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 ...

Insight into microtubule disassembly by kinesin-13s from the structure of Kif2C bound to tubulin

Nature Communications, 2017
Kinesin-13s are microtubule depolymerizing enzymes. Here the authors present the crystal structure of a DARPin fused construct comprising the short neck region and motor domain of kinesin-13 in complex with an αβ-tubulin heterodimer, which shows that ...

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 ...

Effect of 2-H and 18-O water isotopes in kinesin-1 gliding assay [PDF]

, 2012
We show here the effects of heavy-hydrogen water (^2^H~2~O) and heavy-oxygen water (H~2~^18^O) on the gliding speed of microtubules on kinesin-1 coated surfaces.

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.

A mutual co-recognition mechanism ensures the proper assembly of heterotrimeric kinesin-2 for intraflagellar transport

Nature Communications
Heterotrimeric kinesin-2, composed of two distinct kinesin motors and a kinesin-associated protein (KAP), is essential for intraflagellar transport and ciliogenesis.

Localization and function of Kinesin-5-like proteins during assembly and maintenance of mitotic spindles in Silvetia compressa

BMC Research Notes, 2009
Background Kinesin-5 (Eg-5) motor proteins are essential for maintenance of spindle bipolarity in animals. The roles of Kinesin-5 proteins in other systems, such as Arabidopsis, Dictyostelium, and sea urchin are more varied.

Mechanism of Processive Movement of Monomeric and Dimeric Kinesin Molecules

International Journal of Biological Sciences, 2010
Kinesin molecules are motor proteins capable of moving along microtubule by hydrolyzing ATP. They generally have several forms of construct. This review focuses on two of the most studied forms: monomers such as KIF1A (kinesin-3 family) and dimers such ...
