Cytoskeleton, 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).

The characterisation of family-13 kinesins in Trypanosoma brucei [PDF]
, 2008 Kinesins are motor proteins involved in the movement of organelles and sub-organelles along microtubule tracks within the cell. Phylogenetic analysis of the 46 kinesin genes coded by the Trypanosoma brucei genome resulted in the grouping of seven kinesin

Heterogeneity in kinesin function [PDF]
Traffic, 2017 The kinesin family proteins are often studied as prototypical molecular motors; a deeper understanding of them can illuminate regulation of intracellular transport. It is typically assumed that they function identically. Here we find that this assumption of homogeneous function appears incorrect: variation among motors’ velocities in vivo and in vitro ...

The run length of transport by several kinesins is shown.
, 2015 (a) shows the run length of one, two, and three kinesins for [ATP] = 2 mM. (b) shows an example of HLB when a resisting load of 12 pN acts on the cargo. (b1) The leading kinesin is stationary while waiting for ATP.

Cytoskeleton, EarlyView.ABSTRACT Post‐translational modifications (PTMs) to tubulin subunits in microtubule filaments are thought to comprise a component of the tubulin code that specifies microtubule functions in cell physiology and animal development. Acetylation of Lysine‐40 (K40) on α‐tubulin (αTub‐K40ac) and glutamylation of both α‐ and β‐tubulin are two tubulin PTMs of ...

Post‐LECA Origin and Diversification of an Axonemal Outer Arm Dynein Motor
Cytoskeleton, EarlyView.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

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

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.

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 ...
