If the activity of thymosin β4 was inhibited in fibroblasts, the overall effect would be:

#Unit 2. Cellular Organization

  1. a decrease in cell locomotion because less actin would be recruited to the leading edge.

  2. an increase in cell locomotion because there would be a higher concentration of actin available.

  3. no change in cell locomotion because thymosin β4 doesn’t interact with Rho, Rac, or Cdc42.

  4. decrease in cell locomotion because there would be a higher concentration of actin available.
