pathological vessel leakage in mouse retinopathy models depends on VE-cadherin Y685 phosphorylation status, which in turn is regulated by a signaling cascade originating with VEGFR2 Y949 phosphorylation.
