Pallial and subpallial morphological subdivisions of the developing chicken telencephalon were examined by means of gene markers, compared with their expression pattern in the mouse. Nested expression domains of the genes Dlx-2 and Nkx-2.1, plus Pax-6-expressing migrated cells, are characteristic for the mouse subpallium. The genes Pax-6, Tbr-1, and Emx-1(More)
The single-minded (sim) gene encodes a transcriptional regulator that functions as a key determinant of central nervous system (CNS) midline development in Drosophila. We report here the identification of two murine homologs of sim, Sim1 and Sim2, whose products show a high degree of sequence conservation with Drosophila SIM in their amino-terminal halves,(More)
Pallial and subpallial morphological subdivisions of the mouse and chicken telencephalon were examined from the new perspective given by gene markers expressed in these territories during development. The rationale of this approach is that common gene expression patterns may underlie similar histogenetic specification and, consequently, comparable(More)
Expression of the Emx-1 homeobox gene is largely restricted to the developing and mature cerebral cortex. To study its function, two lines of mice were generated using gene targeting methods that have a deletion that includes the N-terminal coding region of Emx-1. Mice homozygous for the deletion were viable and fertile and exhibited no obvious behavioral(More)
Almost all bacteria possess glutamate racemase to synthesize d-glutamate as an essential component of peptidoglycans in the cell walls. The enforced production of glutamate racemase, however, resulted in suppression of cell proliferation. In the Escherichia coli JM109/pGR3 clone, the overproducer of glutamate racemase, the copy number (i.e. replication(More)
Bacillus subtilis possesses two isogenes encoding glutamate racemases, the poly-gamma-glutamate synthesis-linking Glr enzyme and the YrpC isozyme, and produces abundant amounts of the Glr enzyme. The YrpC isozyme, but not the Glr enzyme, was found to influence the activity of DNA gyrase, as did the MurI-type glutamate racemase of Escherichia coli, which is(More)
