HP6/Umbrea, a rapidly evolving Drosophila HP1-family paralog, is a candidate HP1a-recruited plasticizer of heterochromatin
It is proposed that HP6/Umbrea acts like a plasticizer, a molecular softener that could make otherwise silenced heterochromatic genes leakier and thus potentially act as a rheostat for leaky transcription.
