JUB6		This protein co-localizes with Pdd1p in heterochromatin body in the new macronucleus.
115COI6,
JMJ1,
LIA5,
COI7		Coi6p, its interaction partners Coi7p and Lia5p, and the histone demethylase Jmj1p are crucial for confining the production of small RNAs and the formation of heterochromatin to the eliminated sequences. The loss of Coi6p, Coi7p or Jmj1p causes ectopic DNA elimination.
114COI7,
COI6		Coi7p directly interacts with Coi6p and is required for the stable accumulation of Coi6p.
