Binding of [3H]AMPA was increased above control levels in rat brain membranes that had been incubated with concanavalin A (Con A) or a lectin from Lens culinaris (LC), both of which bind mannose residues. This did not occur with any of six lectins with other specificities. The magnitude of the increased binding varied from 15% in cortex to 70% in(More)
BACKGROUND Spinal muscular atrophy is caused by reduced levels of the survival of motor neurons (SMN) protein. SMN is found in large complexes with Sm proteins and at least eight other proteins, including seven "gemins". These complexes are involved in the assembly of snRNPs in the cytoplasm and their transport into the nucleus, but the precise roles of the(More)
Understanding networks of interacting proteins is a major goal in cell biology. The survival of motor neurons protein (SMN) interacts, directly or indirectly, with a large number of other proteins and reduced levels of SMN cause the inherited disorder spinal muscular atrophy (SMA). Some SMN interactions are stable and stoichiometric, such as those with(More)
Nesprin-1-giant and nesprin-2-giant regulate nuclear positioning by the interaction of their C-terminal KASH domains with nuclear membrane SUN proteins and their N-terminal calponin-homology domains with cytoskeletal actin. A number of short isoforms lacking the actin-binding domains are produced by internal promotion. We have evaluated the significance of(More)
OBJECTIVE Hyperactivity, one of the core symptoms of ADHD, has been mostly neglected in neuropsychological assessment of childhood ADHD. The neuropsychological Quantified behavior Test (QbTest) separately assesses all three core symptoms of ADHD on a behavioral level. Factor structure of the QbTest and its concurrent and discriminant validity are presented.(More)
Five subtypes of dopamine receptor exist in two subfamilies: two D(1)-like (D(1) and D(5)) and three D(2)-like (D(2), D(3) and D(4)). We produced novel monoclonal antibodies against all three D(2)-like receptors and used them to localize receptors in Ntera-2 (NT-2) cells, the human neuronal precursor cell line. Most of the immunostaining for all three(More)
Nesprin-1-giant (1008kD) is a protein of the outer nuclear membrane that links nuclei to the actin cytoskeleton via amino-terminal calponin homology domains. The short nesprin-1 isoform, nesprin-1-α2, is present only in skeletal and cardiac muscle and several pathogenic mutations occur within it, but the functions of this short isoform without calponin(More)
