Rif1 S-acylation mediates DNA double-strand break repair at the inner nuclear membrane

Abstract

Rif1 is involved in different processes such as telomere homeostasis, DNA replication timing, and DNA double strand break (DSB) repair pathway choice. Here, the authors reveal that Rif1 S-acylation facilitates the accumulation of Rif1 at DSBs, attenuation of DNA end-resection, and DSB repair by non-homologous end-joining.
