General Information

No. Gene Name(s) Paragraph Text
2321 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.
2317 JUB1 This protein co-localizes with Pdd1p in heterochromatin body in the new macronucleus.

2317 JUB2, COI6, COI3, JUB4, HPL2 This protein co-localizes with Pdd1p in heterochromatin body in the new macronucleus.
2320 COI7, COI6 Coi7p directly interacts with Coi6p and is required for the stable accumulation of Coi6p.
