title: Actin motility: staying on track takes a little more effort.
abstract: The pigment cells of amphibians and fish have provided excellent models for understanding how actin and microtubule motors move organelles along the complex trailway of filaments in the cytoplasm. Recent work provides more evidence that these motors are engaged in a continuous tug-of-war.
