In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Protein kinase D enzymes are dispensable for proliferation, survival and antigen receptor-regulated NFκB activity in vertebrate B-cells [PDF]
To investigate the importance of protein kinase D (PKD) enzymes we generated a PKD-null DT40 B-lymphocyte cell line. Previously we have shown that PKDs have an essential role in regulating class II histone deacetylases in DT40 B-cells [Matthews, S.A ...

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Regulation der humanen Aurora-A Kinase und Identifikation potentieller Interaktionspartner [PDF]
The error-free segregation of duplicated chromosomes during cell division is essential for the maintenance of an intact genome. This process is brought about by a highly dynamic bipolar array of microtubules, the mitotic spindle.

Functional analysis of the "Saccharomyces cerevisiae" Npr1 protein kinase [PDF]
The uptake and processing of nutrients is highly regulated. Cells adapt to changes of the availability of nutrients to provide a complete set of transporters and metabolizing enzymes for optimal use of the available nutrients.

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane
Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.

Solid Phase Peptide Synthesis: Analysis and Identification of Protein Kinase Substrates [PDF]
This research study examines the synthesis of tyrosine containing peptides based on the protein paxillin. Paxillin is a proposed substrate of the Focal Adhesion Kinase (FAK) protein tyrosine kinase.

Structural and functional characterization of the intracellular kinase domain of vascular endothelial growth factor receptor-2 [PDF]
Vascular Endothelial Growth Factors (VEGFs) are key players in blood and lymphatic vessel development and homeostasis. The family consists of five members, VEGF-A, -B, -C, -D and placenta growth factor (PLGF).

Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Structural and functional studies on nucleotide binding to AMP-activated protein kinase [PDF]
AMP-activated protein kinase (AMPK) is an enzyme that senses and regulates cellular energy balance thus playing a key role in homeostasis. As such it is a target for treatment of metabolic disorders such as type II diabetes.
