The elastic response of active biopolymer networks is determined not only by molecular motors but also by the density and stiffness of crosslinking proteins say US Scientists.
Peng Chen and Vivek B. Shenoy from Brown University, USA, studied the elastic response of actin networks with both compliant and rigid crosslinks by modeling molecular motors as force dipoles.
