Transport along microtubules

Endosomes move along microtubules

and microtubules (green) in a HeLa cell

Induced  movement of mitochondria and peroxisomes
The N-terminal part of BICD2 interacts with the dynein motor. At the beginning of the movie BICD2 N-terminus is recruited to mitochondria and peroxisomes (green) with the aid of regulated heterodimerisation system (FRB-FKPB system, Ariad). This results in the directional transport of these organelles along microtubules (red) to the microtubule-organising centre.

Dynamics of GFP-Rab6-positive vesicles
GFP-Rab6 decorates the Golgi apparatus and cytoplasmic vesicles, which move
predominantly from the centre of the cell to the periphery.
