Gan, Miao. « Analysis of Chriz involved in Drosophila polytene chromosome structuring and binding ». Doctoral thesis, Humboldt-Universität zu Berlin, Mathematisch-Naturwissenschaftliche Fakultät I, 2009. http://dx.doi.org/10.18452/16000.
Texte intégralDrosophila polytene chromosomes are compacted into a series of bands and interbands. Z4 is a protein to keep this pattern, since Z4 mutant larvae show a decompaction of chromosomes and a loss of banding pattern (Eggert et al., 2004). By coimmuno-precipitation, we identified a chromodomain protein, which we named Chriz, for chromodomain protein interacting with Z4 (Gortchakov et al., 2005). In my PhD thesis, I tested the interactions between the full length proteins and different fragments of Chriz and Z4 which showed that Chriz could directly interact with Z4 in vivo. The interaction domains were mapped and it was determined that the N terminus of Z4 and the C terminus of Chriz are sufficient for mutual interaction. GST pull down confirmed these data and more precisely localized the interaction domains. Chriz, like Z4, is present in many interbands of interphase polytene chromosomes. The overexpression of different domains of Chriz demonstrated that both the N and C terminus are sufficient for targeting of Chriz to interbands. The C terminus was shown to be sufficient for rescue of Chriz null mutations into larva stage. Chriz full length proteins, with site directed mutations within the chromodomain, could still partially rescue the null mutant. Chriz RNAi knock down resulted in a loss of structure of polytene chromosome. The similar chromosomal phenotype of Z4 and Chriz indicate that they cooperate in the formation of chromosomal structure. Using the Chriz RNAi, I showed that Z4 chromosomal binding is dependent on Chriz. However, by a similar assay I showed that Chriz binding did not depend on Z4. Finally, the decondensed interphase chromatin marker Jil-1, a H3S10 histone kinase, and H3pS10 are decreased in Chriz RNAi line. From these data, I conclude that Chriz/Z4/Jil-1 form an interband binding complex. Chriz is the fundamental factor for the chromosomal targeting and stabilitation of the complex that is required to maintain locally chromatin structure.

Texte intégralPolytene chromosomes of Drosophila melanogaster provides an ideal model-system for the analysis of the mechanisms needed for chromosomal domain formation. Condensed as well as decondensed chromosomal domains can be formed by manipulating and reconstructing the polytene banding pattern. This possibility i ha-ve used for the establishment of an experimental system to study the structural requirements for open chromatin formation. Therefor i have generated a condensed chromatin domain at ectopic positions. This condensed „model“ domain provides a defined genetic context for the targeted insertion of sequences of interest, excluding any variable position effects. This allows comarative analysis of different sequences in order to identify the structural requirements for open chromatin formation. For this purpose the 61C7/8 interband sequence was targetly integrated into the condensed „model“ domain by site-specific recombination. Thereby i could show that the 61C7/8 interband sequence maintains the capacity to form open chromatin cognizable by the splitting of the condensed „model“ domain. Furthermore the newly formed open chromatin domain also keeps epigenetic characteristica like transcriptional activity or the recruitment of typical proteins. By deletion analysis, i have mapped the essential region needed for open chromatin formation to a ~490bp fragment located in the proximal part of the 61C7/8 interband sequence. This fragment overlaps binding sites for characteristic proteins known to be involved in chromosomal domain formation like the chromatin protein Chriz, the histone kinase Jil1 or the insulator protein CP190. Furthermore the fragment overlaps a promoter region that locates between the Rev1 and Med30 genes.

Texte intégralAt least three important mechanisms are known to maintain gene expression patterns: the chromatine state, the epigenetic modifications due to the Polycomb ( PcG) and Trithorax ( TrxG ) groups proteins, and non coding RNAs (ncRNAs). The PcG and trxG genes maintain cell identity through epigenetic modifications of chromatin, thereby maintaining a predefined transcriptional state that establishes "cell memory". Three proteins, i. E. Batman (BAN), Trithorax-like (GAF) and Pipsqueak (PSQ) are components of a DNA-binding cell memory complex. The first goal of my thesis was to refine the description of complexes containing BAN, GAF and PSQ bound to their targets. I showed the existence of several complexes, suggesting a combinatory composition of these complexes depending on the target. Using dsRNA-driven extinction of each of the three proteins, I determined the hierarchy of their recruitment. The extension of this approach to other PcG and trxG proteins lead us to propose a new model for the recruitment of several of the memory complexes. I also studied the link between heterochromatin formation and ncRNAs. By using mutants affecting pathways of ncRNAs production, I showed that they participate in the localization of the heterochromatin protein HP1 on polytene chromosomes and thus in the formation of heterochromatin. All these studies allowed us to characterize the complexity of relations between BAN, GAF and PSQ and to define their respective contribution in the differential recruitment of PcG or TrxG complexes, but also to contribute to establishing the link between the ncRNAs and heterochromatin

Texte intégralWith the idea of identify some of these proteins involved in the folding process of the proteins synthesized on the Rhynchosciara salivary gland, this project started adopting the shotgun cDNA sequencing strategy. This cDNA library was constructed utilizing salivary glands of Rhynchosciara americana at a developmental period where the cocoon construction begins. Messengers of important proteins involved in the folding, transport and proteolysis process were isolated, some examples are hsc70, hsp83, hip, hop, sec61 α/β, sec23, signal peptidase, rab7, signal recognition particle (srp), ubiquitin conjugating enzyme e 26 proteasome regulatory complex, cop 1 and ubiquitin ligase. Identification of these genes allowed the screening of genomic clones from a phage library; hsc70 and hsp83 characterization was carried out to verify the arrangement of these genes on genome of Rhynchosciara americana. The study of these genes will contribute with phylogenetic information about the specie. The mRNA expression of these genes was analyzed during several periods of the last larval developmental stage. In situ localization showed that these genes are located in polytene chromosomes regions near two DNAs puffs, C3 and C8. The expression levels of the proteins codified by genes hsc70 and hsp83 showed different behaviors of these genes under heat stress conditions and mainly, that the regulation of the proteins Hsc70 and Hsp83 can be related to the period of development of the larvae of Rhynchosciara americana. When revealed by immunofluorescence, Hsc70 protein shows localization predominantly on the cytoplasm.
