Electrostatically biased binding of kinesin to microtubules [PDF]

, 2011
The minimum motor domain of kinesin-1 is a single head. Recent evidence suggests that such minimal motor domains generate force by a biased binding mechanism, in which they preferentially select binding sites on the microtubule that lie ahead in the ...

Nerve terminal degeneration is independent of muscle fiber genotype in SOD1 mice. [PDF]

PLoS ONE, 2010
Motor neuron degeneration in SOD1(G93A) transgenic mice begins at the nerve terminal. Here we examine whether this degeneration depends on expression of mutant SOD1 in muscle fibers.Hindlimb muscles were transplanted between wild-type and SOD1(G93A ...

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

FEBS 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 ...

Rab11A-controlled assembly of the inner membrane complex is required for completion of apicomplexan cytokinesis [PDF]

, 2009
The final step during cell division is the separation of daughter cells, a process that requires the coordinated delivery and assembly of new membrane to the cleavage furrow.

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Multiple functions of LIM domain-binding CLIM/NLI/Ldb cofactors during zebrafish development

, 2002
The crucial involvement of CLIM/NLI/Ldb cofactors for the exertion of the biological activity of LIM homeodomain transcription factors (LIM-HD) has been demonstrated.

Phosphorylation of mitotic kinesin-like protein 2 by polo-like kinase 1 is required for cytokinesis [PDF]

, 2003
We have investigated the function of mitotic kinesin-like protein (MKlp) 2, a kinesin localized to the central spindle, and demonstrate that its depletion results in a failure of cleavage furrow ingression and cytokinesis, and disrupts localization of ...

Motor proteins of the eukaryotic cytoskeleton [PDF]

Proceedings of the National Academy of Sciences, 1997
Motility is a hallmark of life. Even cells that are incapable of active movement within their environment perform essential intracellular motility processes. A number of mechanisms have evolved to generate the mechanical forces required to drive biological motility.

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

FEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

Structural Studies on Bacteriophage Portal Proteins [PDF]

, 2013
In tailed bacteriophages and evolutionarily related herpes viruses, the portal protein is a central component of the DNA packaging molecular motor, which translocates viral genomic DNA into a preformed procapsid.
