A bacteriophage tubulin harnesses dynamic instability to center DNA in infected cells. [PDF]

open access: yes, 2014
Dynamic instability, polarity, and spatiotemporal organization are hallmarks of the microtubule cytoskeleton that allow formation of complex structures such as the eukaryotic spindle. No similar structure has been identified in prokaryotes.

Ras inhibitors gate chemoattractant concentration range for chemotaxis through controlling GPCR-mediated adaptation and cell sensitivity

open access: yesFrontiers in Immunology, 2022
Chemotaxis plays an essential role in recruitment of leukocytes to sites of inflammation. Eukaryotic cells sense chemoattractant with G protein-coupled receptors (GPCRs) and chemotax toward gradients with an enormous concentration range through ...

A latent ability to persist: differentiation in Toxoplasma gondii [PDF]

open access: yes, 2018
A critical factor in the transmission and pathogenesis of Toxoplasma gondii is the ability to convert from an acute disease-causing, proliferative stage (tachyzoite), to a chronic, dormant stage (bradyzoite).

SF3b4: A Versatile Player in Eukaryotic Cells

open access: yesFrontiers in Cell and Developmental Biology, 2020
Spliceosomes are large protein-RNA complexes regulating pre-mRNA processing in eukaryotes. SF3b4 encodes a core subunit of the U2-type spliceosome, loss- or gain-of-function of which often associates with abnormal cell growth, leading to tumorigenesis ...

Functional capacity of Shiga-toxin promoter sequences in eukaryotic cells. [PDF]

open access: yesPLoS ONE, 2013
Shiga toxins (Stx) are the main virulence factors in enterohemorrhagic Escherichia coli (EHEC) infections, causing diarrhea and hemolytic uremic syndrome (HUS). The genes encoding for Shiga toxin-2 (Stx2) are located in a bacteriophage.

The Unicellular State as a Point Source in a Quantum Biological System. [PDF]

open access: yes, 2016
A point source is the central and most important point or place for any group of cohering phenomena. Evolutionary development presumes that biological processes are sequentially linked, but neither directed from, nor centralized within, any specific ...
