Isolation and localization from chicken gizzard of an inhibitory protein for Mg2+-activated skeletal muscle actomyosin ATPase
Abstract
An inhibitory protein for Mg2+-activated actomyosin ATPase from rabbit skeletal muscle was prepared from frozen chicken gizzard and purified by DEAE-Sephadex chromatography and gel filtration. 2. The inhibition by this protein was released by the addition of skeletal muscle troponin C and was independent of gizzard tropomyosin. 3. Localization of the inhibitory protein in gizzard muscle tissue and gizzard thin filaments was demonstrated by immunohistological techniques and immunodiffusion tests.
