Under nutrient-deficient conditions, the yeast S. cerevisiae sequesters its own cytoplasmic components into vacuoles in the form of "autophagic bodies" (Takeshige, K., M. Baba, S. Tsuboi, T. Noda, and Y. Ohsumi. 1992. J. Cell Biol. 119:301-311). Immunoelectron microscopy showed that two cytosolic marker enzymes, alcohol dehydrogenase and phosphoglycerate… (More)
We have cloned the cDNA encoding human PICK1 (protein interacting with C kinase 1), a PDZ domain-containing protein of 415 amino acids, and also identified the Drosophila homologue by search of the databank. Northern blot analysis shows a single mRNA of about 2.0 kb ubiquitously expressed in human tissues. Although PICK1 proteins harbor a region homologous… (More)
Isolated mitochondria supplemented with succinate or NAD(+)-linked substrates generate hydrogen peroxide (H2O2) in State 4 and the generation is enhanced by antimycin A, an inhibitor of the respiratory chain. Superoxide is a stoichiometric precursor of mitochondrial H2O2 because the ratio of O2-/H2O2 generation rates is close to 2.0 and is generated by an… (More)
The Computer Animation Festival issued a special call for short animations of our robot mascot character. Students and professionals around the world submitted many creative, entertaining animations. The largest group of submissions came from students at the Digital Hollywood school in Tokyo.
1 Novel excitatory neuropeptides isolated from a prosobranch gastropod, Thais clavigera: The molluscan counterpart of the annelidan GGNG peptides Abstract The GGNG peptides are excitatory neuropeptides identified from earthworms, leeches and polychaeta. Two structurally related peptides were purified and characterized from a mollusk, Thais clavigera… (More)
The GGNG peptides are excitatory neuropeptides identified from earthworms, leeches and polychaeta. Two structurally related peptides were purified and characterized from a mollusk, Thais clavigera (prosobranch gastropod). The peptides designated as Thais excitatory peptide-1 (TEP-1) (KCSGKWAIHACWGGN-NH2) and TEP-2 (KCYGKWAMHACWGGN-NH2) are pentadecapeptides… (More)
