Previous studies have demonstrated that conventional actin preparations contain a potent factor which reduces the low shear viscosity of actin filaments (1). In this paper we demonstrate that Cap Z( 36 32), a recently described protein from skeletal muscle that caps the barbed end of actin filaments and localizes to the Z-line of skeletal muscle (2,3), is the major factor affecting the low shear viscosity of actin prepared from muscle as described by Spudich and Watt (4).
