Cell Motility

2. a protein complex that serves as a nucleating site for actin at the leading edge of motion
3. the process by which a cell directs actin polymerization at the leading edge, forms focal adhesions, contracts myosin at the rear while releasing rear connections, and moves forward
4. when axon growth cones follow a gradient of diffusable factors
7. factors that are produced and act within a single cell
8. a form of sexual reproduction in yeast where two oppositely oriented yeast cells follow mating factor and protrude towards each other
9. an experiment where a factor is removed from a group of cells; if the cells without the factor do not respond normally, it is autonomous; if they do respond normally, it is non-autonomous
10. are necessary for a cell to initiate a certain action prior to a signal being given
12. cells follow a gradient of diffusable factors
15. cells follow an applied voltage
16. a g-protein that regulates the actin polymerization pathway at the leading edge

1. factors that are produced from surrounding cells and act as cues to guide a cell
5. guide cells to perform a specific action
6. a form of asymmetric cell division in yeast initiated by localizing ash1 mRNA to a specific part of the cell
11. cells follow a gradient of stiffness
13. the main protein type that is associated with focal adhesions
14. cells follow a gradient of immobilized molecules
16. a g-protein that regulates stress fiber formation, myosin contractility, and focal adhesion formation
