Biological Activity for Dooku 1
Dooku 1 reversibly blocks Yoda1 (Cat. No. 5586) activity (IC50 = ~1.5 μM). Exhibits no effect on constitutive Piezo1 channel activity, but antagonizes Yoda1-induced Piezo1 activation in endothelial cells, and inhibits Yoda1-induced Ca2+-entry in vitro. Also blocks Yoda1-induced relaxation of aorta ex vivo.

Peripheral sensitization is the reduction in the threshold of excitability of sensory neurons that results in an augmented response to a given external stimulus. This poster outlines the excitatory and inhibitory signaling pathways involved in modulation of peripheral sensitization. The role of ion channels, GPCRs, neurotrophins, and cytokines in sensory neurons are also described.
