RIF1

DNA-binding protein RIF1, L000001639, YBR275C
Protein that binds to the Rap1p C-terminus; acts synergistically with Rif2p to help control telomere length and establish telomeric silencing; contributes to resection of DNA double strand breaks (DSBs); deletion results in telomere elongation

Phenotypic Enhancement

A genetic interaction is inferred when mutation or overexpression of one gene results in enhancement of any phenotype (other than lethality/growth defect) associated with mutation or over expression of another gene.

Publication

γH2A is a component of yeast heterochromatin required for telomere elongation.

Kitada T, Schleker T, Sperling AS, Xie W, Gasser SM, Grunstein M

Histones of heterochromatin are deacetylated in yeast and methylated in more complex eukaryotes to regulate heterochromatin structure and gene silencing. Here, we report that histone H2A phosphorylated at serine 129 (γH2A) in Saccharomyces cerevisiae is a conceptually new type of heterochromatin modification that functions downstream of silent chromatin assembly. We show that γH2A is enriched throughout yeast telomeric and silent ... [more]
