NEURONIC SYSTEM INSIDE NEURONS: MOLECULAR BIOLOGY AND BIOPHYSICS OF NEURONAL MICROTUBULES [PDF]

open access: yes, 2004
Neurons are highly specialized cells that input, process, store and output information. Interneuronal communication is achieved in four basic ways: (i) Ca2+ evoked exocytosis with chemical neurotransmission, (ii) gap junction electrotonic coupling, (iii)

Kinesin-5 inhibitor resistance is driven by kinesin-12 [PDF]

open access: yesJournal of Cell Biology, 2016
The microtubule (MT) cytoskeleton bipolarizes at the onset of mitosis to form the spindle. In animal cells, the kinesin-5 Eg5 primarily drives this reorganization by actively sliding MTs apart. Its primacy during spindle assembly renders Eg5 essential for mitotic progression, demonstrated by the lethal effects of kinesin-5/Eg5 inhibitors (K5Is ...

The crowding dynamics of the motor protein kinesin-II.

open access: yesPLoS ONE, 2020
Intraflagellar transport (IFT) in C. elegans chemosensory cilia is an example of functional coordination and cooperation of two motor proteins with distinct motility properties operating together in large groups to transport cargoes: a fast and ...

Functional characterisation and drug target validation of a mitotic kinesin-13 in Trypanosoma brucei. [PDF]

open access: yesPLoS Pathogens, 2010
Mitotic kinesins are essential for faithful chromosome segregation and cell proliferation. Therefore, in humans, kinesin motor proteins have been identified as anti-cancer drug targets and small molecule inhibitors are now tested in clinical studies ...

Surface topography of microtubule walls decorated with monomeric and dimeric kinesin constructs [PDF]

open access: yes, 2000
The surface topography of opened-up microtubule walls (sheets) decorated with monomeric and dimeric kinesin motor domains was investigated by freeze-drying and unidirectional metal shadowing.

Chromosome 20q Amplification Regulates Response to Kinesin-5 Inhibitor

open access: yesCancer Informatics, 2008
We identified gene expression signatures predicting responsiveness to a Kinesin-5 (KIF11) inhibitor (Kinesin-5i) in cultured colon tumor cell lines.

Jump-starting kinesin [PDF]

open access: yesThe 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 ...

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

The kinesin walk: a dynamic model with elastically coupled heads

open access: yes, 1998
Recently individual two-headed kinesin molecules have been studied in in vitro motility assays revealing a number of their peculiar transport properties. In this paper we propose a simple and robust model for the kinesin stepping process with elastically

Intercompartmental communication in senescence

open access: yesFEBS Open Bio, EarlyView.
Senescent cells experience structural changes in the plasma membrane, endoplasmic reticulum, mitochondria, lysosomes, nucleus, and cytoskeleton. These alterations disrupt crosstalk among cellular compartments, impairing vesicular trafficking, contact sites, and molecular flow.
