The medaka is becoming an attractive model organism for the study of vertebrate early development and organogenesis and large-scale mutagenesis projects that are aimed at creating developmentally defective mutants are now being conducted by several groups in Japan. To strengthen the study of medaka developmental genetics, we have conducted a large-scale(More)
Identifying intracellular molecular interactions is the first step toward understanding complex dynamics and mechanisms of the cell. We have created a comprehensive map of molecular interactions in a macrophage based on published literature. The map was created to analyze the experimental data sets produced by the Alliance for Cellular Signaling (AfCS).(More)
SR-protein kinases (SRPKs) and their substrates, serine/arginine-rich pre-mRNA splicing factors, are key components of splicing machinery and are well conserved across phyla. Despite extensive biochemical investigation, the physiological functions of SRPKs remain unclear. In the present study, cDNAs for SPK-1, a C. elegans SRPK homologue, and CeSF2, an(More)
After the launch of dipeptidyl peptidase-4 (DPP-4), a new oral hypoglycemic drug (OHD), in December 2009, severe hypoglycemia cases were reported in Japan. Although the definite cause was unknown, co-administration with sulfonylureas (SU) was suspected as one of the potential risk factors. The Japan Association for Diabetes Education and Care (JADEC)(More)

Voltage-dependent K(+) (Kv) channels play crucial roles in nerve and muscle action potentials. Voltage-sensing domains (VSDs) of Kv channels sense changes in the transmembrane potential, regulating the K(+)-permeability across the membrane. Gating modifier toxins, which have been used for the functional analyses of Kv channels, inhibit Kv channels by(More)
Voltage-dependent potassium (Kv) channels allow for the selective permeability of potassium ions in a membrane potential dependent manner, playing crucial roles in neurotransmission and muscle contraction. Kv channel is a tetramer, in which each subunit possesses a voltage-sensing domain (VSD) and a pore domain (PD). Although several lines of evidence(More)
