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)
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 most common properties of oncogenes are cell proliferation and the prevention of apoptosis in malignant cells, which, as a consequence, induce tumor formation and dissemination. However, the effects of oncogenes on the tumor microenvironment (TME) have not yet been examined in detail. The accumulation of ascites accompanied by chronic inflammation and(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)
