ProteomicsThe nucleosomal acidic patch relieves auto-inhibition by the ISWI remodeler SNF2h
Domain level interactions between the ISWI remodeler SNF2h and reconstituted mononucleosomes were probed by EDC crosslinking under different biochemical conditions: ADP, ADP-BeFx, ADP-BeFx with LANA peptide added (which binds at the acidic patch). A semi quantitative approach was used to monitor do...

ProteomicsConcerted regulation of ISWI by an autoinhibitory domain and the H4 N-terminal tail
ISWI-family nucleosome remodeling enzymes need the histone H4 N-terminal tail to mobilize nucleosomes. Here we mapped the H4-tail binding pocket of ISWI. Surprisingly the binding site was adjacent to but not overlapping with the docking site of an auto-regulatory motif, AutoN, in the N-terminal regi...

ProteomicsAffinity Purification of ISWI chromatin remodeler in Trypanosoma cruzi
Chromatin remodeling is a general mechanism involved in DNA-dependent processes, including gene expression regulation. ISWI ATPase is the catalytic subunit in diverse chromatin remodeling complexes that changing histone–DNA interactions and therefore play a pivotal role in different nuclear processe...

GenomicsDynamics of yeast ISWI and CHD chromatin remodeler genomic association (part 1)
Chromatin remodelers influence genetic processes by altering nucleosome occupancy, positioning, and composition. In vitro, yeast ISWI and CHD remodelers require > 20 bp of extranucleosomal DNA for remodeling, but linker DNA in S. cerevisiae averages < 20 bp. To resolve this paradox, we have mapped t...

TranscriptomicsRNAi profiling of Drosophila SL2 cells knocked down for ISWI
Profiling of changes in steady state RNA levels upon RNAi-mediated knockdown of the nucleosome remodeling ATPase ISWI in Drosophila SL2 cells. Quantitation of the corresponding proteomes has been performed to describe transcriptome-proteome relations. The analysis indicates a limited correlation of ...

TranscriptomicsThe ISWI ATPase Snf2L is required for superovulation and regulates Fgl2 in differentiating mouse granulosa cells
We investigate the role of Snf2l in ovaries by characterizing a mouse bearing an inactivating deletion on the ATPase domain of Snf2l (Ex6DEL). Snf2l mutant mice produce significantly fewer eggs than control mice when superovulated. Thus, gonadotropin stimulation leads to a significant deficit in sec...
