I wish to raise the following three questions about Drosophila melanogaster Star:

1. Is Star itself a motor protein?

2. If not, what transports Star from ER to Golgi?

3. Can we observe the intracellular trafficking of Star using AFM in solution?

Addendum primum:

If Star itself is a motor protein, is it monomeric or dimeric?

Addendum secundum:

Interaction between dynein and Star has been reported
