WitrynaEach myosin head, also called subfragment-1 (S1), is composed of a motor domain that contains the actin and adenosine triphosphate (ATP)-binding region, and an elongated single α-helix that is stabilized by the binding of the essential light chains (ELC) and regulatory light chains (RLC) (Figure 1(b)).The ELC, which abuts the motor domain, is … WitrynaSignificance. A key feature of plant cells is rapid cytoplasmic streaming that is driven by myosin motors. However, specific mechanisms of myosin-dependent streaming are poorly understood. Here, we characterize a dense network of plant myosins and their receptors and adaptors that, jointly with myosins, appear to mediate cytoplasmic …
