Cytoskeletal elements
What are the three major subdivisions of cytoskeletal elements?
For each subdivision, know the following:
What are the major monomers called?
for intermediate filaments, name two proteins that function as intermediate filaments, and
indicate where they are found (organelle and cell)?
What is the general name of the structure from which microtubules originate?
Are they polar? If so, what are the two ends called?
Are they dynamic?
Do motor proteins move along them? What is the name of each motor protein?
For each motor protein
On which cytoskeletal element does it move?
In which direction does it move?
Which movement corresponds to anterograde transport? Which movement corresponds to
retrograde transport?
What types of structures are moved along each cytoskeletal element? If nothing is carried, what
structures are supported by the cytoskeletal element?
