RNA-induced silencing complex (RISC/RITS) remodeling complexes to chromatin to form heterochromatin in telomeres.

The siRNA complex promotes methylation of histone H3K9 by the Clr4 methyltransferase (also known as KMT1, a homolog of Drosophila Su[Var]3–9). H3K9 methylation recruits the S. pombe homolog of HP1, Swi6.
