An actin-like protein isolated from human red-cell membranes undergoes G-F transformation, forms filaments, and closely resembles muscle actin.
The study confirms the existence of an actin-like protein in human red-cell membranes that closely resembles muscle actin in its biochemical and structural properties.
The existence of an actin-like protein in human red-cell membranes has been confirmed. The protein was extracted from acetone-treated ghosts and purified by (NH4)2SO4 fractionation. The protein undergoes G-F transformation and forms filaments in the presence of 0.1 M KCl. The filaments can be "decorated" by muscle heavy meromyosin. The protein has the same molecular weight as muscle actin and interacts with muscle myosin. All these properties show that the protein closely resembles muscle actin.
Tsuyoshi Ohnishi (Tue,) reported a other. Isolation of actin-like protein was evaluated on Characterization of actin-like protein properties. An actin-like protein isolated from human red-cell membranes undergoes G-F transformation, forms filaments, and closely resembles muscle actin.
