Structure and Mechanics of Dynein Motors [PDF]

open access: yes, 2021
Dyneins make up a family of AAA+ motors that move toward the minus end of microtubules. Cytoplasmic dynein is responsible for transporting intracellular cargos in interphase cells and mediating spindle assembly and chromosome positioning during cell ...

Purification, Fluorescent Labeling, and Detyrosination of Mammalian Cell Tubulin for Biochemical Assays

open access: yesCytoskeleton, 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).

Cryo-EM shows how dynactin recruits two dyneins for faster movement

open access: yes, 2017
Dynein and its cofactor dynactin form a highly processive microtubule motor in the presence of an activating adaptor, such as BICD2. Different adaptors link dynein/dynactin to distinct cargos.

Three-dimensional flagella structures from animals’ closest unicellular relatives, the Choanoflagellates

open access: yeseLife, 2022
In most eukaryotic organisms, cilia and flagella perform a variety of life-sustaining roles related to environmental sensing and motility. Cryo-electron microscopy has provided considerable insight into the morphology and function of flagellar structures,

In Vivo Cytoskeletal AMPA Receptor Transport Imaging in C. elegans

open access: yesCytoskeleton, EarlyView.
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

The Influence of Drosophila Spire and Myosin V During Mid‐Oogenesis Is Independent of Their Direct Interaction

open access: yesCytoskeleton, EarlyView.
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 ...

Dyneins Motor on in Plants [PDF]

open access: yesTraffic, 2002
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

Two-headed outer- and inner-arm dyneins of Leishmania sp bear conserved IQ-like motifs

open access: yes, 2015
Dyneins are high molecular weight microtubule based motor proteins responsible for beating of the flagellum. The flagellum is important for the viability of trypanosomes like Leishmania.

C‐Terminal Tail Elongation Adds a New Dimension to the Tubulin Code

open access: yesCytoskeleton, EarlyView.
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.

Molecular mechanisms of the interhead coordination by interhead tension in cytoplasmic dyneins

open access: yes, 2018
Cytoplasmic dyneins play a major role in retrograde cellular transport by moving vesicles and organelles along microtubule filaments. Dyneins are multidomain motor proteins with two heads that coordinate their motion via their interhead tension. Compared
