Actin is a globular multi-functional protein that forms microfilaments. Actin takes part in many important cellular processes, including: muscle contraction; cell motility; cell division and cytokinesis; vesicle and organelle movement; cell signaling; and the establishment and maintenance of cell junctions and cell shape.

What is rigor and its function?
Rigor has no function it is a reaction to the exhaustion of oxygen supply to the dying tissue. The release of myosin-actin requires ATP derived from oxidative metabolism the end result is a rigidity.
What is the thin filament of the myocardial cell?
Actin
What are Analogies for microfillament?
Assuming you meant microfilament, it is mostly comprised of linear polymers of actin, or actin filaments. Some use "actin filament" (or sometimes just "actin") and "microfilament" interchangably.
What are the two contractile proteins of muscle?
The two types of protein that are in your muscle cells are actin and myosin. What they do is they slide past each other and that makes a muscle cell work.
The drug cytochalasin B blocks the function of actin which of the following aspects of the cell cycle would be most disrupted by cytochalasin B?
Cleavage furrow formation
What is the function of titin and nebulin?
Their function is to hold both Actin and Myosin in their exact position or to stabilized the actin and myosin
What is the function of tropomyosin?
The function of tropomyosin is to cover the active site on the G Actin or Actin, so nothing can stick to it, when muscle is at rest.
What is function of tropomyosin on a relaxed actin molecule?
Need help finding the answer
What is the role of the protein actin?
Actin is found in muscle tissue ( along with myosin) and makes up microfilaments which are responsible for cellular movement and also function in cell division.
The thin filaments contain a polypeptide subunit G actin that seems to have no function?
FALSE
What is an actinin?
An actinin is a microfilament protein which has a function in the attachment of actin fibres in muscle cells.
What would happen if actin were damaged or not present?
We would die. Just die. Cause muscles wouldn't function without actin. I think. So yeah. Spoken as a high school biology student
What is the function of actin filaments?
providing structure support and involved in movement.
What is the function of myosin?
Myosin is responsible for actin-based muscular mobility/contraction.
What are the proteins are involved in muscle contraction?
Actin and myosin
What are the names of protein filaments in a muscle fiber?
Actin Filaments
What are actin fibers?
Actin is a contractile protein fibers present in muscles.It occurs in two forms a.monomeric G actin b. polymeric F ACTIN.
