Cardiac and skeletal striated muscles are intricately designed machines
responsible for muscle contraction. Coordination of the basic contractile unit,
the sarcomere, and the complex cytoskeletal networks are critical for contractile
activity. The sarcomere is comprised of precisely organized individual filament
systems that include thin (actin), thick (myosin), titin, and nebulin. Connecting
the sarcomere to other organelles (e.g., mitochondria and nucleus) and serving as
the scaffold to maintain cellular integrity are the intermediate filaments. The
costamere, on the other hand, tethers the sarcomere to the cell membrane. Unique
structures like the intercalated disc in cardiac muscle and the myotendinous
junction in skeletal muscle help synchronize and transmit force. Intense
investigation has been done on many of the proteins that make up these
cytoskeletal assemblies. Yet the details of their function and how they
interconnect have just started to be elucidated. A vast number of human
myopathies are contributed to mutations in muscle proteins; thus understanding
their basic function provides a mechanistic understanding of muscle disorders. In
this review, we highlight the components of striated muscle with respect to their
interactions, signaling pathways, functions, and connections to disease. © 2017
