In Vivo Cytoskeletal AMPA Receptor Transport Imaging in C. elegans

Cytoskeleton, 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

Protocol for Reconstituting Adaptor‐Mediated Activation of Full‐Length Kinesin‐1

Cytoskeleton, EarlyView.
ABSTRACT Kinesin‐1 is a member of the kinesin superfamily that plays an essential role in intracellular cargo transport. In the absence of cargo, Kinesin‐1 exhibits low motor activity due to autoinhibition. Multiple studies have demonstrated that adaptor proteins, which link cargos to Kinesin‐1, can activate Kinesin‐1 by releasing the autoinhibition ...

Integrative genomic analysis identifies associations of molecular alterations to APOBEC and BRCA1/2 mutational signatures in breast cancer

Molecular Genetics & Genomic Medicine, 2019
Background The observed mutations in cancer are the result of ~30 mutational processes, which stamp particular mutational signatures (MS). Nevertheless, it is still not clear which genomic alterations correlate to several MS.

The conformational cycle of kinesin

Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 2000
The stepping mechanism of kinesin can be thought of as a programme of conformational changes. We briefly review protein chemical, electron microscopic and transient kinetic evidence for conformational changes, and working from this evidence, outline a model for the mechanism. In the model, both kinesin heads initially trap Mg.ADP.

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

Cytoskeleton, 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 ...

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

Cytoskeleton, 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.

Mutations in the KIF21B kinesin gene cause neurodevelopmental disorders through imbalanced canonical motor activity

Nature Communications, 2020
Kinesins regulate intracellular transport and microtubule dynamics. Here, the authors show that KIF21B variants in humans associate with corpus callosum agenesis and microcephaly.

Microtubule Destabilizing Kinesins: A Historical Perspective and Thoughts for the Future

Cytoskeleton, EarlyView.
ABSTRACT The microtubule cytoskeleton plays critical roles in multiple cellular processes such as mitotic spindle assembly and chromosome segregation. Cells contain a number of microtubule‐associated proteins that regulate microtubule dynamics both temporally and spatially in cells. The microtubule depolymerizing kinesins include members of the Kinesin‐

Jump-starting kinesin [PDF]

The Journal of Cell Biology, 2007
When it is not actively transporting cargo, conventional Kinesin-1 is present in the cytoplasm in a folded conformation that cannot interact effectively with microtubules (MTs). Two important and largely unexplored aspects of kinesin regulation are how it is converted to an active species when bound to cargo and the related issue of how kinesin ...

A WGCNA‐Based Approach to Identify Hub Genes Associated With TNM Staging in Urothelial Bladder Carcinoma

Cancer Nexus, EarlyView.
ABSTRACT In this study, we identified gene modules and representative candidate biomarkers linked to clinical progression in patients with UBC. Weighted gene co‐expression network analysis (WGCNA) was used to identify gene modules associated with TNM staging in UBC patients.
