The extend of the contributions of the cytoskeleton to the wound healing program of somatic cells have comparatively received little attention. This review offers a survey of the current knowledge on how actin dynamics, myosin-based contraction and other cytoskeletal structures affects PM and cortical ...
What two things does it bind to? Sarcomere The sarcomere is the contractile unit of the cell and contains the contractile filaments actin and myosin. Sarcomeres line the entire length of each muscle myofibril, allowing muscle contraction to occur in each region o...
We have previously shown that myosin does not have to detach from actin during each cycle of ATP hydrolysis. In the present study, using the A-1 isoenzyme of myosin subfragment 1, we have investigated the nature of the rate-limiting step... LA Stein,PB Chock,E Eisenberg - 《Biochemistry...
As Lin28A has been shown to be associated with brain tumors and neural progenitor proliferation [33,46,75], we next aimed to analyze the influence of Lin28A overexpression on cell proliferation within the cerebral cortex. Quantification of pHH3-positive cells (indicating mitotic cells) showed incr...
is broken down into ADP and phosphate. This gives the myosin energy to “stand up” and bind (or grab on) to actin. This binding between the actin and myosin is called a cross-bridge (like bridging two molecules). Once bound, myosin pulls the actin, shortening the muscl...
Caldesmon inhibits the productive binding of myosin to actin but may allow an interaction of myosin with actin which does not result in ATP hydrolysis: M.E. Hemric and J.M. Chalovich; East Carolina Univ. Med. Sch. Greenville, NC 27858...
All class III myosins have IQ motifs (calmodulin binding sites) in the neck domain; in Myo3A they are also present within the tail domain. There are two unique conserved domains in myosin III tails; one of these has been shown to bind actin and play a role in localization to actin ...

Myosin II does it all: assembly, remodeling, and disassembly of actin networks are governed by myosin II activity. Soft Matter. 9: 7127- 7137.Ideses Y, Sonn-Segev A, Roichman Y, Bernheim-Groswasser A (2013). Myosin II does it all: assembly, remodeling, and disassembly of actin ...
Temperature change does not affect force between regulated actin filaments and heavy meromyosin in single-molecule experiments. J Physiol 574, 877-887.Kawai M, Kido T, Vogel M, Fink RHA, Ishiwata S. Temperature change does not affect force between regulated actin filaments and heavy meromyosin ...
