Actin

Definition

Actin is a globular protein that forms microfilaments in the cytoskeleton of eukaryotic cells. It plays a crucial role in various cellular processes, including muscle contraction, cell motility, and intracellular transport. Actin filaments, also known as F-actin, are involved in maintaining the shape of cells and in the movement of organelles.

Synonyms

• Microfilament
• Cytoskeletal protein
• Contractile protein

Antonyms

• None (Actin does not have direct antonyms as it is a specific type of protein)
