is heterochromatin used for recombination
Moreover, Ccq1 has been implicated in the inhibition of recombination at telomeres (19, 20). Similar to taz1 Î´ and ccq1 Î´ cells, poz1 Î´ cells are also defective in transcriptional silencing of a marker gene inserted near telomeres, indicative of a failure in proper heterochromatin formation (35).
