UniProtKB description: Structural component of heterochromatin, involved in gene repression and the modification of position-effect-variegation. Recognizes and binds histone H3 tails methylated at 'Lys-9', leading to epigenetic repression. Stabilizes chromatin-associated RNAs probably by binding to them and thereby preventing their degradation (PubMed:26389589). Associates with, and may be a part of, the HipHop-HOAP complex that recruits the MTV complex to form the terminin telomere-capping complex, which binds to chromosome ends in a sequence-independent manner and prevents telomere fusion (PubMed:12510197, PubMed:20057353). Telomere capping is independent of the origin recognition complex (ORC) (PubMed:12510197).
