Cytoplasmic dynein transports cargoes for a variety of crucial cellular functions. However, since dynein is essential in most eukaryotic organisms, the in-depth study of the cellular function of dynein via genetic analysis of dynein mutations has not ...

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).

In Vivo Cytoskeletal AMPA Receptor Transport Imaging in C. elegans
ABSTRACT Long‐distance intracellular transport of ionotropic glutamate receptors (iGluRs) is essential for proper excitatory synaptic function underlying learning and memory. Many neuropsychiatric and neurodegenerative conditions have abnormal iGluR transport and trafficking, leading to an intense interest in the mechanisms and factors regulating these

Molecular basis for dyneinopathies reveals insight into dynein regulation and dysfunction
Cytoplasmic dynein plays critical roles within the developing and mature nervous systems, including effecting nuclear migration, and retrograde transport of various cargos.

Dyneins Motor on in Plants [PDF]
A recent report based on analysis of the Arabidopsis genome suggested that angiosperms do not contain the dynein microtubule motor. However, examination of the whole genome shotgun sequence for rice (Oryza sativa) has revealed that four dynein heavy chains are present in this monocot, indicating that the apparent lack of these sequences in Arabidopsis

ABSTRACT Cooperativity between cytoskeletal proteins is crucial for spatiotemporal coordination in biological processes, like oogenesis. In mammalian and Drosophila oogenesis, proper assembly and function of actin networks require coordination between actin assembly factors Spire and formins, as well as actin‐associated proteins like myosins and Rab ...

Mechanical Properties of Inner-Arm Dynein-F (Dynein I1) Studied With In Vitro Motility Assays [PDF]
Inner-arm dynein-f of Chlamydomonas flagella is a heterodimeric dynein. We performed conventional in vitro motility assays showing that dynein-f translocates microtubules at the comparatively low velocity of ∼1.2μm/s. From the dependence of velocity upon

C‐Terminal Tail Elongation Adds a New Dimension to the Tubulin Code
ABSTRACT Tubulin C‐terminal tails undergo diverse post‐translational modifications that regulate microtubule interactions with motors and severing enzymes. TTLL11, a member of the tubulin tyrosine ligase‐like (TTLL) family, uniquely catalyzes glutamate addition to the terminal α‐carboxyl group of both α‐ and β‐primary tubulin tails.

Lissencephaly-1 promotes the recruitment of dynein and dynactin to transported mRNAs [PDF]
Microtubule-based transport mediates the sorting and dispersal of many cellular components and pathogens. However, the mechanisms by which motor complexes are recruited to and regulated on different cargos remain poorly understood.

The Kinesin Speed Paradox Revisited: How Can Cargoes Move Faster Than Their Motors?
ABSTRACT Intracellular transport is essential for cellular organization and function. Kinesin‐1, the founding member of the kinesin superfamily, delivers a wide range of cargoes along microtubules. Since its discovery, extensive work has identified cargo–kinesin interactions and regulatory mechanisms.
