Homer is a neuronal immediate early gene (IEG) that is enriched at excitatory synapses and binds group 1 metabotropic glutamate receptors (mGluRs). Here, we characterize a family of Homer-related proteins derived from three distinct genes. Like Homer IEG (now termed Homer 1a), all new members bind group 1 mGluRs. In contrast to Homer 1a, new members are(More)
A thioredoxin reductase (TrxR) has been identified in the hyperthermophilic archaeon Sulfolobus solfataricus (Ss). This enzyme is a homodimeric flavoprotein that was previously identified as NADH oxidase in the same micro-organism ('Biotechnol. Appl. Biochem. 23 (1996) 47'). The primary structure of SsTrxR is made of 323 amino acid residues and contains two(More)
From 1974 through 1989, 36 patients with arteriovenous malformations were studied in the neurosurgical department of the Santobono Children's Hospital in Naples; 7 of these patients were younger than three years of age: 5 underwent surgery. The remaining 2 patients presented, respectively, an aneurysm of the vein of Galen and an arteriovenous malformation(More)
