Post‐LECA Origin and Diversification of an Axonemal Outer Arm Dynein Motor
ABSTRACT Dyneins were present in the last eukaryotic common ancestor (LECA) and play key roles in eukaryotic biology. Axonemal dyneins form the inner and outer arms that power ciliary beating, and it has long been recognized that outer arms in some organisms contain two different heavy chain motors, whereas those from other species contain a third unit

The C‐Terminal Regions of TRAK Proteins Contain MIRO‐Independent Mitochondrial Localization Domains
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.

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

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

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.

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

Mechanical control of the directional stepping dynamics of the kinesin motor
Among the multiple steps constituting the kinesin's mechanochemical cycle, one of the most interesting events is observed when kinesins move an 8-nm step from one microtubule (MT)-binding site to another.

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
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.
