actin lietuviškai

Paaiškinimas anglų kalba

• one of the proteins into which actomyosin can be split; can exist in either a globular or a fibrous form
• Filamentous proteins that are the main constituent of the thin filaments of muscle fibers. The filaments (known also as filamentous or F-actin) can be dissociated into their globular subunits; each subunit is composed of a single polypeptide 375 amino acids long. This is known as globular or G-actin. In conjunction with MYOSINS, actin is responsible for the contraction and relaxation of muscle.
