Architectural Proteins ChIP-Seq (Kc167) (insulatorsChIPSeq) Track Description

Description

These tracks show the results of the ChIP-Seq analyses of architectural proteins (also known as insulators) from Kc167 cells. The regions that are enriched in the architectural proteins were identified by MACS2 and Peakzilla. The log likelihood ratio evidence tracks were produced by MACS2.

The ChIP-Seq datasets were obtained from the Gene Expression Omnibus database at NCBI under the following accession numbers:

Accession	Insulators	Reference

GSE39521	Myc	Yang J et al., Nat Commun. 2013
