Study: Genome-wide distribution of the three condensin complexes in C. elegans
show Abstracthide Abstract
Condensins are multi-subunit protein complexes that regulate chromosome structure throughout cell-cycle. Metazoans contain two types of condensin complexes (I and II) with essential and distinct functions. In C. elegans a third type of condensin (IDC) functions as part of the X chromosome dosage compensation complex1,2. We mapped genome-wide binding sites of the three condensin types in C. elegans embryos. Characteristics of condensin binding are similar between condensin types. Overall design: ChIP-seq profiles of C. elegans subunits of the three condensins in 3-6 replicates from mixed stage embryos, controls are included, and RNA-Seq profiles of C. elegans in 5 replicates from mixed staged embryos. Additionally, ChIP-seq profiles of the condensin II subunit KLE-2 in 6 replicates from L3 with controls, and RNA-Seq profiles of KLE-2 mutants in 3 replicates each from L3.

Library:
Instrument: Illumina HiSeq 2000
Strategy: ChIP-Seq
Source: GENOMIC
Selection: ChIP
Layout: SINGLE
Construction protocol: Embryos were washed and dounced in FA buffer (50 mM HEPES/KOH pH 7.5, 1 mM EDTA, 1% Triton X-100, 0.1 % sodium deoxycholate; 150 mM NaCl). 0.1 sarkosyl was added before sonicating to obtain chromatin fragments of majority between 200-800 bp. 1-2 mg of embryo extract and 3-5 ug of antibody was used per ChIP. Half of the ChIP DNA were ligated to Illumina or home-made multiplexed adapters and amplified by PCR. Library DNA between 250-500 bp in size was gel purified.
