## Overview

This super-track combines related tracks of DNaseI sensitivity data from University of Washington (UW).

DNaseI has long been used to map general chromatin accessibility and the DNaseI "hyperaccessibility" or "hypersensitivity" that is a universal feature of active cis-regulatory sequences. The use of this method has led to the discovery of functional regulatory elements that include enhancers, insulators, promotors, locus control regions and novel elements. DNaseI hypersensitivity signifies chromatin accessibility following binding of trans-acting factors in place of a canonical nucleosome, and is a universal feature of active cis-regulatory sequences in vivo.

These tracks contain DNaseI analysis of multiple cell lines using the QCP method or DNaseI-chip.
