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.

Kinesin-8B controls basal body function and flagellum formation and is key to malaria transmission.
, 2020 Eukaryotic flagella are conserved microtubule-based organelles that drive cell motility. Plasmodium, the causative agent of malaria, has a single flagellate stage: the male gamete in the mosquito.

PROTEOMICS, EarlyView.ABSTRACT Triple‐negative breast cancer (TNBC) represents the most aggressive subtype with limited therapeutic options and the poorest clinical outcomes. Using high‐resolution nUPLC‐QTOF‐MS/MS, we performed comprehensive proteomic profiling of TNBC cell lines representing disease progression stages: HCC‐1937 (stage IIB), HCC‐1599 (stage IIIA), and MDA ...

Dissection of Kinesin's Processivity
PLoS ONE, 2009 The protein family of kinesins contains processive motor proteins that move stepwise along microtubules. This mechanism requires the precise coupling of the catalytic steps in the two heads, and their precise mechanical coordination. Here we show that these functionalities can be uncoupled in chimera of processive and non-processive kinesins. A chimera

Kinesin-Driven Active Substrate Giving Stochastic Mechanical Stimuli to Cells for Characterization
, 2016 We present a new platform to give stochastic mechanical stimuli to cells for their characterization. There nano- and micrometer scaled fluctuations are generated by an engineered motor protein system of kinesin-microtubules (MTs) on a solid surface ...

Proteins: Structure, Function, and Bioinformatics, EarlyView.ABSTRACT Allosteric communication is fundamental to the function of proteins, but identifying the residue‐level pathways through which signals travel and their directionality is still a major challenge. Here we present a multi‐metric information‐theoretic framework that identifies candidate allosteric communication pathways from a single protein ...

Simulating the kinesin walk : towards a definitive theory [PDF]
Dementia is a set of incurable, fatal diseases characterised by irreversible degeneration of the brain. One theory of its cause is the failure of intracellular transport in the axons of the neurons that compose the brain.

Kinesin-8X shows ATPase, gliding motor and depolymerization activities.
, 2019 (A) Schematic protein organisation of PBANKA_0805900 (Pbkinesin-8X) and PF3D7_0319400 (Pfkinesin-8X) showing their full-length sequence and central location of the motor domain, Pbkinesin-8X (green) and Pfkinesin-8X (blue).

Phytotherapy Research, EarlyView.ABSTRACT Vascular dementia (VaD), accounting for up to 20% of dementia cases globally, is primarily driven by chronic cerebral hypoperfusion (CCH), which leads to progressive cognitive impairment. Despite the increasing prevalence of VaD, effective treatments remain limited.
