Characterization of microtubules and motor proteins via molecular dynamics simulations. [PDF]

open access: yes, 2006
Microtubules and related motor proteins such as kinesins or dyneins are cytoskeleton structures in many different physiological processes in eukaryotes.

Active spiralling of microtubules driven by kinesin motors

open access: yesScientific Reports
Cytoskeletal filaments propelled by surface-bound motor proteins can be viewed as active polymers, a class of active matter. When constraints are imposed on their movements, the propelled cytoskeletal filaments show dynamic patterns distinct from ...

Reconstitution of dynein transport to the microtubule plus end by kinesin

open access: yeseLife, 2014
Cytoplasmic dynein powers intracellular movement of cargo toward the microtubule minus end. The first step in a variety of dynein transport events is the targeting of dynein to the dynamic microtubule plus end, but the molecular mechanism underlying this

Non-ciliary Roles of IFT Proteins in Cell Division and Polycystic Kidney Diseases

open access: yesFrontiers in Cell and Developmental Biology, 2020
Cilia are small organelles present at the surface of most differentiated cells where they act as sensors for mechanical or biochemical stimuli. Cilia assembly and function require the Intraflagellar Transport (IFT) machinery, an intracellular transport ...

The Common Functional Dynamics of Molecular Motor and Switch Proteins [PDF]

open access: yesBiophysical Journal, 2013
Understanding how protein ligand binding can promote distinct conformational states, with different affinities for binding partners, is key to understanding the structural basis of protein efficacy. Here we study eight molecular motor and G-protein families that undergo GTP or ATP associated conformational changes to regulate important cell processes ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Vaccinia protein F12 has structural similarity to kinesin light chain and contains a motor binding motif required for virion export.

open access: yesPLoS Pathogens, 2010
Vaccinia virus (VACV) uses microtubules for export of virions to the cell surface and this process requires the viral protein F12. Here we show that F12 has structural similarity to kinesin light chain (KLC), a subunit of the kinesin-1 motor that binds ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

S. pombe kinesins-8 promote both nucleation and catastrophe of microtubules [PDF]

open access: yes, 2012
The kinesins-8 were originally thought to be microtubule depolymerases, but are now emerging as more versatile catalysts of microtubule dynamics. We show here that S.

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

open access: yesFEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.
