What does ACTIN mean in Scrabble?
noun
technical
A protein that combines with myosin to form the contractile filaments found in muscle cells and in the cytoskeleton of many other cell types.
Actin exists in two forms, a globular monomer and a fibrous polymer, and a cell can rapidly convert between them to reshape itself. Muscle contraction depends on actin filaments sliding past filaments of myosin, shortening the muscle fiber with each contraction. Beyond muscle, actin also forms part of the skeleton that gives ordinary cells their shape and lets them move, divide, or extend projections.
How ACTIN is used
Used mainly in biology and biochemistry writing rather than in everyday conversation.
- The biology textbook explained how actin filaments give a cell its shape.
- Actin and myosin together allow a muscle fiber to shorten.
- Researchers stained the actin in the cell to see its outline under the microscope.
- Without actin, a cell would have no internal scaffolding to hold its form.
- The lab measured how quickly actin assembled into long filaments.
