GenomicsSequencing-based ssDNA detection
Meiotic DNA double stranded breaks (DSBs) initiate genetic recombination in discrete areas of the genome called recombination hotspots. Although DSBs can be directly mapped using ChIP-Seq and antibody against ssDNA-associated proteins, genome-wide mapping of recombination hotspots in mammals is stil...

ProteomicsRPA promotes processive ssDNA digestion by Dna2 via their bimodal interaction in Saccharomyces cerevisiae
Single-stranded DNA (ssDNA) widely exists as intermediates in DNA metabolic pathways. The ssDNA binding protein, RPA, not only protects the integrity of ssDNA, but also directs the downstream factor that signals or repairs the ssDNA intermediate. However, it remains unclear how these enzymes/factors...

TranscriptomicsssDNA mapping in dmc1 strains
ssDNA enrichment was used to map and compare DSB hotspots in dmc1, pch2 dmc1, sir2 dmc1, orc1-161 dmc1, dmc1 rdnadelete and dmc1 chr2:12 translocation strains. 6 samples, 2 replicates each. Averaged data is available as a supplementary file on the Series record (below).

TranscriptomicsssDNA in S phase compared to G1 phase at different timepoints
To identify origins of replication in Lachancea waltii by mapping regions of ssDNA that are enriched in S phase. L. waltii cells are grown in the presence of hydroxyurea, which slows replication forks and causes the accumulation of ssDNA at the replication fork.

ProteomicsFor origin melting Rep nucleoprotein complex accommodates both dsDNA and ssDNA of DUE
The replication initiation proteins interact dsDNA located at replication origin and ssDNA of DNA unwinding element (DUE), formed as a result of the destabilization of the double-stranded helix of AT-rich origin region. It is a critical step in the DNA replication initiation; however, the structure ...

TranscriptomicsDSB formation in replication compromised cells
DSBs were mapped genome-wide by ssDNA enrichment in cdc6-mn replication comprimsied strains. We mapped DSB sites by detecting DSB-associated ssDNA enrichment on microarrays. To test the role of DNA replication in DSB formation, we mapped ssDNA in a cdc6-mn replication depleted strain. ssDNA was isol...

ProteomicsPhase separation properties of RPA combine high-affinity ssDNA binding with dynamic condensate functions at telomeres
RPA has been shown to protect single-stranded DNA (ssDNA) intermediates from instability and breakage. RPA binds ssDNA with sub-nanomolar affinity, yet dynamic turnover is required for downstream ssDNA transactions. How ultrahigh-affinity binding and dynamic turnover are achieved simultaneously is n...
