Mechanisms of Regulation in Intraflagellar Transport

open access: yesCells, 2022
Cilia are eukaryotic organelles essential for movement, signaling or sensing. Primary cilia act as antennae to sense a cell’s environment and are involved in a wide range of signaling pathways essential for development. Motile cilia drive cell locomotion

Myosin repertoire expansion coincides with eukaryotic diversification in the Mesoproterozoic era

open access: yesBMC Evolutionary Biology, 2017
Background The last eukaryotic common ancestor already had an amazingly complex cell possessing genomic and cellular features such as spliceosomal introns, mitochondria, cilia-dependent motility, and a cytoskeleton together with several intracellular ...

Coupling of Two Motor Proteins: a New Motor Can Move Faster [PDF]

open access: yes, 2005
We study the effect of a coupling between two motor domains in highly-processive motor protein complexes. A simple stochastic discrete model, in which the two parts of the protein molecule interact through some energy potential, is presented.

The agrin gene codes for a family of basal lamina proteins that differ in function and distribution [PDF]

open access: yes, 1992
We isolated two cDNAs that encode isoforms of agrin, the basal lamina protein that mediates the motor neuron-induced aggregation of acetylcholine receptors on muscle fibers at the neuromuscular junction.

Cortical proteins may provide motor resilience in older adults

open access: yesScientific Reports, 2021
Motor resilience proteins may be a high value therapeutic target that offset the negative effects of pathologies on motor function. This study sought to identify cortical proteins associated with motor decline unexplained by brain pathologies that ...

Modelling Molecular Motors as Folding-Unfolding Cycles [PDF]

open access: yes, 1999
We propose a model for motor proteins based on a hierarchical Hamiltonian that we have previously introduced to describe protein folding. The proposed motor model has high efficiency and is consistent with a linear load-velocity response.

The landscape of human mutually exclusive splicing

open access: yesMolecular Systems Biology, 2017
Mutually exclusive splicing of exons is a mechanism of functional gene and protein diversification with pivotal roles in organismal development and diseases such as Timothy syndrome, cardiomyopathy and cancer in humans.

Single molecule thermodynamics of ATP synthesis by F1-ATPase

open access: yesNew Journal of Physics, 2015
F _o F _1 -ATP synthase is a factory for synthesizing ATP in virtually all cells. Its core machinery is the subcomplex F _1 -motor (F _1 -ATPase) and performs the reversible mechanochemical coupling.

Aging, Alzheimer’s, and APOE genotype influence the expression and neuronal distribution patterns of microtubule motor protein dynactin-P50

open access: yesFrontiers in Cellular Neuroscience, 2015
Reports from neural cell cultures and experimental animal studies provide evidence of age- and disease-related changes in retrograde transport of spent or misfolded proteins destined for degradation or recycling. However, few studies address these issues

Symmetry Breaking and Emergence of Directional Flows in Minimal Actomyosin Cortices

open access: yesCells, 2020
Cortical actomyosin flows, among other mechanisms, scale up spontaneous symmetry breaking and thus play pivotal roles in cell differentiation, division, and motility.
