Stage-specific chromosomal association of Drosophila dMBD2/3 during genome activation.
2002
The Drosophila gene dMBD2/3 encodes a protein with significant homologies to the mammalian methyl-DNA binding proteins MBD2 and MBD3. These proteins are essential components of chromatin complexes involved in epigenetic gene regulation. Because the available in vitro data on dMBD2/3 are conflicting we have started an in vivo characterization of dMBD2/3. We detected expression of two isoforms specifically during embryonic development. Staining of whole embryos combined with high-resolution confocal microscopy revealed a highly regulated spatial distribution. During the syncytial blastoderm stage, dMBD2/3 formed speckles that localized to the cytoplasm. Shortly after, during the cellular blas…
The DrosDel Deletion Collection: A Drosophila Genomewide Chromosomal Deficiency Resource
2007
AbstractWe describe a second-generation deficiency kit for Drosophila melanogaster composed of molecularly mapped deletions on an isogenic background, covering ∼77% of the Release 5.1 genome. Using a previously reported collection of FRT-bearing P-element insertions, we have generated 655 new deletions and verified a set of 209 deletion-bearing fly stocks. In addition to deletions, we demonstrate how the P elements may also be used to generate a set of custom inversions and duplications, particularly useful for balancing difficult regions of the genome carrying haplo-insufficient loci. We describe a simple computational resource that facilitates selection of appropriate elements for generat…
