A role for the Ca(2+)-dependent tyrosine kinase Pyk2 in tonic depolarization-induced vascular smooth muscle contraction
{{output}}
Depolarization of the plasma membrane is a key mechanism of activation of contraction of vascular smooth muscle. This is commonly achieved in isolated, de-endothelialized vascular smooth muscle strips by increasing extracellular [K(+)] (replacing Na(+) by K(+)... ...
