High throughput transcriptome profiling of lithium stimulated human mesenchymal stem cells reveals priming towards osteoblastic lineage. [PDF]

open access: yesPLoS ONE, 2013
Human mesenchymal stem cells (hMSCs) present in the bone marrow are the precursors of osteoblasts, chondrocytes and adipocytes, and hold tremendous potential for osteoregenerative therapy.

Regulation of polarised growth in fungi [PDF]

open access: yes, 2008
Polarised growth in fungi occurs through the delivery of secretory vesicles along tracks formed by cytoskeletal elements to specific sites on the cell surface where they dock with a multiprotein structure called the exocyst before fusing with the ...

Function and regulation of Rnd proteins in cortical projection neuron migration

open access: yesFrontiers in Neuroscience, 2015
The mammalian cerebral cortex contains a high variety of neuronal subtypes that acquire precise spatial locations and form long or short-range connections to establish functional neuronal circuits.

Actin re-organization induced by Chlamydia trachomatis serovar D--evidence for a critical role of the effector protein CT166 targeting Rac. [PDF]

open access: yesPLoS ONE, 2010
The intracellular bacterium Chlamydia trachomatis causes infections of urogenital tract, eyes or lungs. Alignment reveals homology of CT166, a putative effector protein of urogenital C. trachomatis serovars, with the N-terminal glucosyltransferase domain

Phytochrome regulates GTP‐binding protein activity in the envelope of pea nuclei [PDF]

open access: yesThe Plant Journal, 1993
Three GTP‐binding proteins with apparent molecular masses of 27, 28 and 30 kDa have been detected in isolated nuclei of etiolated pea plumules. After LDS‐PAGE and transfer to nitrocellulose these proteins bind [32p]GTP in the presence of excess ATP, suggesting that they are monomeric G proteins.

Vascular Growth in the Fetal Lung [PDF]

open access: yes, 2011
The structure of the lung is truly remarkable. It is primarily composed of three branched tubular networks (the airway, pulmonary artery and vein, bronchial artery and vein) which supply blood and air to the site of gas exchange and which maintain ...

Small GTP-binding protein Ran is regulated by posttranslational lysine acetylation [PDF]

open access: yesProceedings of the National Academy of Sciences, 2015
Significance The small GTPase Ran plays fundamental roles in cellular processes such as nucleo-cytoplasmic transport, mitotic spindle formation, and nuclear envelope assembly. Recently, Ran was found to be lysine acetylated, among others, in functionally important regions such as switch I and switch II.

Differential proteome analysis of pea roots at the early stages of symbiosis with nodule bacteria

open access: yesВавиловский журнал генетики и селекции, 2018
In this paper, we have analyzed changes in the proteomic spectrum of pea Pisum sativum L. roots during inoculation with rhizobial bacteria with the aim of revealing new regulators of symbiosis development. To study the changes in the proteome spectrum of

Identifying conformational changes with site-directed spin labeling reveals that the GTPase domain of HydF is a molecular switch [PDF]

open access: yes, 2017
[FeFe]-hydrogenases catalyse the reduction of protons to hydrogen at a complex 2Fe[4Fe4S] center called H-cluster. The assembly of this active site is a multistep process involving three proteins, HydE, HydF and HydG.

Phosphatidylinositol (4,5)-bisphosphate turnover by INP51 regulates the cell wall integrity pathway in "Saccharomyces cerevisiae" [PDF]

open access: yes, 2004
Signal transduction pathways are important for the cell to transduce external or internal stimuli where second messengers play an important role as mediators of the stimuli. One important group of second messengers are the phosphoinositide family present
