Asymmetries in kinesin-2 and cytoplasmic dynein contributions to melanosome transport

The mechanisms involved in bidirectional transport along microtubules remain largely unknown. We explored the collective action of kinesin-2 and dynein motors during transport of melanosomes in Xenopus laevis melanophores. These motors are attached to organelles through accessory proteins establishi...
