Cytoskeleton, EarlyView.ABSTRACT Of the three types of cytoskeleton known in animals—actin, microtubules, and intermediate filaments—only actin and microtubules exist in plants. Both play important roles in cellular shaping, organelle movement, organization of the endomembrane system, and cell signaling.

Cargo specificity, regulation, and therapeutic potential of cytoplasmic dynein
Experimental and Molecular MedicineIntracellular retrograde transport in eukaryotic cells relies exclusively on the molecular motor cytoplasmic dynein 1. Unlike its counterpart, kinesin, dynein has a single isoform, which raises questions about its cargo specificity and regulatory ...

iScience, 2022 Summary: In the axon terminal, microtubule stability is decreased relative to the axon shaft. The dynamic microtubule plus ends found in the axon terminal have many functions, including serving as a docking site for the Cytoplasmic dynein motor. Here, we

Making Two out of One: Kinesin Motors Driving Plant Cell Division
Cytoskeleton, EarlyView.ABSTRACT The Kinesin superfamily of microtubule dependent motors is present in all eukaryotes. Not all of the subfamilies are represented in all kingdoms, and the ones that are do not always show conserved functions. Tight control of the cytoskeleton is essential for proper progression and completion of mitosis and cytokinesis, and key functions are ...

Cytoskeleton, EarlyView.ABSTRACT Microtubules play essential roles in numerous cellular processes. All microtubules are built from the protein tubulin, yet individual microtubules can differ spatially and temporally due to their tubulin isotype composition and post‐translational modifications (PTMs).

Neuronal migration defects in the Loa dynein mutant mouse
Neural Development, 2011 Background Cytoplasmic dynein and its regulatory proteins have been implicated in neuronal and non-neuronal cell migration. A genetic model for analyzing the role of cytoplasmic dynein specifically in these processes has, however, been lacking.

BICD2 phosphorylation regulates dynein function and centrosome separation in G2 and M
Nature Communications, 2023 The activity of dynein is regulated by a number of adaptors that mediate its interaction with dynactin, effectively activating the motor complex while also connecting it to different cargos.

Dynein Swings into Action [PDF]
Cell, 2009 Motor proteins, such as dynein, use chemical energy from ATP hydrolysis to move along the cytoskeleton. Roberts et al. (2009) now describe the arrangement of subdomains in the motor domain of dynein and propose a model for how these regions function together in force generation.

The C‐Terminal Regions of TRAK Proteins Contain MIRO‐Independent Mitochondrial Localization Domains
Cytoskeleton, EarlyView.ABSTRACT Current models suggest that MIRO GTPases anchor cytoskeletal motors to the mitochondrial outer membrane (MOM). However, our previous findings indicate that the unconventional myosin, MYO19, interacts with MIRO weakly and that a MIRO‐independent MOM‐localizing domain interacts more tightly with the MOM.

NuMA recruits dynein activity to microtubule minus-ends at mitosis
eLife, 2017 To build the spindle at mitosis, motors exert spatially regulated forces on microtubules. We know that dynein pulls on mammalian spindle microtubule minus-ends, and this localized activity at ends is predicted to allow dynein to cluster microtubules into
