Exchange of microtubule molecular motors during melanosome transport in Xenopus laevis melanophores is triggered by collisions with intracellular obstacles
(Humana Press, 2008-12)
The observation that several cargoes move bidirectionally along microtubules in vivo raised the question regarding how molecular motors with opposed polarity coordinate during transport. In this work, we analyzed the switch ...
Melanocytes in the testes of Eupemphix nattereri (Anura, Leiuperidae): Histological, stereological, and ultrastructural aspects
(Wiley-Blackwell, 2007-07-01)
Ectothermic vertebrates have a well-developed system of melanin-containing cells, which localize in several organs and tissues and compose an extracutaneous pigmentary system. This research aimed at characterizing histological ...
Pterosaur melanosomes support signalling functions for early feathers

Upper limits of laser pulse widths required for melanosome and epidermal specific damage
(1988)
A critical analysis of thermal relaxation times used as an upper limit of laser pulse widths after the absorption of laser radiation by pigmented epidermal lesions has been made. Only the case in which the radiation is ...
Organelle transport along microtubules in Xenopus melanophores: Evidence for cooperation between multiple motors
(Elsevier, 2006-12)
Xenopus melanophores have pigment organelles or melanosomes which, in response to hormones, disperse in the cytoplasm or aggregate in the perinuclear region. Melanosomes are transported by microtubule motors, kinesin-2 and ...
Melanosomes transported by myosin-V in xenopus melanophores perform slow 35 nm steps
(Cell Press, 2006-12)
We studied the motion of pigment organelles driven by myosin-V in Xenopus melanophores using a tracking technique with precision of 2 nm. The organelle trajectories showed occasional steps with a distribution centered at ...
