Functional specialization of the yeast Rho1 GTP exchange factors [PDF]
Rho GTPases are regulated in complex spatiotemporal patterns that may be dependent, in part at least, on the multiplicity of their GTP exchange factors (GEFs).

Cytokinesis mechanics and mechanosensing [PDF]
AbstractCytokinesis shape change occurs through the interfacing of three modules, cell mechanics, myosin II‐mediated contractile stress generation and sensing, and a control system of regulatory proteins, which together ensure flexibility and robustness.

The Toxoplasma gondii active serine hydrolase 4 regulates parasite division and intravacuolar parasite architecture [PDF]
Hydrolase are enzymes that regulate diverse biological processes, including posttranslational protein modifications. Recent work identified four active serine hydrolases (ASHs) in Toxoplasma gondii as candidate depalmitoylases. However, only TgPPT1 (ASH1)

Functional characterization of the diatom cyclin-dependent kinase A2 as a mitotic regulator reveals plant-like properties in a non-green lineage [PDF]
Background: Cyclin-dependent kinases (CDKs) are crucial regulators of cell cycle progression in eukaryotes. The diatom CDKA2 was originally assigned to the classical A-type CDKs, but its cell cycle phase-specific transcription at the G2-to-M phase ...

Immunolocalization of dually phosphorylated MAPKs in dividing root meristem cells of Vicia faba, Pisum sativum, Lupinus luteus and Lycopersicon esculentum [PDF]
Key message In plants, phosphorylated MAPKs display constitutive nuclear localization; however, not all studied plant species show co-localization of activated MAPKs to mitotic microtubules.

The developmental cell biology of Trypanosoma brucei [PDF]
Trypanosoma brucei provides an excellent system for studies of many aspects of cell biology, including cell structure and morphology, organelle positioning, cell division and protein trafficking. However, the trypanosome has a complex life cycle in which

TSO1 functions in cell division during Arabidopsis flower development [PDF]
We describe an Arabidopsis mutant, tso1, which develops callus-like tissues in place of floral organs. The tso1 floral meristem lacks properly organized three cell layers, and the nuclei of these cells are irregular in size and shape.

Low doses of ochratoxin A induce micronucleus formation and delay DNA repair in human lymphocytes [PDF]
The contamination of food commodities by fungal toxins has attracted great interest because many of these mycotoxins are responsible for different diseases, including cancer and other chronic illnesses. Ochratoxin A (OTA) is a mycotoxin naturally present

Bem1p contributes to secretory pathway polarization through a direct interaction with Exo70p. [PDF]
The exocyst serves to tether secretory vesicles to cortical sites specified by polarity determinants, in preparation for fusion with the plasma membrane.

Afadin orients cell division to position the tubule lumen in developing renal tubules [PDF]
In many types of tubules, continuity of the lumen is paramount to tubular function, yet how tubules generate lumen continuity in vivo is not known. We recently found the F-actin binding protein Afadin is required for lumen continuity in developing renal ...
