LCCS1 pathology linked to defects in Gle1 oligomerization and mRNA export disregulation
Oct. 24, 2013—Summary The conserved multifunctional protein Gle1 regulates gene expression at multiple steps: nuclear mRNA export, translation initiation, and translation termination. A GLE1 mutation (FinMajor) is causally linked to human lethal congenital contracture syndrome-1 (LCCS1); however, the resulting perturbations on Gle1 molecular function were unknown. FinMajor results in a proline-phenylalanine-glutamine peptide insertion within the uncharacterized Gle1...
Retinotopic maps in the pulvinar of bush baby
Oct. 15, 2013—Retinotopic maps in the pulvinar of bush baby (otolemur garnettii) K. Li1, J. Patel2, G. Purushothaman2, R.T. Marion3 andV.A. Casagrande1,2,3,4,* Article first published online: 23 AUG 2013 DOI: 10.1002/cne.23358 Abstract Despite its anatomical prominence, the function of the primate pulvinar is poorly understood. A few electrophysiological studies in simian primates have investigated the functional organization...

CK1 is required for a mitotic checkpoint that delays cytokinesis
Oct. 7, 2013—CK1 is required for a mitotic checkpoint that delays cytokinesis Alyssa E. Johnson, Jun-Song Chen, Kathleen L. Gould Highlights •Dma1’s FHA domain binds to a pTXXpS phosphomotif on Sid4 •CK1 is required for Dma1-dependent Sid4 ubiquitination •CK1 phosphorylation of Sid4 is required for the Dma1-dependent mitotic checkpoint •CK1 concentrates at SPBs and phosphoprimes Sid4 for...
An oligomeric switch that modulates cytokinetic formin function
Oct. 1, 2013—SIN-dependent phosphoinhibition of formin multimerization controls fission yeast cytokinesis K. Adam Bohnert1, Agnieszka P. Grzegorzewska2,3,6, Alaina H. Willet1, Craig W. Vander Kooi4,5, David R. Kovar2,3 and Kathleen L. Gould1,7 Abstract Many eukaryotes accomplish cell division by building and constricting a medial actomyosin-based cytokinetic ring (CR). In Schizosaccharomyces pombe, a Hippo-related signaling pathway termed the septation...
Generalized ideal observer model for decoding sensory neural responses
Sep. 19, 2013—A Generalized ideal observer model for decoding sensory neural responses Gopathy Purushothaman and Vivien A. Casagrande Front. Psychol., 19 September 2013 | doi: 10.3389/fpsyg.2013.00617 Abstract We show that many ideal observer models used to decode neural activity can be generalized to a conceptually and analytically simple form. This enables us to study the statistical properties...
Post-doc Publication: CRISPR/Cas9 method in zebrafish
Aug. 14, 2013—A simple and robust method for targeted mutagenesis in zebrafish has long been sought. Previous methods generate monoallelic mutations in the germ line of F0 animals, usually delaying homozygosity for the mutation to the F2 generation. Generation of robust biallelic mutations in the F0 would allow for phenotypic analysis directly in injected animals. Recently the...
