This track shows the classification of the genome into 5 discrete domains based on the DamID binding profiles of 53 chromatin proteins in Drosophila Kc167 cells. The characteristics of each of the five states are summarized below:
State
Description
Color
Green
Classic (including pericentric) heterochromatin
Blue
Polycomb Group (PcG) chromatin; subject to epigenetic silencing
Black
Transcriptionally silent (in cell type assayed); probably dynamic
Red
Transcriptionally active euchromatin; genes usually developmentally regulated
Yellow
Transcriptionally active euchromatin; genes usually broadly expressed
