The focus of our analysis will be elements that specify nucleosome
positioning and occupancy, control domains of gene expression, induce
repression of the X chromosome, guide mitotic segregation and genome
duplication, govern homolog pairing and recombination during meiosis,
and organize chromosome positioning within the nucleus. Our 126
strategically selected targets include RNA polymerase II isoforms,
dosage-compensation proteins, centromere components, homolog-pairing
facilitators, recombination markers, and nuclear-envelope constituents.
We will integrate information generated with existing knowledge on the
biology of the targets and perform ChIP-chip analysis on mutant and RNAi
extracts lacking selected target proteins.
