Aging, Alzheimer’s, and APOE genotype influence the expression and neuronal distribution patterns of microtubule motor protein dynactin-P50

Frontiers in Cellular Neuroscience, 2015
Reports from neural cell cultures and experimental animal studies provide evidence of age- and disease-related changes in retrograde transport of spent or misfolded proteins destined for degradation or recycling. However, few studies address these issues

Dynactin subunit p150(Glued) is a neuron-specific anti-catastrophe factor. [PDF]

PLoS Biology, 2013
Regulation of microtubule dynamics in neurons is critical, as defects in the microtubule-based transport of axonal organelles lead to neurodegenerative disease.

Novel Postzygotic Variants Associated With Hypomelanosis of Ito Expand the ACTB‐Related Neurocutaneous Disease Spectrum

Clinical Genetics, Volume 110, Issue 3, Page 369-373, September 2026.
We describe a previously unreported phenotype related to postzygotic ACTB variants with hypomelanosis of Ito, characterized by hypopigmentation associated or not with neurodevelopmental features, distinct from Becker presentations, bridging constitutional neurodevelopmental and somatic cutaneous phenotypes.

The human cytoplasmic dynein interactome reveals novel activators of motility

eLife, 2017
In human cells, cytoplasmic dynein-1 is essential for long-distance transport of many cargos, including organelles, RNAs, proteins, and viruses, towards microtubule minus ends.

Shared and specific molecular mechanisms of proteasome inhibitors in chemotherapy‐induced peripheral neurotoxicity

British Journal of Pharmacology, Volume 183, Issue 16, Page 5120-5147, August 2026.
This study compares the molecular mechanisms of chemotherapy‐related peripheral neurotoxicity of two proteasome inhibitors, bortezomib and carfilzomib, using a multidisciplinary approach to reveal that, alongside shared effects on mitochondria structure and function, the more neurotoxic drug BTZ has specific effects on microtubules and mitochondrial ...

The Dynactin Complex Enhances the Speed of Microtubule-Dependent Motions of Adenovirus Both Towards and Away from the Nucleus

Viruses, 2011
Unlike transport vesicles or organelles, human adenovirus (HAdV) directly binds to the microtubule minus end-directed motor dynein for transport to the nucleus. The dynein cofactor dynactin enhances nuclear transport of HAdV and boosts infection.

Structural organization of the dynein–dynactin complex bound to microtubules [PDF]

Nature Structural & Molecular Biology, 2015
Cytoplasmic dynein associates with dynactin to drive cargo movement on microtubules, but the structure of the dynein-dynactin complex is unknown. Using electron microscopy, we determined the organization of native bovine dynein, dynactin and the dynein-dynactin-microtubule quaternary complex.

A Bifunctional T3SS‐Effector Simultaneously Cleaves Host MAP Kinase and Inhibits PPM1A Phosphatase

Advanced Science, Volume 13, Issue 37, 3 July 2026.
Pathogenic bacteria exploit the metalloprotease effector NleD to subvert host defenses. Structural, biochemical, and infection analyses reveal a bifunctional mechanism by which NleD binds and inhibits the host phosphatase PPM1A while preserving its proteolytic activity against MAPKs.

Localised dynactin protects growing microtubules to deliver oskar mRNA to the posterior cortex of the Drosophila oocyte

eLife, 2017
The localisation of oskar mRNA to the posterior of the Drosophila oocyte defines where the abdomen and germ cells form in the embryo. Kinesin 1 transports oskar mRNA to the oocyte posterior along a polarised microtubule cytoskeleton that grows from non ...

Dynactin polices two-way organelle traffic [PDF]

The Journal of Cell Biology, 2003
How is the bidirectional motion of organelles controlled? In this issue, Deacon et al. (2003) reveal the unexpected finding that dynactin (previously known to control dynein-based motility) binds to kinesin II and regulates anterograde movement of Xenopus melanosomes.
