Somites, precursors for the segmental structures such as the vertebral column, ribs and skeletal muscles, form periodically by segmentation of the rostral parts of the presomitic mesoderm (PSM). This periodic event is regulated ...

Muscle contraction and many other movement processes are controlled by the interplay between myosin and actin filaments. Two further proteins, tropomyosin and troponin, regulate how myosin binds to actin. While theoretical ...
