Prolyl Isomerase Pin1 Regulates the Stability of Hepatitis B Virus Core Protein
The dynamic interplay between virus and host proteins is critical for establishing efficient viral replication and virus-induced pathogenesis. Phosphorylation-dependent prolyl isomerization by Pin1 provides a unique mechanism of molecular switching to ...

Neurological, Psychiatric, and Biochemical Aspects of Thiamine Deficiency in Children and Adults. [PDF]
Thiamine (vitamin B1) is an essential nutrient that serves as a cofactor for a number of enzymes, mostly with mitochondrial localization. Some thiamine-dependent enzymes are involved in energy metabolism and biosynthesis of nucleic acids whereas others ...

The metabolic advantage of tumor cells
1- Oncogenes express proteins of "Tyrosine kinase receptor pathways", a receptor family including insulin or IGF-Growth Hormone receptors. Other oncogenes alter the PP2A phosphatase brake over these kinases.

Purification and Characterization of Pyruvate‐Dehydrogenase Phosphatase from Pig‐Heart Muscle [PDF]
Pyruvate‐dehydrogenase phosphatase was extensively purified from pig heart muscle. The molecular weight was determined to be in the range between 92000 and 95000. By dodecylsulfate‐gel electrophoresis there was no indication for a subunit structure of the protein. The phosphatase is dependent on Mg2+ or Mn2+.

Post-translational deregulation of YAP1 is genetically controlled in rat liver cancer and determines the fate and stem-like behavior of the human disease [PDF]
Previous studies showed that YAP1 is over-expressed in hepatocellular carcinoma (HCC). Here we observed higher expression of Yap1/Ctgf axis in dysplastic nodules and HCC chemically-induced in F344 rats, genetically susceptible to hepatocarcinogenesis ...

Ptc6 is required for proper rapamycin-induced down-regulation of the genes coding for ribosomal and rRNA processing proteins in S. cerevisiae. [PDF]
Ptc6 is one of the seven components (Ptc1-Ptc7) of the protein phosphatase 2C family in the yeast Saccharomyces cerevisiae. In contrast to other type 2C phosphatases, the cellular role of this isoform is poorly understood. We present here a comprehensive
