The adapter protein CrkII regulates neuronal Wiskott-Aldrich syndrome protein, actin polymerization, and tension development during contractile stimulation of smooth muscle.

Abstract excerpt

Actin polymerization has been shown to occur in tracheal smooth muscle tissues and cells in response to contractile stimulation, and there is evidence that the polymerization of actin is required for contraction. In tracheal smooth muscle, agonist-induced actin polymerization is mediated by activation of neuronal Wiskott-Aldrich syndrome protein (N-WASp) and the Arp (actin-related protein) 2/3 complex, and...
