Synaptic scaffolding molecule (S-SCAM) is a synaptic protein, which harbors five or six PSD-95/Discs large/ZO-1 (PDZ), a guanylate kinase and two WW domains. It interacts with NMDA receptor subunits, neuroligin and beta-catenin, and is involved in the accumulation of neuroligin at excitatory synapses. In this study, we have demonstrated S-SCAM is localized(More)
Synaptic scaffolding molecule (S-SCAM) interacts with a wide variety of molecules at excitatory and inhibitory synapses. It comprises three alternative splicing variants, S-SCAMalpha, -beta, and -gamma. We generated mutant mice lacking specifically S-SCAMalpha. S-SCAMalpha-deficient mice breathe and feed normally but die within 24 h after birth. Primary(More)
Mammalian nuclear Dbf2-related (NDR) kinases (LATS1 and 2, NDR1 and 2) play a role in cell proliferation, apoptosis and morphological changes. These kinases are regulated by mammalian sterile 20-like kinases (MSTs) and Mps one binder (MOB) 1. Okadaic acid (OA), which activates MST2, facilitates the complex formation of MOB1, MST2 and NDR1 in HEK293FT cells.(More)
Junctional adhesion molecule 4 (JAM4) is a cell adhesion molecule that interacts with a tight junction protein, membrane-associated guanylate kinase inverted 1 (MAGI-1). Our previous studies suggest that JAM4 is implicated in the regulation of paracellular permeability and the signalings of hepatocyte growth factor. In this study, we performed yeast(More)
The Ras-association domain family (RASSF) comprises six members (RASSF1-6) that each harbors a RalGDS/AF-6 (RA) and Sav/RASSF/Hippo (SARAH) domain. The RASSF proteins are known as putative tumor suppressors but RASSF6 has not yet been studied. We have here characterized human RASSF6. Although RASSF6 has RA domain, it does not bind Ki-Ras, Ha-Ras, N-Ras,(More)
Membrane-associated guanylate kinase inverted (MAGI)-1 plays a role as a scaffold at cell junctions in non-neuronal cells, while S-SCAM, its neuronal isoform, is involved in the organization of synapses. A search for MAGI-1-interacting proteins by yeast two-hybrid screening of a kidney cDNA library yielded dendrin. As dendrin was originally reported as a(More)
The Hippo pathway restricts cell growth and proliferation and promotes apoptosis to control organ size. The Drosophila melanogaster isoform of RASSF (Ras association domain family; dRASSF) antagonizes proapoptotic Hippo signaling by inhibiting the binding of the adaptor protein Salvador to the kinase Hippo. Paradoxically, however, dRASSF also functions as a(More)
OBJECTIVE We reported at the previous annual meeting that LIPUS treatment of the molar tooth sockets of retired breeder rats accelerated alveolar bone healing, and that associated humoral effects were seen with elevated blood flow. Namely, LIPUS induced VEGF/angiogenesis along with elevated baseline blood flow rate, which was further associated with a(More)
Various scaffold proteins, such as PSD-95 and gephyrin, play an important role at excitatory and inhibitory synapses in the brain. The physiological importance of these proteins is underscored by the results of studies using mutant mice. PSD-95 mutant mice show impaired learning and lack of neuropathic sensitization (9, 28). Gephyrin-deficient mice fail to(More)
We describe herein a 72-year-old woman with tumor recurrence in the residual pancreas and metastasis to the liver following a pylorus-preserving pancreatoduodenectomy for multiple endocrine tumors in the head of the pancreas. Abdominal ultrasonography performed 7 years after the initial surgery detected new lesions in the residual pancreas and liver. After(More)
