How does the ORF1p perform its multiple functions to facilitate LINE1 retrotransposition? And what enables its ability to also facilitate replication of other retrotransposons? Find out in our newly published paper in @NAR_Open doi.org/10.1093/nar/gkae1141

In @VirusesMDPI, our single molecule measurements of basic residue mutants reveal that HIV-1 NC condenses dsDNA via a primarily electrostatic mechanism, which is needed to maintain viral core stability during reverse transcription. doi.org/10.3390/v16060872

What triggers HIV-1 capsid uncoating? In @ScienceAdvances, with the Pathak lab at NCI, we show long dsDNA from reverse transcription is required for uncoating, likely due to mechanical pressure regulated by the nucleocapsid protein. science.org/doi/10.1126/scia…

The T4 gp32 CTD recruits and stabilizes proteins within the model T4 replication complex. Does it serve other roles? Our new @JMolBiol paper shows that the CTD facilitates rapid removal of gp32 from ssDNA to ensure prompt genomic processing. doi.org/10.1016/j.jmb.2024.1…

Can the sequence nonspecific single-stranded DNA binding protein E. coli SSB detect DNA damage? @WilliamsLabNEU and @BeuningLabNEU collaborated to show in @BiophysJ that the SSB binding conformation changes in response to DNA damage. doi.org/10.1016/j.bpj.2023.0…

How are T4 gene 32 (gp32) proteins rapidly removed from a stable filament during DNA replication? Our new @NAR_Open paper shows how gp32 can wind ssDNA in multiple conformations to facilitate rapid protein dissociation. doi.org/10.1093/nar/gkad595 #opticaltweezers #singlemolecule

Like other HMGB proteins, human FACT destabilizes nucleosomes to facilitate transcription. Why is the rest of this large protein needed? doi.org/10.1016/j.celrep.202… shows that the SSRP1 HMGB domain coordinates with the SPT16 domain to facilitate nucleosome reassembly after disruption

The N protein of SARS-CoV-2, the virus responsible for COVID-19, is essential for viral replication, making it an attractive drug target. The N protein contains two primary structural domains. How do they coordinate to compact the viral genome? Find out in doi.org/10.1093/nar/gkac1179
