Trådliknande proteiner som utgör huvuddelen av muskelfibrernas tunna trådar. Trådarna (också benämnda filamentöst - eller F-aktin) kan sönderdelas i globulära underenheter (G-aktin) bestående av en e nda polypeptid, 375 aminosyror lång. I samverkan med myosin ansvarar aktin för musklernas sammandragning och avslappning.
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.
