Actin

Introduction: Actin

Description of Actin

Actin: globular subunit of microfilaments, whose ATP-dependent polymerization and movement underlies many dynamic cellular phenomena in addition to muscle contraction; actin is one of the most abundant proteins in eukaryotic cells.

Actin: 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.
