The role of dynamin and so-called accessory proteins in endocytosis is well established. However, molecular details of the function(s) of dynamin II at the Golgi are largely unclear. We demonstrate that the ubiquitously expressed syndapin II isoform interacts with the proline-rich domain (PRD) of dynamin II through its Src-homology 3 (SH3) domain.(More)
The biological effects of rare-earth metal ions on the organism have been studied using La3+ as a probe ion and Escherichia coli cell as a target organism. Atomic force microscopy (AFM) studies reveal that La3+ substantially changes the structure of the outer cell membrane responsible for the cell permeability. Significant damages of the outer cell membrane(More)
Doppel (Dpl) is a prion protein paralog that causes neurodegeneration when expressed ectopically in the brain. To investigate the cellular mechanism underlying this effect, we analyzed Dpl-expressing transgenic mice in which the gene for the proapoptotic protein Bax had been deleted. We found that Bax deletion does not alter either clinical symptoms or(More)
Prion diseases are fatal neurodegenerative disorders that result from conversion of a normal, cell surface glycoprotein (PrP(C)) into a conformationally altered isoform (PrP(Sc)) that is thought to be infectious. Although a great deal is known about the role of PrP(Sc) in the disease process, the physiological function of PrP(C) has remained enigmatic. In(More)
Flavonols are plant pigments that are ubiquitous in nature. Morin and other related plant flavonols have come into recent prominence because of their usefulness as anticancer, anti-tumor, anti-AIDS, and other important therapeutic activities of significant potency and low systemic toxicity. The heat of combustion of morin (molecular formula, C15H10O7·H2O)(More)
