Mass spectrometry analysis of the impact of replication stress upon phosphorylation and protein interaction of human RIF1 protein

ABSTRACT: Wild-type or S2265A version of GFP-RIF1 protein (isoform 1) was over-expressed in Flp-In-T-REx cells (Watts et al. 2020. eLife 9:e58020) and immunopurified using GFP-Trap magnetic agarose beads. Proteins were subjected to on-beads trypsin digestion and resulting peptides were analysed by mass spectrometry for protein identification/quantification and identification of phosphorylated residues. Raw MS file names and descriptions: IP_RIF1_A.raw = GFP-RIF1-L immunoprecipitated from cells without aphidicolin treatment. IP_RIF1_B.raw = GFP-RIF1-L immunoprecipitated from cells treated with 1 µM aphidicolin for 24 hr before harvesting. IP_RIF1_C.raw = GFP-RIF1-L (S2265A) immunoprecipitated from cells treated with 1 µM aphidicolin for 24 hr before harvesting.

ASF1 acts with RIF1 to promote DNA end-joining in BRCA1 deficient cells

Project description:RIF1 acts downstream of 53BP1 to coordinate DNA double strand break repair pathway choice between non-homologous end joining (NHEJ) and homologous recombination (HR). Here we identified ASF1 as an endogenous RIF1-associated protein. We showed that ASF1 forms complex with RIF1 and regulates RIF1-dependent functions in DNA damage response.

SILAC APMS analysis of SRP14 interactome in HEK-293 cells

Project description:The Signal Recognition Particle (SRP) is a universally conserved and abundant ribonucleoprotein particle (RNP) in cells. Its composition and size vary across evolution. In mammals, SRP comprises one RNA molecule, the 7SL RNA, and six proteins: SRP14, SRP14, SRP19, SRP54, SRP68, and SRP72. SRP is essential for targeting transmembrane and secreted proteins to the endoplasmic reticulum. To reveal novel aspects of SRP biogenesis, we established the interactome of the GFP-SRP72 protein. To do so, we have produced stable human U2OS cell line expressing GFP-SRP14 and performed stable isotope labeling by amino acids in cell culture (SILAC) proteomic experiment using GFP-SRP14 as bait.

Genome-wide analysis reveals that budding yeast Rif1 binds to replication origins and at blocked replication forks to protect nascent DNA

Project description:This experiment details ChIP sequencing to decipher the binding sites of the Rif1 protein in budding yeast. Rif1 binds most strongly to telomeres where its binding is mediated by Rap1. To reduce telomere binding and help reveal Rap1-independent binding sites, a truncation mutant of Rif1 lacking the Rap1 interaction domain was constructed and analysed. Binding was examined at various cell-cycle stages to elucidate the role of Rif1 in DNA replication and other chromosome transactions.
