Muscle contraction
### Muscle contraction

Physiology of [muscle contraction](/wiki/Muscle_contraction "Muscle contraction") involves several interactions. [Myosin](/wiki/Myosin "Myosin") filaments act as [molecular motors](/wiki/Molecular_motor "Molecular motor") and by binding to [actin](/wiki/Actin "Actin") enables filament sliding. Furthermore, members of the [skeletal muscle](/wiki/Skeletal_muscle "Skeletal muscle") [lipid droplet\-associated proteins](/wiki/Lipid_droplet-associated_protein "Lipid droplet-associated protein") family associate with other proteins, as activator of [adipose triglyceride lipase](/wiki/Adipose_triglyceride_lipase "Adipose triglyceride lipase") and its [coactivator](/wiki/Coactivator "Coactivator") comparative gene identification\-58, to regulate [lipolysis](/wiki/Lipolysis "Lipolysis") in skeletal muscle
