The Long Haul: Microtubule Motors as the Essential Supply Line for Neuronal Longevity. [PDF]

open access: yesJ Neurochem
To survive a lifetime, neurons depend on a high‐fidelity logistics network powered by microtubule motors. We explore how a broad spectrum of genetic defects in this machinery drive a devastating spectrum of neurodevelopmental and neurodegenerative diseases, including Hereditary Spastic Paraplegia (HSP), Charcot–Marie‐Tooth Type 2 (CMT2), and ...

Conserved roles for the dynein intermediate chain and Ndel1 in assembly and activation of dynein

open access: yesNature Communications, 2023
Processive transport by the microtubule motor cytoplasmic dynein requires the regulated assembly of a dynein-dynactin-adapter complex. Interactions between dynein and dynactin were initially ascribed to the dynein intermediate chain N-terminus and the ...

Dynein/Dynactin-mediated transport of kinetochore components off kinetochores and onto spindle poles induced by nordihydroguaiaretic acid. [PDF]

open access: yesPLoS ONE, 2011
The mitotic checkpoint functions to ensure accurate chromosome segregation by regulating the progression from metaphase to anaphase. Once the checkpoint has been satisfied, it is inactivated in order to allow the cell to proceed into anaphase and ...

dnc-1/dynactin 1 knockdown disrupts transport of autophagosomes and induces motor neuron degeneration. [PDF]

open access: yesPLoS ONE, 2013
Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease characterized by the progressive loss of motor neurons. We previously showed that the expression of dynactin 1, an axon motor protein regulating retrograde transport, is markedly ...

Cytoplasmic dynein-1 cargo diversity is mediated by the combinatorial assembly of FTS–Hook–FHIP complexes

open access: yeseLife, 2021
In eukaryotic cells, intracellular components are organized by the microtubule motors cytoplasmic dynein-1 (dynein) and kinesins, which are linked to cargos via adaptor proteins.

TRAPPC9 mediates the interaction between p150 and COPII vesicles at the target membrane. [PDF]

open access: yesPLoS ONE, 2012
The transport of endoplasmic reticulum (ER)-derived COPII vesicles toward the ER-Golgi intermediate compartment (ERGIC) requires cytoplasmic dynein and is dependent on microtubules. p150(Glued), a subunit of dynactin, has been implicated in the transport

Dynactin is Required for Microtubule Anchoring at Centrosomes [PDF]

open access: yes, 1999
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.

Evolution of the eukaryotic dynactin complex, the activator of cytoplasmic dynein

open access: yesBMC Evolutionary Biology, 2012
Background Dynactin is a large multisubunit protein complex that enhances the processivity of cytoplasmic dynein and acts as an adapter between dynein and the cargo.

Dynamic recruitment of CDK5RAP2 to centrosomes requires its association with dynein. [PDF]

open access: yesPLoS ONE, 2013
CDK5RAP2 is a centrosomal protein known to be involved in the regulation of the γ-tubulin ring complex and thus the organization of microtubule arrays. However, the mechanism by which CDK5RAP2 is itself recruited to centrosomes is poorly understood.

Mitochondrial adaptor TRAK2 activates and functionally links opposing kinesin and dynein motors

open access: yesNature Communications, 2021
Mitochondria are transported along microtubules by opposing kinesin and dynein motors. Kinesin-1 and dynein-dynactin are linked to mitochondria by TRAK proteins, but it is unclear how TRAKs coordinate these motors. We used single-molecule imaging of cell
