Cargo adaptors regulate stepping and force generation of mammalian dynein-dynactin. [PDF]
Cytoplasmic dynein is an ATP-driven motor that transports intracellular cargos along microtubules. Dynein adopts an inactive conformation when not attached to a cargo, and motility is activated when dynein assembles with dynactin and a cargo adaptor.

Targeted expression of truncated glued disrupts giant fiber synapse formation in Drosophila [PDF]
Glued1 (Gl1) mutants produce a truncated protein that acts as a poison subunit and disables the cytoplasmic retrograde motor dynein. Heterozygous mutants have axonal defects in the adult eye and the nervous system.

RUFY3 links Arl8b and JIP4-Dynein complex to regulate lysosome size and positioning
Lysosomes move along microtubule tracks, and Arl8b is known to stimulate their anterograde transport. Here, the authors identified RUFY3 as an Arl8b effector that interacts with dynein-dynactin to drive retrograde transport and perinuclear lysosome ...

Hook3 is a scaffold for the opposite-polarity microtubule-based motors cytoplasmic dynein-1 and KIF1C. [PDF]
The unidirectional and opposite-polarity microtubule-based motors, dynein and kinesin, drive long-distance intracellular cargo transport. Cellular observations suggest that opposite-polarity motors may be coupled.

Homolog pairing during meiosis : dyneins on the move [PDF]
Meiosis is a specialized form of cell division that generates haploid gametes from diploid cells. This is achieved by having 1 round of DNA replication followed by 2 rounds of nuclear division.

Recruitment of two dyneins to an mRNA-dependent Bicaudal D transport complex
We investigated the role of full-length Drosophila Bicaudal D (BicD) binding partners in dynein-dynactin activation for mRNA transport on microtubules. Full-length BicD robustly activated dynein-dynactin motility only when both the mRNA binding protein ...

RUFY3 and RUFY4 are ARL8 effectors that promote coupling of endolysosomes to dynein-dynactin
Organellar transport is carefully regulated, and endolysosome localized ARL8 is important for kinesin recruitment and anterograde movement. Here, the authors show that RUFY3 and RUFY4 promote retrograde transport of endolysosomes by mediating interaction

Emerging Trends of Nanotechnology towards Picotechnology: Energy and Biomolecules [PDF]
In nature, metal oxide particles display their existence at the level of picomolecules in solution state and bioactive states in the body. We present evidence of picomolar behavior of molecules different than nanomolar behavior of particles.

Dynactin Is Required for Microtubule Anchoring at Centrosomes [PDF]
The multiprotein complex, dynactin, is an integral part of the cytoplasmic dynein motor and is required for dynein-based motility in vitro and in vivo. In living cells, perturbation of the dynein–dynactin interaction profoundly blocks mitotic spindle assembly, and inhibition or depletion of dynein or dynactin from meiotic or mitotic cell extracts ...

The mechanisms of microtubule-based mitochondrial transport remain poorly understood. Here, the authors show that the mitochondrial TRAK adaptors activate the dynein-dynactin complex, enhance the motility of kinesin, and can scaffold both motors to ...
